The PM100USB Console is a compact power and energy meter interface which allows PC control of an attached power or energy sensor. It contains many of the same features as the PM100D and PM100A Consoles, except it does not have a display screen or built-in console controls. Instead, the console and sensor are completely controlled via a USB connection and the supplied software. The PM100USB converts the signal from the attached sensor and transfers it to the PC.

The PM100USB is compatible with more than 25 standard photodiode, slim photodiode, integrating sphere, fiber, thermal, and pyroelectric sensors (see Power Meter Compatibility Chart). Additionally, it allows the connection of unamplified anode or cathode grounded photodiodes with up to 5 mA photocurrent, thermal elements with a maximum output voltage of 1 V, and pyroelectric sensors with a maximum output voltate of 100 V. Depending on the connected sensor, it can measure optical powers in the range from 100 pW to 200 W and energy from 3 µJ to 15 J. When used together with the ultra compact S15xC Series fiber sensor, the PM100USB becomes a compact and portable fiber power meter that is ideal for multi sensor applications.

PM100x Series GUI
PM100USB Control Software

Computer Control
The PM100USB and connected sensor are controlled through a PC running the supplied software. The standard GUI offers three panels for the display of various numeric parameters, a larger main panel and two subpanels. The displayed parameter can be selected, i.e. power, energy and their min or max values as well as their units. The GUI offers data logging with graphical, tabular or histogram representation and statistical evaluation of the measurements. The data can be stored as a text file. A driver set for the integration into 3rd party software or customized applications is provided as well. For driver software, as well as programming reference guides for LabVIEW™, Visual C++, Visual C#, and Visual Basic, please see the Software tab.

Console Design
Like the PM100D the PM100USB features broad current and voltage measurement ranges and the capability of measuring power and energy. The AD converter allows for more measurement ranges of smaller spans, a higher acquisition rate, and higher precision. A selectable bandwidth of either 20 Hz or 100 kHz offers more flexibility and adaptability to specific measurement tasks while using photodiode sensors. The higher bandwidth is optimal for pulse-detection; the lower bandwidth offers better accuracy.

Additionally, the power meter can adapt to the thermal time constant of thermal sensors leading to significantly faster measurements with thermal sensors. Thermal sensors have an individual time constant that can vary greatly from unit to unit. Like the PM100D, the PM100USB can adjust to this individual constant for each sensor and thus minimize the response time of the system (sensor + console).

Fiber Power Meter Option
The compact, integrated, fiber sensors of the S15xC Series can be connected directly to the PM100USB turning the PM100USB into a compact, single unit fiber power meter. Any handling limitations due to cable movements or cable handling are avoided thus making this device ideal for multi-sensor applications that do not require a console but is controlled remotely via PC. The S150C offers exchangeable fiber adapters for FC, SMA, LC, SC, ST, and LC fiber connectors.

Sensor Options

The PM100USB console is compatible with more than 25 photodiode, slim photodiode, integrating sphere, fiber, thermal, and pyroelectric sensors covering the UV to the MIR. Additionally an unamplified anode or cathode grounded photodiode, with up to 5 mA photocurrent, thermal elements with up to 1 V output voltage, and pyroelectric sensors with max. 100 V output may be interfaced with the PM100USB. Depending on the application the sensor can measure optical powers in the range from 100 pW to 200 W and energy from 3 µJ to 15 J. A complete list of Thorlabs' C-Series sensors with selected specifications can be found on the Sensor Selection tab.

Please see the Applications tab for common sensor arrangements.

A selectable bandwidth of either 20 Hz or 100 kHz offers more flexibility and adaptability to specific measurement tasks while using photodiode sensors. The higher bandwidth is optimal for pulse-detection; the lower bandwidth offers better accuracy. Power and energy density can also be displayed based on user input beam areas. Optical sources may be attenuated / gained electronically through the console. Note: Attenuating the source through the console will not attenuate the light at the detector and damage may still occur above the detector threshold power.

Thorlabs' complete line of sensor heads are listed in the table to the right. Utilizing the variety of sensors, the PM100D can measure optical power and energy from CW and pulsed sources. Sensors are available for monitoring low power CW laser diode emission to high power excimer, YAG, and CO2 laser pulses.

The PM100USB can be used in the lab, as well as in the field with our fiber coupled sensors. Please see the Applications tab for a small sample of possible configurations. Contact tech support with any applications based questions.

Additionally, the PM100USB communicates with the sensor and accesses spectral response functions, time constants, and other information specific to the detector. The PM100USB then corrects for spectral response functions automatically. The power meter also accounts for the detector time constants (which can vary greatly, especially for Thermal sensors) for each sensor and can minimizes the response time of the system (sensor + console), thus greatly improving the efficiency of the unit.

Sensor Upgrade Service

Thorlabs' Sensors and PM100USB Console are not compatible with old power meter consoles and sensor heads, respectively. We offer a sensor upgrade service if you want to use your existing sensors with a new power meter console. Note: upgraded sensors will be incompatible with old power meter consoles and new sensors converted to work with older consoles will not be compatible with the PM100USB. Please contact our tech support team for details.

Standard Photodiode Sensor Mounting Options

Thorlabs Standard Photosdiode Sensors compact design allows easy integration into existing setups. Typical mounting configurations including post, cage, and lens tube options are available. Shown on this page are several different choices for mounting these sensors.

The Standard Photodiode Sensors are compatible with all S120-xx Series fiber adapters. FC/PC and SMA adapters are shown on the right. Adapters for SC, LC, and ST connections are also available.

Flip up mounts are convenient for quick power measurments from a static location. The sensor can be placed in the path of the laser beam for the power measurment and flipped down during normal operation of the system.

FM90 Right Angle Flip-Mounts are shown to the right. Thorlabs also offers the TRB1 Articulating Post Mount. The lockable articulating mount offers almost unlimited positioning of the sensor head. The articulating mount is shown on an S13xC Slim Photodiode Sensor below.

The Standard Photodiode Sensors also feature SM1 threaded connections on the front face. The SM1 theading provides easy mounting to 1" lens tube systems and quick release mounts.

Shown to the right are the KB1P Quick-Release Post Mount and QRC1A Quick-Release 30 mm Cage Mount. Both mounts feature SM1 threaded connections to the sensor heads.

Note: Due to the thickness of the S12xC sensor, the QRC1A and CP90F (shown below) quick release mounts can only be fully removed from the cage system by backing them off an open end. The two mounts are easily removed from the cage system if only three cage mounts are used. See the picture on the right.

Thorlabs also offers the CP90F 30 mm Cage Plates with Quick-Release Mounts. These mounts feature magnetically coupled mounting for easy and repeatable mounting.

Note: Like the QRC1A, the CP90F can not be removed from a closed cage system.

Slim Photodiode Sensor Mounting Options

Thorlabs' Slim Photodiode Sensors are designed to fit into tight optic arrangements such as cages, lens tubs, and optic dense free space arrangements.

Shown to the right is a S130C Sensor inserted into a 30 mm cage system. The application shown highlights the ease for which the sensor can be inserted into the cage, and the minimal space needed to take a power measurment.

The Slim Photodiode Sensors may also be mounted on a TRB1 Articulating Mount. This mount allows repeatable insertion of the sensor into tight optic arrangements. After the measurement is made, the sensor may be rotated out of the beam path for normal operation.

Integrating Sphere Photodiode Sensor Mounting Options

Thorlabs' Integrating Sphere Photodiode Sensor provides a low loss cavity for diverging, non-uniform, or off-axis beam measurements. These integrating spheres are ideal for all fiber based applications due to the beam divergence at the end of the fiber.

Shown to the right is an S140C Integrating Sphere with S120-FC Fiber Adapter. Also shown is an S140C with a S140-BFA Bare Fiber Adapter. The Bare Fiber adapter features a mounting clamp and light shield to decrease interference from ambient light.

Compact Fiber Photodiode Sensor Mounting Options

Thorlabs' Compact Fiber Photodiodes are the ideal choice for a portable, fiber coupled power meter. The S15xC sensors are compatible with a wide variety of fiber connections. PM20-xx adapters are available to couple FC, PC, SC, LC, SMA, and ST connectors with the sensors. Shown to the right is a S150C Sensor with FC and SMA connector adapters.

Shown to the far right is a PM100D console with S150C sensor connected to a FC connectorized optical fiber. This setup is ideal for portable in the lab and in the field use.

Pyroelectric Energy Sensor Mounting Options

Thorlabs' Pyroelectric Energy Sensors are ideal for measuring pulsed sources. These pyroelectric sensors provide direct energy readings for those sources. The sensors are designed to handle medium to high energy pulses from Excimer, YAG, and other high power lasers.

Mounting options include post (with insulating adapter) and cage configurations, shown to the right.

Multi-console option

Multi Console Option

Up to eight PM100x Series Power Meters can also be operated remotely using the PM100x Multi Console Utility. The integration of up to eight consoles greatly reduces clutter and allows easier monitoring of multiple light sources.

The free software tool allows the real time monitoring of up to eight PM100x Power Meters to be shown in a single plot. Simply connect your PM100A, PM100D, or PM100USB meters to a USB hub and download the power meter software and mutli-console utility here. Each meter's wavelength correction is set individually to allow for monitoring systems with multiple wavelengths.

Software for the PM100x Series

All PM100x Series Consoles are shipped with the latest software versions preloaded onto the console or on the USB memory stick. The latest software, firmware, drivers, and utilities for the PM100x Series Power and Energy Meters are also available for download at the link below.

The software download page also offers programming reference notes for interfacing with our power and energy meters using LabVIEW, Visual C++, Visual C#, and Visual Basic. Please see the Programming Reference tab on the software download page for more information and download links.

Firmware updates are available for the PM100A, PM100D, and PM100USB Consoles. Each of these consoles can be controlled remotely by a PC utilizing the remote control application software. A VXIpnp/VISA instrument driver is available for the Thorlabs PM100x Series Power Meter Consoles as well.

This tab outlines the full selection of Thorlabs' Power and Energy Sensors. Our photodiode and thermal sensors are compatible with all of Thorlabs' current line of power meter consoles, while our pyroelectric sensors are compatible with all of our current power meter consoles except for the PM100A Analog Power Meter Console. In addition to the power and energy sensors listed below, Thorlabs also offers all-in-one, wireless, handheld power meters and compact USB power meter interfaces that contain either a photodiode or a thermal sensor, as well as power meter bundles that include a console, sensor head, and post mounting accessories.

Thorlabs offers three types of sensors:

  • Photodiode Sensors: These sensors are designed for power measurements of monochromatic or near-monochromatic sources, as they have a wavelength dependent responsivity. These sensors deliver a current that depends on the input optical power and the wavelength. The current is fed into a transimpedance amplifier, which outputs a voltage proportional to the input current.
  • Thermal Sensors:  Constructed from material with a relatively flat response function across a wide range of wavelengths, these thermopile sensors are suitable for power measurements of broadband sources such as LEDs and SLDs. Thermal sensors deliver a voltage proportional to the input optical power.
  • Pyroelectric Energy Sensors: Our pyroelectric sensors produce an output voltage through the pyroelectric effect and are suitable for measuring pulsed sources, with a repetition rate limited by the time constant of the detector. These sensors will output a peak voltage proportional to the incident pulse energy.

Power and Energy Sensor Selection Guide

There are two options for comparing the specifications of our Power and Energy Sensors. The expandable table below sorts our sensors by type (e.g., photodiode, thermal, or pyroelectric) and provides key specifications.

Alternatively, the selection guide graphic further below arranges our entire selection of photodiode and thermal power sensors by wavelength (left) or optical power range (right). Each box contains the item # and specified range of the sensor. These graphs allow for easy identification of the sensor heads available for a specific wavelength or power range. 

Photodiode Power Sensors
Thermal Power Sensors
Pyroelectric Power Sensors
  • The response time of the photodiode sensor. The actual response time of a power meter using these sensors will be limited by the update rate of your power meter console.
  • For thermal sensors, the response time is limited by the sensor material. Thorlabs' thermal sensors and power meter consoles are designed so that the incident power can be determined after a single time constant of the sensor. As a result, our C-series thermal sensors have relatively low response times compared to other thermal sensors.
  • With Intermittent Use (Maximum Exposure Time of 20 Minutes)
  • All pyroelectric sensors have a 20 ms thermal time constant, τ. This value indicates how long it takes the sensor to recover from a single pulse. To detect the correct energy levels, pulses must be shorter than 0.1τ and the repetition rate of your source must be well below 1/τ.

Response from Bweh at Thorlabs USA: This may not be possible, even with a photodiode sensor though we have a 16 bit AD converter in the PM100USB. Speed loss could come from the queries of commands which always checks the availability/status of the sensor. You could write your own routines which allows for faster sampling rates but the USB 2.0 port will limit this and the PM100USB has no analog output to bypass this. You may consider instead the PM100D, PM100A or the PM200.

This is a response from Thomas at Thorlabs. Thank you very much for your feedback. The maximum achievable sampling rate is about 300Hz. The GUI provides a function called fast logging which enables the maximum logging frequency of the unit. If you want to sample a signal in the MHz range you could use one of our amplified photodetectors in combination with a scope. I will contact you directly to discuss your application.

Poster:tschalk
Posted Date:2013-07-10 08:40:00.0
This is a Response from Thomas at Thorlabs. Thank you very much for your inquiry. To control the device with Linux you would need a USBTMC-driver for Linux and the instrument-driver-code for the corresponding SCPI commands to communicate via the USBTMC driver. The low level specifications are the followings: - Universal Serial Bus Test and Measurement Class Specification (USBTMC) Revision 1.0. USB Implementers Forum. April 14, 2003 - and - Universal Serial Bus Test and Measurement Class, Subclass USB488 Specification (USBTMC-USB488) Revision 1.0. April 14, 2003 - and the command structures are - IEEE Std 488.2-1992; IEEE Standard Codes, Formats, Protocols, and Common Commands For Use With IEEE Std 488.1-1987, IEE Standard Digital Interface for Programmable Instrumentation - and the used command format is - Standard Commands For Programmable Instruments (SCPI) -. You can use the source code of our instrument driver which is an open source code under LGPL. This one can be changed so that it is possible to use the Linux - USBTMC communication instead of the NI functions. I will contact you directly for more detailed information.

A response from Julien at Thorlabs: Thank you for your feedback! The communication of the PM100USB is based on the USBTMC protocol. We rely on the VISA engine to create a stable overlayer on the USBTMC but if one does not want to use the VISA engine, it is of course possible to address the USB port directly at a USBTMC level. I will contact you to discuss further the possible approaches for the driver implementation you plan.

Hi, I have 3 of these products and am trying to use them for prolonged testing purposes, > 1000Hrs constant use. I find them very easy to set up and use, but I have found that they constantly crash. I am using a Labview 2009 program, based on your supplied Labview example code, which seems to work fine most of the time. However, I am getting sporadic crashed of 1 or more power meters which require a power down to fix. The code is running under Windows 7, do you know of any issues with this combination?

a response from Julien at Thorlabs: Thank you for your feedback. Several PM100USBs can be connected to the same hub. We actually provide a small utility software that allows to readout up to 8 PM100USB simultaneously. This utility can be downloaded from the software page of the PM100USB. Concerning the Iphone compatibility, the PM100USB software is entirely NI VISA based, which is as of now unfortunately not compatible with Iphones yet.

I was wondering if you have given any thought to making a PM100USB App for the iPhone etc. Our company currently does not provide smartphones or tablets to its employees but you can kind of see where things are heading... On a related topic, we have one of these, could I connect multiple PM100USBs to a single USB port via a USB hub? Mike

The S170C Microscope Slide Power Sensor Head is a silicon photodiode sensor designed to measure the power at the sample in microscopy setups. The silicon photodiode can detect wavelengths between 350 nm and 1100 nm at optical powers between 10 nW and 150 mW. The sensor head's 76.0 mm x 25.2 mm footprint matches that of a standard microscope slide and is compatible with most standard upright and inverted microscopes.

The photodiode has an 18 mm x 18 mm active area and is contained in a sealed housing behind a neutral density (ND) filter with OD 1.5. A 20 mm x 20 mm indentation around the surface of the ND filter is sized to accept standard microscope cover slips. An immersion medium (water, glycerol, oil) may be placed in this well directly over the ND filter, or a cover slip may be inserted first to simplify clean up. The gap between the photodiode and the neutral density filter has been filled with an index matching gel in order to prevent internal reflections from causing significant measurement errors when using high NA objectives with oil or water.

The bottom of the sensor housing features a laser-engraved grid to aid in aligning and focusing the beam. In standard microscopes, the grid can be used for beam alignment before flipping the sensor head to face the objective for power measurements. In inverted microscopes, turn on the transmitted illuminator to align the grid on the detector housing with the beam, thereby centering the sensor in front of the objective. Alternatively, the diffusive surface of the ND filter can be used as a focusing plane.

Sensor specifications and the NIST- and PTB-traceable calibration data are stored in non-volatile memory in the sensor connector and can be read out by the latest generation of Thorlabs power meters. The S170C power sensor is compatible with the PM100D, PM100A, PM100USB, PM200, and PM320E power meters. We reccomend yearly recalibration to ensure accuracy and performance. Calibration may be ordered using the CAL1 recalibration service available below. Please contact technical support for more information.

The complete set of specifications are presented on the Specs tab above. Thorlabs also offers a Microscope Slide Sensor Head with a thermal sensor; the full presentation can be found here.

S142C and S120-FC Fiber Adapter

S142C with the S120-FC Fiber Adapter (Included)
  • For Measurements Independent of Beam Shape and Entrance Angle
  • Integrating Sphere Design Acts as a Diffuser with Minimal Power Loss
  • Ø5 mm, Ø7 mm, or Ø12 mm Input Aperture
  • Removable S120-FC Fiber Adapter (FC/PC and FC/APC) Included
  • Compatible Fiber Adapters: S120-xx Series and S140-BFA Bare Fiber Adapter
  • Compatible with the PM200, PM100D, PM100USB, PM100A, and PM320E Consoles

These Integrating Sphere Photodiode Power Sensors are the ideal choice for power measurements independent of beam uniformity, divergence angle, beam shape, or entrance angle, making them excellent for use with fiber sources and off-axis free space sources.

Our integrating spheres are designed for wavelength ranges from the visible through the NIR. Sensor heads for use between 350 and 2500 nm use a single Ø1" or Ø2" sphere made from Zenith® PTFE and feature a black housing to minimize reflected light around the entrance aperture. These sensors use either a silicon photodiode for detection in the 350 - 1100 nm range or an InGaAs photodiode for detection in the 800 - 1700 nm, 900 - 1650 nm, or 1200 - 2500 nm wavelength range.

The S180C integrating sphere for 2.9 - 5.5 µm uses two connected, gold-plated Ø20 mm spheres, with an entrance port in the first sphere and a port for the MCT (HgCdTe) detector located in the second sphere. Compared to single-sphere designs, the two-sphere configuration improves device sensitivity by minimizing the internal sphere surface area while still effectively shielding the detector from direct illumination. This design reduces the effect of input angle, divergence, and beam shape on the measurement result by effectively shielding the photodiode without the use of a baffle or other shielding mechanism.

The integrating spheres below feature large Ø5 mm, Ø7 mm, or Ø12 mm apertures, externally SM1-threaded (1.035"-40) front connections, enhanced shielding against electromagnetic interference, and an over-temperature alert sensor. Because of the large active detector areas of these sensors, the included S120-FC fiber adapter can be used with FC/PC- or FC/APC-terminated fiber. The externally SM1-threaded adapter can be removed using a size 1 screwdriver to place components closer to the window. NIST-traceable data is stored in the sensor connector.

The S401C High-Sensitivity Thermal Sensor is designed for detecting broadband optical powers from 10 µW to 1 W sources with a resolution of 1 µW. The broadband coating used on this thermal sensor offers high absorption at wavelengths between 0.19 and 10.6 µm (shown in the plot below and to the right), which makes the sensor ideal for use with aligning and measuring Mid-IR Quantum Cascade Lasers (QCLs).

This sensor uses a thermal volume absorber, as these typically have significantly higher responsivities than thermal surface absorbers for detecting very low power levels and short (ns) pulses. However, this improvement usually comes at the expense of response time. The S401C sensor provides the best of both worlds, as it offers a similar response time to our fastest surface absorber thermal sensors (<1 s) without sacrificing the sensitivity needed for low power measurements.

The sensor aperture size of Ø10 mm allows easy alignment and measurement of laser sources with large spot sizes. The sensor also includes a removable, externally SM1-threaded (1.035"-40) adapter, which is held to the front of the sensor by two Philips-head screws. This adapter allows the sensor to be used with our Ø1" lens tubes, our fiber adapters (sold below), and the included, internally SM05-threaded (0.535"-40) light shield, as shown in the photo above and to the right. For use in particularly tight spaces, the adapter can be removed to reduce the thickness from 18.5 mm to 15 mm. The connector stores NIST-traceable calibration curves for the sensor.

Thermal Sensors for Excimer and YAG Lasers

Thermal Sensor Absorption
Click to Enlarge

These absorption curves are shown over a broader wavelength range than the sensors' operating ranges. See the table below for the operating wavelength range of each sensor.
For Excimer and YAG Lasers
  • For Optical Power Measurements of Excimer (S350C) and YAG (S370C and S470C) Lasers
  • Ideal for Applications with High Peak Powers
  • High-Sensitivity Version (S470C) Ideal for High-Peak-Power Pulses with Low Average Power
  • Compatible with the PM200, PM100D, PM100USB, PM100A, and PM320E Consoles

The S350C, S370C, and S470C Thermal Sensors are designed for high-peak-power pulsed laser sources. All of these units are post-mountable for free-space applications and feature NIST-traceable data stored in the sensor connector.

S350C
The S350C sensor features a Ø40 mm aperture and a 40 W max power (CW). It is designed for Excimer lasers and other applications that require measuring high-power, large-spot-size lasers.

S370C and S470C
The S370C and S470C are designed for YAG lasers. Both incorporate a Schott glass absorber on top of the thermal absorber; this glass layer allows them to detect pulses with high peak powers. The S370C features a large Ø25 mm aperture ideal for large-spot-size beams, and is compatible with average powers from 10 mW to 10 W (CW).

In comparison, the S470C has a smaller aperture of Ø15 mm and a lower max average power of 5 W. However, the S470C's smaller absorber decreases the response time to <2 s, and it has a thermal detector that can measure average powers down to 100 µW. With a housing size of only 45 mm x 45 mm x 18 mm, this thermal sensor head is also the most compact of our specialized thermal sensor heads for use with high-power lasers.
