For a full list of available kits, see the table to the right.

All three consoles have a USB 2.0 connection that allows them to be controlled remotely using a PC with the Optical Power Meter software package installed (see the Software tab for details).

PM100A Analog Console
Suitable for both absolute and relative power measurements, the PM100A analog power meter console features an analog needle display and a supplemental LCD screen. The analog needle is ideal for relative power measurements and for watching small power fluctuations. The PM100A is compatible with all C-Series photodiode sensors and thermal sensors; it is not compatible with our pyroelectric energy sensors. The PM120VA power meter kit includes the PM100A console and power cables, an S120VC sensor, and a USB flash drive with the software package preloaded. For more information on the PM100A analog console features, see the Specs and Display tabs above or visit the full web presentation.

PM100D Digital Console
The PM100D digital power and energy meter console features a menu-driven control panel, 4" backlit display, and SD card slot for storing data. Measurements screens include a numeric readout useful for standard power and energy readings, a simulated analog needle, graphs of power measurements over time, and a statistics view. Additionally, the PM100D console has a tuning mode that provides audio feedback for use when the detector is not within visual range. See the PM100D Display tab for more information. The console is compatible with all our C-Series sensors for power or energy measurements, including our pyroelectric energy sensors, and includes a USB flash drive with the software package preloaded. For more information on the PM100D digital console features, see the Specs and Display tabs above or visit the full web presentation.

PM400 Touchscreen Digital Console
The PM400 touchscreen digital power and energy meter console features a 4.3" display with multi-touch technology. Capacitive buttons on the front of the unit enable fast access to set the source wavelength or spectrum, a delta mode that shows the change in power from a user-selected set point, the zeroing function, and device main menu. In addition to pre-programming source wavelengths or spectra for calibrating measurements, users can enter and save up to twelve attenuation values or data files to correct for effects that external devices (such as filters or beamsplitters) may have on the power measurement.

A 14-pin auxiliary input allows users to connect their own humidity and temperature sensors as well as access four programmable I/O ports for controlling shutters, interlock devices, laser warning lights, and other common lab devices (see the Pin Diagrams tab for pin descriptions). Alternatively, a 2.5 mm stereo (3P) jack accepts the TSP-TH thermistor temperature probe. Like the PM100D, this console is compatible with all our C-Series sensors. For more information on the PM400 touchscreen digital console features, see the Specs and Display tabs above or visit the full web presentation.

Additional Power Meter and Sensor Options
The power meter consoles and sensors in these kits can also be purchased individually. Additionally, Thorlabs offers self-contained wireless power meters, designed for both handheld operation and remote control via Bluetooth or USB, and compact USB power meters, designed to be operated via software control on a PC.

The Front Panel of the Touchscreen Power Meter Console

Touchscreen Power Meter Console Front Panel

Thorlabs' PM400 Power Meter Console features a front panel with several key elements, as shown in the photo to the right. The projected capacitive touchscreen and buttons are sensitive enough to allow smooth operation even when the user wears cotton, latex, or nitrile gloves, but durable enough to be cleaned with standard screen cleaning solvents.

  • Capacitive Touchscreen: The capacitive touchscreen allows the user to control the console functions with finger taps and swipes. Features include numerical displays of power and energy measurements, logging of long-term measurements, settings for a calibration wavelength or a preset attenuation value, and temperature monitoring. The user can switch measurement views by swiping one finger over the screen to the left or right, or by tapping the window icon in the lower right corner of the screen. More details on the measurement options are provided below.
  • Spectral Correction Button: This button opens a screen where the user can quickly select or save up to 12 measurement wavelengths. The PM400 will use this wavelength setting in conjunction with the calibration data recorded in the connector of Thorlabs' power and energy sensors in order to provide a calibrated optical power or energy reading. The selected wavelength is displayed above the button.
  • Delta Mode: In delta mode, the console will display the power or energy relative to a user selected setpoint. Pressing this button saves the current power or energy reading as the reference value, and subsequent measurements will be displayed as the difference between the actual value and the reference. The reference value is displayed above this button when Delta Mode is active. 
  • Zeroing: Quickly set the current power or energy value as the zero point for subsequent measurements. The measured power or energy when the console is zeroed will be displayed above the Zero button.
  • Main Menu: This button provides quick access to the main menu. From here, the user can access a submenu to set the parameters for long-term power measurements, device settings, the file manager, sensor info, and the laser calculator. Details are provided below.

Additional Features
In addition to allowing users to select different measurement modes and settings, the PM400 incorporates other features to allow users to customize the interface.

  • Language Settings: English, French, German, and Chinese can be selected.
  • Display Brightness and Contrast: In addition to adjusting these settings, the user can choose whether to have the display show white text on a black background, or black text on a white background.
  • Laser Tuning Sound: The console plays an audible tone to aid in identifying when peak power is achieved while tuning a laser. The console will beep repeatedly, with the frequency of the beep increasing as the measured power increases.
  • Programmable I/O Ports: The PM400 features four programmable I/O ports for controlling shutters, interlocks, laser warning lights, etc.

  • Many, but not all, of Thorlabs' compatible optical power sensors have an internal temperature sensor. This subpanel display option is only available if this internal temperature sensor is detected by the PM400.

The numerical display shows a digital measurement of the power or energy with a bar graph along the bottom. The orange and blue triangles on the bar graph show the min and max values detected during the measurement. To reset the min and max values, press the reset button on the front panel. The six rectangular subpanels immediately above the power or energy measurement are configurable displays, allowing the user to select which parameters to view. The Subpanel Display Options table provides a summary of available settings for each style of detector.

Simulated Analog Needle

Power Meter Analog Needle

Measurements can be viewed with a simulated analog needle. The orange and blue marks are indicators for the max and min measured power, and the scale can be zoomed by a factor of 10. Icons down the side of the screen allow the user to set the bandwidth, adjust the resolution of the digital value at the bottom of the display, change units, adjust the display update rate or change screens.

Graph View

Power Meter Data Logging

In the graph view, the user can monitor the optical power or energy of a source as it changes over time. A second, optional display can be added that shows the readout from a connected temperature sensor (the upper graph in the screenshot above). Icons on the side of the window allow the user to start and stop the measurement, scroll through the data, and open the folder where the measurement is saved.

Statistics Display

Power Meter Data Statistics

In the statistics display, the user can start a sequential measurement. The sample rate and duration can be adjusted from the Capture Settings screen, accessible from the main menu. The bottom bar of the display shows the number of measurements taken, total elapsed time since the measurements were started, and the measurement interval. The main part of the display shows statistics for the accumulated measurements, including the minimum, maximum, mean, and standard deviation.

Spectral Correction

Spectral Correction

This mode can be entered by pressing the λ symbol on the front panel. The unit can store up to 12 preset spectral correction entries, editable by the user. In their simplest form, these entries can consist of a single user-entered wavelength that will be used in conjunction with the NIST-traceable calibration data from a Thorlabs' sensor to produce a calibrated power measurement. Alternatively, each entry can be a .csv file with the source spectrum that has been uploaded and saved. When a spectral correction entry is selected, the entry name will be displayed in the field above the spectral correction button.

Attenuation Correction

Attenuation Correction

External devices within a setup, such as a filter or beamsplitter, may be needed to attenuate the signal being measured. The attenuation correction function allows the PM400 to display a power reading that accounts for these sources of attenuation. Attenuation values can be assigned as a multiplier (e.g. x2), in percent, in dB, or in OD (optical density). Alternatively, complete filter transmission curves can be uploaded and saved. Up to 12 different attenuation settings can be programmed and stored.

Main Menu

Main Menu

The PM400 main menu allows access to device features including the screen brightness, the menus to set the parameters for power, energy, and temperature measurements, a screen for calculating laser pulse characteristics, and a unit converter.

Capture Settings

Capture Settings

This screen allows the user to set the parameters for taking data. User-selectable settings include manual or automatic data acquisition, the exposure time, the number of samples, and the capture interval. It also allows the temperature logging parameters to be set. Once all of the settings are selected, this screen will return an estimated file size so that the user can ensure there is enough free memory on the device. In the case of manual operation (the user manually starts and stops the measurement), the estimated output file size will be the rate at which memory is used up as the data is collected.

Sensor Measurement Settings

Measurement Settings

This screen allows the user to view sensor-dependent content, adjust common settings such as wavelength, attenuation, mode, etc., and enter beam parameters.

Temperature Sensor Settings

Temperature Measurement Settings

If an external temperature sensor is hooked up to the PM400, the user can adjust the parameters here.

Laser Calculator and Unit Converter

Laser Calculator

The PM400 has several calculators. The laser calculator screen allows the user to calculate laser beam parameters based on available inputs. A unit converter provides quick conversions between Watts and dBm or between wavelength, frequency, wavenumbers, and photon energy.

Optical Power Monitor GUI Software for Touchscreen, Handheld, and USB-Interface Power Meters

Features

  • Operate up to Eight Power Meters Simultaneously
  • Record and Analyze Measurements in Real Time
  • Intuitive Analog Display and Graphing Modes
  • Configurable Long-Term Data Logging
  • Compatible with USB and Bluetooth® Connections

The Optical Power Monitor software GUI enables seamless control of up to eight power meters that are connected via USB or Bluetooth® wireless technologya. The latest software, firmware, drivers, and utilities for these power meters can be downloaded here

Multiple data measurement and analysis functions are integrated into the GUI package. The interface offers a user-friendly design with minimal use of color and low brightness that is ideal use in dark lab environments while wearing laser safety glasses. Measured data can be displayed in real time as a simulated analog needle, digital values, line graph, or bar graph. Continuously logged and short-term measurements can be recorded for data viewing and analysis at a later point. A built-in statistics mode analyzes measured data and continuously updates to reflect new measurements within the pre-determined measurement period.

The Optical Power Monitor software package installs the GUI, which then can be used to control the touchscreen, handheld, or USB-interface power meters. Firmware updates for supported power meters are also available. Programming examples and drivers for interfacing with our power and energy meter consoles using LabVIEW, Visual C++, Visual C#, and Visual Basic are installed with the software; refer to the manual for details. 

Please note that the Optical Power Monitor Software uses different drivers than the Power Meter Utilities Software and Thorlabs recommends using the new driver TLPM.dll. For users who wish to use the legacy Power Meter Software or use custom software designed using the older PM100D.dll driver, a Power Meter Driver Switcher program is included for easy swapping of the installed driver between the two versions. 

a. The PM160, PM160T, and PM160T-HP power meters are equipped with Bluetooth® connections.

Thorlabs offers a wide selection of power and energy meter consoles, ranging from the touch screen PM400 to the analog PM100A. Key specifications of all of our power meter consoles are presented below to help you decide which device is best for your application. We also offer self-contained wireless power meters.

When used with our C-series sensors, Thorlabs' power meter consoles recognize the type of connected sensor and measure the current or voltage as appropriate. Our C-series sensors have responsivity calibration data stored in their connectors. The console will read out the responsivity value for the user-entered wavelength and calculate a power or energy reading.

  • Photodiode 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. The photodiode's responsivity is wavelength dependent, so the correct wavelength must be entered into the console for an accurate power reading. The console reads out the responsivity for this wavelength from the connected sensor and calculates the optical power from the measured photocurrent.
  • Thermal sensors deliver a voltage proportional to the input optical power. Based on the measured sensor output voltage and the sensor's responsivity, the console will calculate the incident optical power.
  • Energy sensors are based on the pyroelectric effect. They deliver a voltage peak proportional to the pulse energy. If an energy sensor is recognized, the console will use a peak voltage detector and the pulse energy will be calculated from the sensor's responsivity.

The sensors are also capable of displaying the current or voltage delivered by the sensor. Alternatively, a current or voltage equivalent to the measured value is provided at the analog output.

  • Up to 300 Hz. The refresh rate is limited by the PC used to operate the PM100USB power meter interface, as it does not have a built in display.
  • These are the measurement views built into the unit. All of our power meter consoles except the PM320E can be controlled using the Optical Power Monitor software package. The PM320E has its own software package.
  • The PM100USB power meter interface does not have a built-in monitor, so all data must be displayed through a PC running the Optical Power Meter Software.

Hello, I'm using the PM120D pack (with S120C photodiode) for measuring an light intensity in function of time. I'm wondering if I can have a response time on the order of microsecond with the analog output. Thank you, Anatole HELIOT
shallwig  (posted 2016-04-27 10:41:24.0)
This is a response from Stefan at Thorlabs. Thank you very much for your inquiry. The analog output Bandwidth is DC-100 kHz dependent on the sensor. For the photodiodes sensors you can find the output bandwidth dependent on the current range in the manual on page 68 https://www.thorlabs.com/thorcat/17600/PM100D-Manual.pdf . I will contact you directly to check your application in more detail.

A response from Julien at Thorlabs: Dear Martin, I am really sorry about this inconvenience. We will ship you a replacement immediately. Concerning your question about the quality control, we do check each power meter individually before shipment. I unfortunately do not know what the exact problem with your console is but I assume something must have happened during the shipment. We will inspect the unit as soon as we have it back and take the appropriate measures to prevent such issue from happening again. I will contact you directly to sort out the shipping details for the replacement.

I have unpacked my PM204 (consists of a PM200 and a S120VC) but it is not reading anything. The measured value remains inf as well as the minimum and maximum value. Also in the applied software I don`t see any reading (value remains 0 or ---). I have auto ranging on an tried with several light conditions. In the software an indicator shows A (waiting for new measurement value)(in the left top corner) while I expect sometimes a T of "trigger". The detector itself is ok since it is functioning on a PM100D console. I have attached also a second detector (S155C)on the PM200 without success. I have checked for firmwareupdates but there are non available on the website. I can not find any reset functions or trigger-arm functions in the manual nor in the software. Did anybody check the console before chipping? That must be since a callibration sheet was shipped with it?!?! How do I fix it? Martin

Handheld Power Meter with iPad
Click to Enlarge

The PM160 wireless power meter, shown here with an iPad mini (not included), can be remotely operated using Apple mobile devices.

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 (Not Compatible with PM100A)
  • 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.
  • Typical natural response time (0 - 95%). Our power consoles can provide estimated measurements of optical power on an accelerated time scale (typically <1 s) when the natual response time is approximately 1 s or greater. As the natural response times of the S415C, S425C, and S425C-L are fast, these do not benefit from accelerated measurements and this function cannot be enabled. For more information, see the Operation tab here.
  • With intermittent use: maximum exposure time of 20 minutes for the S401C, otherwise maximum exposure time is 2 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.

  • The S130C sensor features a sliding neutral density filter.

Each kit includes our PM100D or PM400 console, a S130C photodiode power sensor, and a post assembly, consisting of a BA2 base, PH2 post holder, and TR2 Ø1/2" post. The kit's slim sensor head is ideal for use in tight spaces as it is only 0.2"
(5 mm) thick at its sensor. A sliding neutral density filter extends the power range that the sensor can be used to measure. With the filter out of the beam path, the power detection range is
500 pW to 5 mW. With the filter in the beam path, power detection from 50 nW to 500 mW is possible; however, power levels below 5 mW should be detected without the filter in the beam path for optimal results. The filter's position is automatically detected and accounted for by the power meter console.
