Thorlabs’ Dual Channel PM320E Power and Energy Meter offers many feaures not found in handheld devices. It is ideal for precise optical measurements, laser and photodiode characterization, lifecycle measurements and many more applications in the lab and on the manufacturing floor.
The dual-channel design enables differential and ratiometric measurements. Intuitive manual operation with the large graphics display, compatibility to conventional photodiodes, and excellent remote capabilities enable easy system integration.
The PM320E is compatible with all Thorlabs Photodiode Sensors (dual-channel) and Thermal Sensors (single channel only) and allows the connection of unamplified anode or cathode grounded photodiodes with up to 10mA photocurrent and thermal elements with up to 100 mV output voltage.
Additionally the PM320E offers energy measurements with all Thorlabs Pyroelectric Energy Sensors (both channels). More information can be found in the Sensor Compatibility tab and the Power Meter Compatibility Chart.The PM320E is sold as a single benchtop device with the sensors available separately. Please see Thorlabs' complete line of sensors below.
Console Design The calibrated sensors connect via two sub-D connectors on the rear panel, which also provides two analog high bandwidth outputs to allow monitoring of each channel, plus the programmable analog output. Optional user-supplied photodiodes connect via two BNC inputs on the front panel, which feature switchable bandwidth and a programmable bias voltage. The input can be switched between the front and rear connectors. The additional BNC output is gain-and-function programmable. It provides an analog voltage proportional to the output of one of the channels or as a difference or ratio of the two power meter channels. The measurement resolution is 16 bit for all power ranges. The PM320E are controlled locally via the front panel, which features a large 240 x 128 pixel LCD display, or remotely via USB 2.0.
In addition to the console, the following comes with each purchase: Software CD ROM, LabVIEW™ and LabWINDOWS™ /CVI Driver Set, Certificate of Calibration, and Operation Manual.

*Compatible with Anode Grounded and Cathode Grounded photodiodes and bias voltages of 0 to ±10 V.
The PM320E 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 PM100D. 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.
Please see the Applications tab for common sensor arrangements. Please see the Power Meter Compatibility Chart for information about using new and old sensors with the PM320E and other Thorlabs power meters.
Power and energy density can 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 shown below. Utilizing the variety of sensors, the PM320E 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.
Additionally, the PM320E communicates with the sensor and accesses spectral response functions, time constants, and other information specific to the detector. The PM320E 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 PM320E 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 PM320E. Please contact our tech support team for details.
Sensor Head Compatibility Chart
Thorlabs has been expanding and improving on its power meter consoles and sensor heads over the past several years to meet the demanding needs of our customers. Sometimes this creates compatibility issues. The chart to the right shows compatible and incompatible sensors and consoles. A complete compatibility chart showing all Thorlabs' current and former generation sensors and consoles is also availalble here.
Many of Thorlab's power meter sensors are directly compatible (see S15xC Sensors) or can be made compatible with the use of the adapters listed below. The chart below shows all of Thorlab's sensors and the compatible fiber adapters. Note that there may be more than one adapter for each sensor. A complete list of compatible fiber adapters for all of Thorlabs' current and former generation sensors is available here. Contact tech support for any specific questions regarding these 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.
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' 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.
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.
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.
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.

a response form Julien at Thorlabs: Thank you for your inquiry! The PM320E can be in principle used with any thermopile detector or photodiode. The only physical limitation are the voltage and current readout ranges (100 nA - 10 mA and 1 mV - 1 V). The connector used are standard subD9 connectors. the detailed pin out of the connectors. For the use of custom Thermopile, it is further necessary to short pin 2 and 6 with a resistor of 10 to 15kOhms. You can find more detail about the exact procedure in the section 3.3.4 of the manual.

Could Power Meter(PM320E) work for other detectors such as Newport's photodiode detector (918D-UV OD3) and thermopile detector (818P-070-12)?
Thanks you.

Does this PM320 powermeter have an audio feedback feature(ie acoustic pitch related to power level)? This is very usefull to 'hear' a light signal fluctuation, or adjust a photodiode to the max.
I am currently having difficulty coupling 633nm or 850nm single mode fibers rapidly just by looking at the bargraph.

Thank you for your feedback. There is a .bas file installed with the driver for the PM300 series, and it can be found here: C:\Program Files\IVI Foundation\VISA\WinNT\include\PM300_Drv.bas
There is no example but normally, with this file, the programming and communicating in VB with the PM300 should be okay.

Response from Javier at Thorlabs to last poster: Thank you very much for contacting us. You can certainly use the S150C fiber coupled sensor with FC/APC connectors. The small beam deviation caused by the APC connector does not have any negative effects on the performance of the sensor.vPlease contact us at techsupport@thorlabs.com if you have any further questions.

Response from Javier at Thorlabs to cchipman: Thank you very much for submitting your request. The missing connector for the initialize.vi is related to a conversion problem between the different Labview versions. We will modify the software package so as to include a version of the initialize.vi that is compatible with all LabView versions. We will also include a small example VI. I will contact you directly to send you those files.

I am looking for an example program in LabVIEW just to start me out. For example, the PM300 Initialize VI does not have a Resource Name connector defined, it is present on the subVI but there is no connector for it. So how is it used? Also, the instrument handle out type does not match instrument handle in type. How does it work?
The PM100D has a simple example program, could you duplicate it with the PM300 VIs?

A black broadband or ceramic coating is used for low or high power measurements, respectively. Large sensor areas from Ø11 mm - Ø45 mm allow easy alignment. The energy sensors features BNC connectors for oscilloscope use, as well as standard power meter connectors which contain NIST and PTB-traceable calibration data.
