1 Optical Power & Energy Meters S120C Photodiode Sensor Our compact USB Power Meters can be controlled by a PC (not included) running Thorlabs power meter monitor GUI. TSPTH Temperature Sensor Our Wireless Power Meters can be controlled with an ipad (not included) running our Power Meter app. PM400 Touchscreen Console Measure Optical Power and Energy Thorlabs extensive line of optical power and energy meters includes power meter consoles, a large selection of sensor heads, and complete allinone power meters. When combined with our sensor heads that use Cseries connectors, our consoles can provide calibrated (NISTtraceable) optical power and energy measurements from the UV to the IR. Cseries sensors are available in photodiode, thermal, or pyroelectric formats enclosed in a range of housings, including ultraslim sensor heads for measurements in tight spaces and microscopeslide sensor heads for use with imaging systems. We also offer three styles of complete power meters. Our wireless power meters include a small OLED screen for local control and incorporate Bluetooth technology to support remote operation through free apps for Android or ios. Fiber power meters feature a rugged design and an internal sensor for measurements in the lab or the field, while compact USB power meters can be connected to the USB port of any computer and controlled via Thorlabs Power Meter Software.

2 Optical Power and Energy Meter Consoles Thorlabs Optical Power and Energy Meter Consoles are designed to display calibrated measurements when used with our photodiode, thermal, or pyroelectric Cseries sensors. They are available in a variety of formats from the PM100A analog needle console to the PM400 digital touchscreen console. Digital Touchscreen Power and Energy Meter Console u Projected Capacitive Touchscreen with Color Display u Over 30 Compatible Optical Power and Energy Sensors u Supports Spectral Calibration and Attenuation Correction u Inputs for Temperature and Humidity Sensors u USB 2.0 Interface for Remote Control, Data Transfer, and Charging The PM400 features advanced spectral correction capabilities that allow the user to save and apply calibration and attenuation correction files. The capacitive touchscreen enables fast access to measurement settings, while the use of multitouch technology allows data displays to be zoomed and scrolled with hand gestures. PM400 Digital Power and Energy Meter Console u Ideal for Accurate Power and Energy Measurements u Over 30 Compatible Optical Power and Energy Sensors u Large Liquid Crystal (LC) Display with Multiple Display Options u External 2 GB SD Memory Card u LongLife Internal LiPolymer Battery PM100D The PM100D digital console features a 4 backlit display with measurement screens that include a numerical readout, simulated analog needle, bargraph, trendgraph, and statistics. A data acquisition mode allows power measurements to be recorded and saved to the included SD Memory Card. Console with Analog Needle and LCD Screen u Ideal for Fine Tuning of CW and Pulsed Lasers u Over 20 Compatible Optical Power and Energy Sensors u Combined Analog and Digital Power Meter Console u Fast Mechanical Needle with 3 Scales u Graphic Liquid Crystal (LC) Display The PM100A console is capable of providing absolute or relative measurements of optical power when used with one of our photodiode or thermal sensors. The analog needle sits above three printed scales, while an LCD screen displays four different readouts: absolute power, relative power, statistics, and a configuration menu. PM100A Note that this console is not compatible with our pyroelectric energy sensors.

3 DualChannel Power and Energy Meter Console u Two Programmable Channels Monitor Math Functions Ratio Difference Attenuation Linear and Log Values u Large 4.4" LC Display u Suitable for a Variety of Applications The PM320E dualchannel console is ideal for precise optical measurements, laser and photodiode characterization, lifecycle characterization, and more. The dualchannel design enables differential and ratiometric measurements. PM320E USB Power and Energy Meter Interface u Applicable for Measurements that do Not Require Regular Readouts u Very Compact Device for Power and Energy Measurements u Same Functionality as the PM100D Console The PM100USB is an extremely compact solution for cases where a console with a readout screen and controls is not needed. This interface provides the functionality of the popular PM100D, but the readout and interface controls are provided remotely via a PC (not included) running our Power and Energy Meter Software.

Select sensors are offered from stock in our Compact USB Power Meters. To order other sensor heads in this format, please contact techsupport@thorlabs.com. b. Of the Photodiode Sensor. Actual response time will be limited by the update rate of the console. c. Response time is limited by the sensor material. Thorlabs' thermal sensor and power meter consoles are designed so that the incident power can be determined after a single sensor time constant, which results in a response time lower than the sensors natural response time. d. Maximum Exposure Time of 2 Minutes e. With Intermittent Use (Maximum Exposure Time of 20 Minutes) f. 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.
