Thorlabs' C-Series Thermal Power Meter Sensors are designed for the 100 µW to 200 W power range and the 190 nm to 25 µm wavelength range. Thermal sensors generally offer wider wavelength and power ranges but lower resolution and a considerably longer response time than a photodiode sensor. These sensors are well suited for use in a wide range of applications, particularly those requiring a flat spectral response and detection of low to mid power ranges. The S322C is designed for high optical powers up to 200 W (250 W for an exposure less than 2 min). The S350C and S370C are optimized for special laser applications (i.e., Excimer and YAG Lasers), which need specific features for best results. The S305C sensor has a very compact footprint of just 40.7 x 40.7 x 18 mm (1.6" X 1.6" x 0.71"). It is designed for applications where space and accessibility are at a premium.
Compatibility and Calibration
All sensors are connected to the power meter console via the C-Series connector, which offers quick sensor exchange. These sensors are compatible with power meter consoles with C-Series connectors only, including the PM200, PM100D, PM100A, PM320E, and PM100USB (see the Power Meter Compatibility Chart for details).
The sensors can be mounted on our 1/2" Mounting Posts using an M4 or M6 tap; a 60 mm or 75 mm tall post is included with each sensor (see the Specs tab for details). Additionally, the S305C, S310C, S314C, and S322C sensors are compatible with our 30 mm cage standard. Please note that post holders are sold separately.
Each sensor head is individually calibrated and is shipped with a NIST- and PTB-Traceable Calibration Certificate. The calibration and identification data is stored in the connector of the sensor and is downloaded automatically to the connected power meter console.
Thorlabs offers specific recalibration services for all our thermal power sensors. To ensure accurate measurements, we recommend recalibrating the sensors annually. Please contact our tech support team for recalibration information and pricing. We also offer expedited sensors calibration.
Sensor Upgrade Service
All C-Series Sensors are incompatible with old power meter consoles with non-C-Series connectors. We offer a sensor upgrade service if you want to use your existing sensors with a new power meter console with C-Series connector. Note: upgraded sensors will be incompatible with old power meter consoles with non-C-Series connectors. Please contact our tech support team for details.
