Thorlabs - Pyroelectric Energy Sensors
Thorlabs` Pyroelectric Energy Meter Sensors are sensitive to wavelengths from 185 nm to 25 µm and together span the energy range from 10 µJ to 15 J. All of these sensors provide a flat response over a large wavelength range. The ES220C and ES245C feature a ceramic coating that is specifically designed for lasers with high energy densities requiring high damage thresholds.
- For Pulsed Applications Over a Wide Wavelength and Energy Range
- Individually Calibrated with NIST- and PTB-Traceable Certificate of Calibration
- BNC Connector for Direct Use with Oscilloscopes
- Compatible with our C-Series Power Meters via BNC to C-Series Adapter
- Electrically Isolating Post Adapters Included
Compatibility
All the sensors listed here are compatible with the PM400, PM100D, PM320E, the PM103 series, and PM100USB. Please note that they are not compatible with the PM100A. Alternatively, the sensors can be connected directly to an oscilloscope with a 1 MΩ input resistance via the BNC connector. To accommodate higher repetition rates when connected to oscilloscopes, the load resistance can be reduced. Calibration value for both 1 MΩ and 100 kΩ resistors are given with the sensor certificate of calibration.
The bottom of the sensor head has an 8-32 mounting hole. Since the heads are very sensitive to ground loops and electrical noise, we recommend attaching the heads to the included electrically isolating post adapters, which provide direct compatibility with either imperial or metric Ø1/2" (Ø12.7 mm) Posts. The ES120C and the ES220C can also be mounted to our 30 mm Cage System via the four 4-40 threaded holes on the front, although this mounting option does not provide electrical isolation.
Calibration
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 BNC to C-Series adapter, shown in the image to the right, and is downloaded automatically when connected to the console.
Recalibration Services
Thorlabs offers recalibration services for our pyroelectric energy sensors. To ensure accurate measurements, we recommend recalibrating the sensors annually. Pyroelectric energy sensors returned for recalibration or servicing must include the separate BNC to DB9 adapter, which contains the sensor EEPROM. To order this service for your sensor, scroll to the bottom of the page and select Item # CAL-THPY. Recalibration of a single-channel power and/or energy meter console or interface is included with the recalibration of a sensor at no additional cost.
