Coherent PM150-50XC Power Sensor Description：

Datasheet

This PM150-50XC sensor is a water-cooled laser power sensor intended for measuring lasers up to 150W, and up to 80W without water for short durations (up to five minutes at a time). It incorporates a UV absorber coating that is optimized for use at ultraviolet wavelengths. Spectral compensation is available from 157 nm to 1064 nm.

The sensor is terminated in a SmartSensor DB25 cable and is directly compatible with all power meters in the catalog.

Water-cooled thermopile sensor with UV coating for measuring pulsed & CW lasers between 300 mW and 150W. It can be used to measure 80W without water, intermittently, for up to five minutes.
