Coherent PM150-50C water-cooled laser power sensor Description：

Datasheet

This PM150-50C sensor is a water-cooled laser power sensor intended for measuring lasers up to 150W with water, and up to 80W without water for short durations (up to five minutes at a time). This sensor model is also very commonly used for individual long-pulse energy measurements up to 150J.The sensor is terminated in a SmartSensor DB25 cable and is directly compatible with all power meters in the catalog. A USB-direct model (PN 1168348) is available.

Water-cooled thermopile sensor 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.
