Air-cooled Thermopile Sensor, 150W, UV Coating

Manufacturer's part number :


Manufacturer Coherent


Description :

PM150X air-cooled thermopile model, surface absorbing sensor is intended for measurement of low to medium power pulsed and CW lasers from the 10 mW to 150 W power range. Convection cooling makes them simple to operate as well as mechanically compact. Product numbers ending in X are specifically optimized for use with excimer lasers operating in the ultraviolet (150 nm to 400 nm).

This PM150X sensor is compatible with FieldMate, FieldMaxII-TOP, FieldMaxII-TO, 3sigma, and EPM1000/2000 meters.
