Fan-cooled Thermopile Sensor, 300W, Broadband Coating, 50mm Aperture

Manufacturer's part number :


Manufacturer Coherent


Description :

PM300F-50 fan-cooled thermopile sensor allow for continuous power monitoring at 300 W with aperture diameter of 50mm. Forced-air, fan-cooled sensors enable measurement of higher powers than passively cooled sensors, and are an excellent choice for measuring high-power lasers when water-cooling is not possible. In conjunction with their compact size, ease of portability makes fan-cooled sensors particularly useful for field service or production test applications.

A compact wall-mount power supply provides the 12 VDC required to power the low-noise, brushless fan motor.
