USB-enabled Thermopile Sensor, 3W, with Position Sensing

Manufacturer's part number :


Manufacturer Coherent


Description :

LM-3 Thermopile sensor is a great all-purpose technology suitable for many lasers. LM-10 Thermopile sensor is used for measuring CW laser power, average power in pulsed lasers, and are often used to integrate the energy of long pulses. Thermopiles operate across a wide range of input powers, and unlike a photodiode-based sensor they will not saturate. LM-30 Thermopile sensor incorporate a quadrant thermopile detector disk that enables them to sense the position of the laser beam on the detector surface while measuring the laser power.
