Coherent Beam Position Thermopile Power Sensors 1174270 | 100mW-20W

Product Details The LM-20 is designed for embedded use and must be mounted on a heat sink. Thermopile Detector Element for High Power Measurements Measure Beam Position on Detector Surface ISO 17025 Certified Coherent Beam Position Sensing Thermopile Power Sensors are all-purpose sensors designed to measure the average power or energy of a wide variety of continuous wave or pulsed lasers. Coherent Beam Position Sensing Thermopile Power Sensors utilize a quadrant thermopile detector disk to sense the position of the laser beam on the detector surface while measuring the laser power. Coherent thermopile sensors can operate across a wide range of input powers, and do not saturate. Note: The LM-20 is designed for embedded use and must be mounted on a heat sink.
