Radiometer

The Laser Power Radiometer IL1400A/SEL100FQ/K15 features a 100-mm² detector, flat response filter from 400 to 1060 nm, and an attenuator for measuring continuous laser light over a spectral range of 100 to 300 nW. It can zero out ambient light to isolate the laser beam for measuring visible and near-infrared lasers such as argon, HeNe, Nd:YAG, and imaged optical beams. Preprogrammed detectors require no setup, and the device, which runs on four AA batteries, can be equipped with an RS232 interface.
