LaserCheck Laser Power Meter
Coherent’s LaserCheck™ is an affordable laser power meter for CW laser powers from 0.5µW to 1W across the wavelength range from 400 to 1064nm. LaserCheck is ultra-compact and can easily be carried in a pocket or tool kit. At higher powers, the silicon sensor is protected from saturation with a built-in optical attenuator, and all measurements are displayed on a 3-digit LCD screen. LaserCheck is microprocessor-controlled with wavelength correction, auto-ranging (µW or mW displayed), optical attenuator compensation, power overload warning and automatic shut-off.
