Designed for OEM and end-user applications in closed and confined spaces, such as additive manufacturing, metal cutting, and welding, the Ariel power meter is a robust, battery-powered device that requires no water or fan cooling and is small enough to fit in the palm of your hand. The system measures laser powers from 200mW to 8KW, and at a wide range of wavelengths, including 440-550nm green and blue lasers, increasingly popular in copper welding.
