Ophir® Ariel, a self-contained, ultra-compact laser power meter for measuring high power industrial lasers up to 8KW. Designed for OEM and end-user applications in closed and confined spaces, such as additive manufacturing, 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 a wide range of wavelengths, including 440-550nm green and blue lasers, increasingly popular in copper welding; 900-1100nm fiber lasers, used in most metal processing; 10.6µm CO2 lasers; and 2.94µm medical lasers. Unlike competitive offerings, the Ariel power meter provides a range of features for more flexible measurement options: it measures a wider range of wavelengths; can be operated in continuous or short exposure mode; can be used with or without a diffuser for higher power densities; delivers 3 to 5 times faster reading times; and can be operated stand-alone or wirelessly.
