The 120K-W is a water cooled thermal power/energy laser measurement sensor for very high powers with a 200mm aperture. It has dimensions 520 x 545 x 750mm. The 120k-W laser power meter can measure power from 10,000W to 120,000W and is designed for a beam expanded to 100mm diameter to hit its deflecting cone and is calibrated at 1.07µm. Applications include laser weapon measurements and laser measurement for semiconductor lithography processes. The sensor comes with a 10 meter cable for connecting to a meter or PC interface
