The 30K-W-BB-74 is a water cooled thermal power/energy laser measurement sensor for high powers with a 74mm aperture. It can measure power from 100W to 30,000W. It has a deflecting cone and annular absorber that withstands high power densities to 10kW/cm2. It covers the spectral range from 0.8 - 2 and 10.6μm. The sensor comes with a standard 10 meter cable for connecting to a meter or PC interface.
