The 100C-UAU thin profile thermal power laser sensor is 14.5 mm thick with mounting threads and has an 18 mm aperture. It can measure laser power from 60 mW to 4 W free standing and 100 W when heat sinked. It has the spectrally flat broadband coating covering the spectral range from 0.19 to 11 µm. It is connected via cable to a separate circuit board with USB output.
