Thermopile Sensor, High Peak Power, 50 W, 17.5 mm, 0.24-2.2 µm

The 919P-050-18HP is a thermal sensor with a special coating for high energy density pulsed laser beams, measuring up to 50W continuously. Its PF absorber type (with diffuser) covers the wavelength range 240 to 2200 nm - 2.2 µm. It has an aperture of 17.5 mm and can measure power from 140 mW to 50 W and single shot energy from 60 mJ to 200 J. It has a 1/4-20 tapped hole for post or plate mounting and includes a 2.25 inch long 1/2 inch diameter post with a 1/4-20 tapped hole on both ends.
