Thermopile Sensor, Slim, 20 W (4 W Standalone), 12 mm, 0.19-11 µm

The 919P-020-12 Thermopile Sensor is a general purpose laser power sensor measuring laser power up to 20 W, when it is heat sinked to chassis. It can handle up to 4 watts when it is used free standing. Its BB absorber type is spectrally flat and covers the wavelength range 190 nm to 11 µm. It has an active diameter of 12 mm and can measure power from 10 mW to 20W and single shot energy from 6 mJ to 10 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.
