The 919P-050-26 General Purpose Thermopile Sensor measures laser power up to 50 W. Intermittently, it can handle up to 150 watts for 1.5 minutes or 100 watts for 2.2 minutes. It's spectrally flat coating covers the wavelength range 0.19 - 11 μm. It has an active diameter of 26 mm and can measure power from 40 mW to 50 W and single shot energy from 20 mJ to 30 J. It has a 1/4-20 tapped hole for post or plate mounting and comes with a 1/2 inch diameter post.
Calibration of the thermopile detector is required annually to assure NIST traceability.
