The 919P-250-35 Fan Cooled Thermopile Sensor is a general purpose thermal sensor measuring optical power up to 250 W. It's spectrally flat coating covers the wavelength range 0.19 - 11 μm. It has an active diameter of 35 mm and can measure continuous optical power from 150 mW to 250 W and single shot energy from 50 mJ to 300 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.
