Thermopile Sensor, 150 W, 26 mm, 0.19-11 µm, Fan Cooled

The 919P-150-26 Fan Cooled Thermopile Sensor is a general purpose thermal sensor measuring optical power up to 150 W. It's BB absorber type is spectrally flat and covers the wavelength range 190 nm to 11 µm. It has an active diameter of 26 mm and can measure continuous optical power from 50 mW to 150 W and single shot energy from 20 mJ to 100 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.

Spectrally Flat Response over a Broad Wavelength Range

The thermopile detector's response to the input laser beam is characterized by its absorption. The broadband BB type employed in this sensor has an excellent constant absorption throughout the 190 to 11 µm wavelength range.

Extensively Tested for Damage Threshold vs. Pulse Width

The 919P series thermopile detectors have been extensively tested for the damage threshold with a variety of lasers. You can trust our specifications and have your mind at ease.

NIST Traceability

This 919P thermopile sensor includes a DB15 connector and internal EEPROM for storing factory calibration data. It is calibrated at three different wavelengths ( 532 nm, 1070 nm, and 10.64 µm. Calibration of the thermopile detectors is recommended annually to assure NIST traceability.
