Water Cooled 1000W Laser Power Measurement Sensors

Model: BND-1500W-D36

The BND-1500W-D36 thermopile sensor is a water cooled laser power and energy thermal sensor with a 36 mm aperture. It can measure optical power from 10 to 1500 W . It has the spectrally flat broadband BB coating and covers the spectral range from 266 nm-10.6 um. 

Features:
1.Measures laser power continuously, up to 1500W.
2.Highly linear, does not require sectional calibration.
3.Excellent absorption capability.
4.Available with 35mm apertures.
5.Water cooling feature.
6.Broadband 266 nm-10.6 umabsorber
7.Water-cooled for 15 to 1500 W average power measurement
