Broadband 15 kW Water-Cooled ?48 mm Thermopile Power Sensor

The BND-15K-D48CP is a water cooled thermal power sensor is designed for very high powers with a ?48 mm aperture. It can measure power from 100 W to 16,000 W. It has a deflecting cone and annular absorber that withstands high power densities to 10 kW/cm2. It covers the spectral range from 266 nm to 10.6 μm.

Thermal Power Sensor Features:

1. Broadband 266 nm to 10.6 μm absorber with beam deflector
2. Water-cooled for 0.1 to 16 kW average power measurement
3. Deflecting cone and annular absorber for power densities to 10 kW/cm2
4. 48 mm diameter aperture
5. High linearity,sectional calibration is not required;
6. Multi-layer cone reflection design,reduce the power density on the disc and improve the stability and reliability;
7. High absorption;

8. V-Groove is optional.
