Gentec-EO UM9B-BL-L-D0 Pyroelectric Detector for laser power measurement up to 200 μW.

Measure low-power lasers at any wavelength with the BL absorber

The spectrally ultra-flat and broadband coating absorbs a very wide range of wavelengths. The very high absorptivity of our BL absorber guarantees a high sensitivity.

Can be used with broadband light sources

Wide dynamic range

Very low noise

Key Features

Very Low Noise Level

Noise levels of a photodetector, but with the large bandwidth of a pyroelectric

Very High Responsivity

Up to 20 000 V/W when using the analog power module (APM)

Very Large Bandwidth

From DUV to FIR thanks to pyroelectric technology

Smart Interface

Containing all the calibration data
