Datasheet(CN) Datasheet(EN) PC-Gentec-EO User's Manual UM-B User's Manual
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
