Gentec-EO PH20-Ge-OD1-D0 Photodiode detector for laser power measurement up to 300 mW.
Measure in the NIR range with a germanium absorber
Photodiode-based detector for very low power measurement that offers a fast response for the NIR wavelengths (800-1650 nm).
Wide dynamic range
Very low noise
Fast response
Not sensitive to visible light
Optional INTEGRA (USB or RS-232) output
When you choose the INTEGRA output option you get an all-in-one measurement instrument that combines both the detector and the meter in one convenient product. Plug the detector in your PC, install our free software and start measuring.
The most cost-efficient solution
Same measurement performance as our other solutions
No compromise on interface functions and features
Compact solution for OEM applications and field servicing
Save money on recalibration with an all-in-one instrument
