Gentec-EO PE3B-In-D0 Photodiode Detector for laser energy measurement up to 245 pJ.
InGaAs absorber
Our InGaAs absorber makes it possible for this photodiode-based detector to measure very low energy levels fast in the NIR wavelength range (900 – 1700 nm).
Wide dynamic range
Very low noise
Not sensitive to visible light
Less sensitive to vibrations than pyroelectric detectors
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
Key Features
Very low noise level
Take measurements with a noise level as low as 8 fJ (model PE3B-Si only) with the M-LINK, MAESTRO and S-LINK monitors.
