Gentec-EO PE5B-Ge-D0 Photodiode Detector Description:

Datasheet(CN) Datasheet(EN) PC-Gentec-EO User's Manual QE User's Manual INTEGRA User's Manual

Gentec-EO PE5B-Ge-D0 Photodiode Detector for laser energy measurement up to 2.4 nJ.

Measure in the NIR range with a germanium absorber

Germanium photodiode-based energy detector for very low energy measurement that offers a fast response for the NIR wavelengths (800-1650 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.

3 sensors available

PE-B-SI family: 3 and 10 mm Ø silicon sensors for 0.21 to 1.08 µm

PE5B-GE: 5 mm Ø, germanium sensor for 0.8 to 1.65 µm

PE3B-IN: 3 mm Ø, InGaAs sensor for 0.9 to 1.7 µm

Smart interface

Containing all the calibration data
