InGaAs Detector

A hermetically sealed InGaAs detector for measuring LEDs, laser diodes, and IR optical radiation is more sensitive and stable than a thermal detector, according to the company. The IL SED (SEL) 007 detector is a very stable quantum device with a flat spectral response that operates at room temperature without cooling or the need for a chopper. Featuring >0.9 Amps/Watt sensitivity, low dark current, low noise, and >1 Gigohm shunt resistance, the 3 mm diameter detector rejects long wave sources of heat that can compromise accuracy in the near infrared region, while rejecting the visible.

Suitable for making absolute measurements and for low level spectral studies where weak signals are typical, the detector operates from 850 to 1650 nm at room temperature. Optional input optics include a diffuser for measuring power density, a narrow beam adapter for direct power measurements, a flexible fiber optic light guide for remote access, and various filters for bandpass alteration.
