HgCdTe (MCT) Detection Module

UM-I-6

3.0 – 6.7 µm, DC – 1 MHz, with optically immersed photovoltaic detector

UM-I-6 is universal „all-in-one” IR detection module. Thermoelectrically cooled, optically immersed photovoltaic detector, based on HgCdTe heterostructure, is integrated with transimpedance, DC coupled preamplifier, a fan and a thermoelectric cooler controller in a compact housing. 3° wedged zinc selenide anti-reflection coated window prevents unwanted interference effects. UM-I-6 detection module is very convenient and user‑friendly device, thus can be easily used in a variety of MWIR applications.
