HgCdTe (MCT) Detection Module

UM-10.6

2.0 – 12.0 µm, DC – 70 MHz, with photovoltaic multiple junction detector

UM-10.6 is an universal „all-in-one” IR detection module. Thermoelectrically cooled 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-10.6 detection module is very convenient and user‑friendly device, thus can be easily used in a variety of LWIR applications.
