HgCdTe (MCT) Detection Module

HgCdTe (MCT) Detection Module

UHSM-10.6 is ultra high speed „all-in-one” IR detection module. Thermoelectrically cooled, photovoltaic detector, based on HgCdTe heterostructure, is integrated with transimpedance, AC coupled preamplifier, a fan and a thermoelectric cooler controller in a compact housing. 3° wedged zinc selenide anti-reflection coated (wZnSeAR) window prevents unwanted interference effects. UHSM-10.6 detection module is very convenient and user‑friendly device, thus can be easily used in a variety of LWIR applications requiring wide frequency bandwidth.
