HgCdTe (MCT) Detection ModuleUHSM-I-10.6
3.0 – 12.0 µm, over 700 MHz, with optically immersed photovoltaic detector
UHSM-I-10.6 is ultra high speed „all-on-one” IR detection module. Thermoelectrically cooled, optically immersed 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 I 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.
