Small-size IR detection module based on HgCdTe TE cooled optically immersed phoconductive detector
SM-I-12
SM-I-12 is an ultra-small IR detection module. Thermoelectrically cooled, optically immersed photoconductive detector, based on HgCdTe heterostructure (PCI-3TE-12-1×1-TO8-wZnSeAR-36) is integrated with transimpedance, AC coupled preamplifier. There is a possibility to manually adjust gain of the signal. 3° wedged zinc selenide anti-reflection coated window prevents unwanted interference effects. SM-I-12 is easy to assembly in space limited measuring systems of FTIR applications.
