Programmable IR detection module based on HgCdTe TE cooled optically immersed photovoltaic multi-junction detector

LabM-I-10.6

LabM-I-10.6 is a programmable IR detection module with optically immersed photovoltaic detector based on HgCdTe heterostructure, integrated with transimpedance preamplifier. 3° wedged zinc selenide anti-reflection coated window prevents unwanted interference effects. For proper operation programmable „smart” VIGO thermoelctric cooler controller PTCC-01 (sold separately) and Smart Manager Software (freeware) are required. LabM-I-10.6 module comes complete with PTCC-01 and Smart Manager Software is the best solution for prototyping and R&D stage in a variety of LWIR applications. This set provides flexible approach to different needs of system designers.
