home-icon/Products / Infrared Detections Modules / Selected Line / HgCdTe programmable MWIR detection module LabM-I-5

Programmable IR detection module based on HgCdTe thermoelectrically cooled optically immersed photovoltaic detectorLabM-I-5

LabM-I-5 is a detection module featuring a TE-cooled, optically immersed photovoltaic IR detector based on an HgCdTe heterostructure (PVI-2TE-5-1×1-TO8-wAl2O3-36), integrated with a programmable, transimpedance amplifier (PIP series).
For proper operation, the programmable VIGO thermoelectric cooler controller PTCC-01 (sold separately) and Smart Manager Software (freeware) are required.
The LabM-I-5 detection module comes complete with PTCC-01 and Smart Manager Software, making it the best solution for prototyping and the R&D stage in various MWIR applications. This set provides a flexible approach to the different needs of system designers.
