LabM-I-4

2.4 – 4.3 µm and over 5 MHz HgCdTe programmable, laboratory IR detection

module with optically immersed photovoltaic detector

LabM-I-4 is a laboratory IR detection module with optically immersed photovoltaic detector based on HgCdTe heterostructure,

integrated with transimpedance, programmable preamplifier. 3° wedged sapphire 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-4 module comes complete with PTCC-01 and Smart Manager is the best solution for prototyping and

R&D stage in a variety of MWIR applications. This set provides flexible approach to different needs of system designers.
