INFRARED DETECTOR

MCT photoconductive detector

P3257/P3981/P2750 series

Non-cooled type and TE-cooled type suitable for long, continuous operation

Features

The band gap can be adjusted by controlling the composition

ratio of HgTe and CdTe. Utilizing this fact, various types are

available in different spectral characteristics.

l

Photoconductive element that decreases its resistance

by input of infrared light

l

Custom devices available

Custom devices not listed in this catalog are also

available with different spectral response, active area

size and number of element.

l

Easy-to-use infrared detector modules with preamp

available

Applications

l
