MCT photoconductive detectors

P3257/P3981/P2750 series

Non-cooled type and TE-cooled type suitable

for long, continuous operation

Features

Applications

Choice of spectral response (up to 12 μm)

Radiation thermometer

Gas analyzer

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.

Infrared spectrophotometers

FTIR

Photoconductive element that decreases its resistance

by input of infrared light

CO2 laser monitor

Custom devices available

Custom devices not listed in this datasheet are also available

with different spectral response, photosensitive area size

and number of element.

Options (sold separately)

Easy-to-use infrared detector modules with preamp available
