MCT photoconductive detector

P2748/P5274 series P3257-50

Dewar type detector with high sensitivity and high-speed response in long wavelength range

Features

Applications

Choice of spectral response range (up to 25 µm)

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.

Photoconductive element that decreases its resistance

by input of infrared light

FTIR

Infrared spectrophotometer

Thermal imaging

Remote sensing

CO2 laser detection

Micro-cooled type available

This type of cooling does not require pour-filled liquid

nitrogen.

Custom devices available

Custom devices not listed in this catalog are also available

with different spectral response, active area sizes and

number of elements.

Accessories (Optional)

Valve operator

Amplifiers for dewar type MCT photoconductive detector

C5185

A3515

Glass dewar type not requiring repumping is also provided.
