INFRARED DETECTOR
MCT photoconductive detector
P2748/P5274 series, P3257-50
Dewar type detector with high sensitivity and high-speed response in long wavelength range
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
Micro-cooled type available
This type of cooling does not require pour-filled liquid
nitrogen.
l
Custom devices available
Custom devices not listed in this catalog are also available
with different spectral response, active area sizes and
number of elements.
Glass dewar type not requiring repumping is also provided.
Applications
l
Choice of spectral response range (up to 25 µm)
