INFRARED
DETECTOR
MCT photoconductive detector
Dewar type detector with high sensitivity and high-speed response in long wavelength range
P2748/P5274 series, P3257-50
Features
l Choice of spectral response range (up to 25 m)
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 FTIR
l Infrared spectrophotometer
l Thermal imaging
l Remote sensing
l CO2 laser detection
Accessories (Optional)
l Valve operator
A3515
l Amplifiers for dewar type MCT photoconductive detector
C5185
l Infrared detector module with preamp
