P3257_15 Datasheet, PDF (1/7 Pages) Hamamatsu Corporation – MCT photoconductive detectors

MCT photoconductive detectors
P3257/P3981/P2750 series
Non-cooled type and TE-cooled type suitable
for long, continuous operation
Features
Choice of spectral response (up to 12 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
Custom devices available
Custom devices not listed in this datasheet are also available
with different spectral response, photosensitive area size
and number of element.
Easy-to-use infrared detector modules with preamp available
Applications
Radiation thermometer
Gas analyzer
Infrared spectrophotometers
FTIR
CO2 laser monitor
