MCT photoconductive detectors  
P2748/P5274 series  
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.  
FTIR  
Infrared spectrophotometers  
Thermal imaging  
Remote sensing  
CO2 laser detection  
Photoconductive element that decreases its resistance  
by input of infrared light  
Custom devices available  
Custom devices not listed in this catalog are also available  
with different spectral response, active area sizes and num-  
ber of elements.
