Features

/K6C 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. /K6C Photoconductive element that decreases its resistance by input of infrared light /K6C Custom devices available Custom devices not listed in this catalog are also available with different spectral response, active area size and number of element. /K6C Easy-to-use infrared detector modules with preamp available
