Non-cooled type and 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.
