Remarks to the Infrared Detectors Program
In relation to the functional principle the detectors can be divided into three groups
In relation to the cooling the detectors are divided into two groups, the room temperature detectors and the detectors with a 2, 3 or 4 stage thermoelectric cooling (named with 2TE, 3TE or 4TE)
In addition the letters „M“ and „I“ are used in the detector types.
M for Multiple Junction: A multiple of serial p-n-transitions increases the responsivity of the detectors and make it possible to produce long wave length detectors with larger areas.
I for optical Immersion: The principle of optical immersion decreases the electric area in relation to the optical area with resulting improved noise parameter of the detector
