Explanation of the VIGO Infrared Detector Programme
According to the Materials used, the detectors are divided into two groups
- HgCdTe detectors (often referred to in German as MCT detectors)
- InAs and InAsSb detectors
According to the classification of the semiconductor elements in the periodic table, one also speaks of detectors made of II-VI semiconductors (Hg, Cd, Te) and III-V semiconductors (In, As, Sb).
According to the functional principle, IR detectors are basically divided into three groups
- PV – Photovoltaic
- PEM – Photoelectromagnetic
- PC – Photo resistor (PC = photo conductor)
The infrared detectors are divided into two groups with regard to the type of cooling, the uncooled detectors and the detectors with a 2, 3 or 4-stage TE cooling (corresponding to the coding “2TE”, “3TE” or “4TE” in the detector designation).
In addition, the letters “M” and “I” are used in the detector designations.
- M for multiple junction : A large number of serial p-n junctions increases the sensitivity of the detectors and enables larger detector areas for long-wave detectors in particular.
- I for optical immersion : Optical immersion reduces the electrical area in relation to the optical area, thus significantly improving the noise behaviour of the detector.
Window selection
Uncooled detectors are delivered without a window as standard.
However, it is recommended to install a window in rough, dusty environments.
TE cooled detectors absolutely need a window to protect the detector from ice formation.
All windows have a 3° wedge to suppress interference.
ZnSe is AR coated, for sapphire it is an option. BaF2 windows remain without AR.
