Turkey serially produces Quantum-well infrared photodetectors for military application

After 20 years of research and development, Turkish military electronics giant ASELSAN designs and produces QWIP IR sensors locally, very few countries have this capability

(From Wikipedia) A quantum-well infrared photodetector (QWIP), is an en.wikipedia.org/wiki/Infrared en.wikipedia.org/wiki/Photodetector made from en.wikipedia.org/wiki/Semiconductor materials which contain one or more en.wikipedia.org/wiki/Quantum_well. These can be integrated together with electronics andhttp://en.wikipedia.org/wiki/Optics to make en.wikipedia.org/wiki/Infrared_camera for en.wikipedia.org/wiki/Thermography. A very common well material is en.wikipedia.org/wiki/Gallium_arsenide, used with barrier material en.wikipedia.org/wiki/Aluminium_gallium_arsenide. It is considered a game changing technology for such applications as air-to-air missiles, where it can detect objects which are well outside the visual range of the pilot.

There are several companies world-wide manufacturing infrared systems which use QWIPs-Sofradir - French
-AIM - Germany
-SCD - Israel
-Raytheon - USA
-Aselsan - Turkey

Here on the video(It's in Turkish) They explain that every material having greater temperature than -273 Celcius emits Infrared light. Some military applications are shown on FLIRs and missile sensors, and they visit the factory producing QWIP IR sensors. They wear suits and enter cleanroom and take a look at the wafer including sensors.

Progress of QWIP sensors by years


The newly built factory of Aselsan in Gölbaşı, they will also make RADARs for Turkish Ships and Fighter planes, apparently it's the biggest RADAR factory in Europe and ASIA
