T2SL Cooled FPA Thermal Imaging Detector

1. Introduction to Type II Superlattice Cooled Infrared Detector

Type II superlattice is an infrared optoelectronic material. Superlattice, also known as coupled multiple quantum wells, is a multilayer film material formed by alternating thin layers of two different components in the form of nanometers. The barrier layer is thin and the coupling between adjacent wells is strong.
 
As one of the most cutting-edge technologies in the infrared thermal imaging industry, type II superlattice has unique advantages in the production of long-wave, duel-color, large area array cooled infrared focal plane detectors, and high-temperature devices.
 

2. Advantages of T2SLCooled Infrared Detector
 
Type II superlattice is mainly used in the fabrication of high-performance infrared focal plane imaging arrays. Based on Type II superlattice materials, the cooled infrared focal plane detector products have many advantages, which have broad market prospects in various fields.
-High quantum efficiency, high frame rate, high sensitivity,
-Strong penetration, strong anti-interference
-All-weather work
-Wider response band and higher operating temperature
-Small dark current, high detection efficiency of long wave/dual color
-High detection rate, better uniformity, more suitable for large area array devices
 
 3. Application of LWIR, MWIR/LWIR Duel-color Cooled Infrared Detector
 
In infrared thermal imaging technology, long-wave thermal detectors has strong penetration through dusty atmospheres, are not disturbed by sun glint effects and light reflections. Outstanding image quality can be obtained in various complex environments, such as vehicle drives in the dusty atmosphere, ship sails on the water with reflective light and aircraft is flying through the cloud.
 
The dual-color cooled infrared detector combines the advantages of mid-wave and long-wave detection into one cooled infrared detector assembly, which can simultaneously perform high-performance imaging in the duel wavebands, greatly reducing the false alarm rate. It can be used for the detection of complex backgrounds and the monitoring of high-speed moving targets.
