High Resolution MWIR Thermal Imager
• Type
• Detector type : InSb
• Wavelength : 3~5 µm
• Development
NCSIST has been engaged in the development and production of infrared (IR) detectors for more
than 2 decades. In the early stage, single element InSb detector packaged in glass Dewar and
integrated with Joule-Thomson cooler was used in TC1 missile seeker. In 2000, 2D PtSi focal plane
array (FPA) detector packaged in metal Dewar and integrated with Stirling cooler was put in mass
production and used for portable thermal imager for coast guard. Later, hundreds of 320x256 InSb
FPA combined with integrated Dewar detector cooler assembly (IDDCA) were used in thermal target
acquisition systems equipped on ground battle vehicles. The newest portable thermal imager
using 640x512 InSb detector has been in pilot production now.
• Description
The high resolution mid-wavelength infrared (MWIR) thermal imager incorporates an IDDCA, a video
processing (VP) board and optical lenses which is specially designed for night surveillance,
long-range surveillance, non-destructive testing, industrial processes monitoring and thermal
radiation tracking..
• Specifications

• Status
The 320x256 InSb detector meets all requirements of Taiwan army with the production rate of
several hundred sets per year. The prototype of 640x512 InSb detector has been developed
successfully in 2014. The pilot production of the 640x512 InSb detector is in process and will be
in service with the Taiwan army soon.
