ASTROHN Technology Ltd is to launch production of Domestic micro-refrigerators for cooled thermal imagers

ASTROHN Technology Ltd is completing the production equipment for launching the production of integrated microcryogenic Stirling systems. In 2019, ASTROHN Technology Ltd plans to release the first batch of refrigerators for domestic industry.

An important direction in import substitution is the development and production of domestic components for optoelectronic surveillance systems.

New cooling systems will be produced with improved energy performance, and will also be completely interchangeable, i.e. it will be possible to replace the imported MCS with a domestic one without costly redesign: the necessary geometry of the new products is fully consistent with foreign analogs. New domestic MCS will have higher efficiency, reduced weight and size characteristics, increased up to 20 thousand hours of service life to failure, as well as the ability to recharge ultra-pure gaseous helium in operating mode.

Cooled thermal imagers operate in the infrared wavelength range of 3-8 µm (Mid-wavelength infrared, MWIR). This is the range where bodies heated to several hundred degrees Celsius emit. Automatic-homing devices for air defense systems and technical thermal imagers operate in this range. Features of cooled thermal imagers include increased contrast sensitivity, increased detection range up to 20 km. At the same time, the thermal imager itself is an integrated optoelectronic system consisting of an IR lens, a cooled matrix and its cooling system – the microcryogenic Stirling system (MCS).

The launch of the MCS production line is the first and very important step of the engineers of ASTROHN Technology Ltd to create a domestic cooled thermal imager.

Cooled thermal imagers have proven themselves in the service of builders, physicians, power engineers, hunters, and military.
