ASTROHN Technology Ltd develops the first Russian dual-spectral microbolometric receiveradmin
In 2016, ASTROHN Technology Ltd launched the production of domestic uncooled vanadium oxide microbolometric detectors with the spectral range from 7 to 14 μm.
This range is typical for objects having temperatures close to the temperature of the human body. There are tasks that require the use of a thermal imaging spectrum of 3-5 μm — registering a flare of a rocket, detecting flying objects from a red-hot exhaust gas, etc. This range is characteristic of cooled thermal imagers. The creation of a single-crystal receiver sensitive in two spectral regions (3-5 μm and 7-14 μm) is essential for the development of promising lightweight small-sized devices. The specialists of ASTROHN Technology Ltd managed to solve this problem.
In 2018, the development of a 640×480 pixel two-spectral matrix microbolometric detector sensitive in two ranges of 3-5 μm and 7-14 μm, was completed. The use of receivers in the range of 3-5 µm allows the replacement of expensive cooled thermal imagers with cheap and reliable uncooled ones. Serial production of dual-spectrum modules started in 2019.
On the basis of the dual-band receiver, ASTROHN Technology Ltd has developed a thermal imaging module and a line of lenses for use in promising optical-electronic devices.
