A thermographic camera (also called an infrared camera or thermal imaging camera or thermal imager) is a device that creates an image using infrared radiation, similar to a common camera that forms an image using visible light. Instead of the 400–700 nanometre range of the visible light camera, infrared cameras are sensitive to wavelengths from about 1,000 nm (1 μm) to about 14,000 nm (14 μm). The art of capturing and analyzing the data they provide is called thermography.
Specialists of ASTROHN Technology ltd. in Mobilization – a special report on Russia-24 TV channel. Vladimir Popov, The general director of ASTROHN Technology ltd. demonstrates growth process of germanium crystals in a special growth unit. This rare metal is used at Lytkarino Optical-Mechanical Design Bureau to produce lenses for thermal imagers. The single crystal is cut into thin plates for the subsequent manufacture of customized lenses of the desired diameter. If you set the glass against germanium, the glass will not [...]
