Experts of ASTROHN Technology Ltd. have elaborated the production technology of single crystals germanium with high optical homogeneity (uniform dopant distribution), confirmed by an electrical resistivity four-probe method. The new technology was applied to produce prototypes, which would be used in the design of new generation infrared equipment.
Specialists of ASTROHN Technology ltd. in Military Acceptance – a TV-show on Zvezda TV-channel. It is a marvel that having reprofiled these enterprises continue to fulfill the state defense order, so getting weaker is not about us. We are all get used to the fact that thermal imaging cameras had been previously imported from France or the United States. The heart of the issue is the lenses: the smaller the microbubbles in the glass are, the higher the quality is. The [...]
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 [...]
ASTROHN Technology Ltd specialists have developed a large-diameter infrared (IR) lens. This caused the need to obtain a single crystal of germanium of a sufficiently large diameter (about 200 mm) for the manufacture of an input lens. In addition, the problem of high structural excellence of the workpiece was critical. Therefore, the workpieces must be single-crystal, so that internal defects do not weaken the passage of the beam. Such blanks can only be obtained using the Czochralski method. There is [...]
Since the beginning of April 2017, ASTROHN Technology Ltd launched plants for the production of germanium (Ge) and silicon (Si) single crystals by Czochralski method, and implemented advanced technologies for producing single-crystal germanium with increased uniformity. A full-cycle production was organized, with the in-house waste processing. The company is developing such areas as production of germanium crystals with increased uniformity with a diameter of up to 500 mm. The equipment and technologies of the company make it possible to produce aspherical [...]
