Great success of large diameter

Great success of large diameter

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 [...]

Single-crystal germanium production launched in Lytkarino

Single-crystal germanium production launched in Lytkarino

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 [...]
