METHOD FOR MAKING MIRROR AND MIRROR MADE USING THIS METHOD Russian patent published in 2023 - IPC G02B5/08 

FIELD: optical instrument making.

SUBSTANCE: invention can be used in the field of optics, laser technology and optoelectronics. When implementing a method for manufacturing a mirror, which includes manufacturing a mirror body from an aluminium-silicon alloy, coating is applied to the working surface of the body, optical processing of the coating is carried out, and reflective and protective layers are applied to the coating. The mirror body is made of an aluminium-silicon alloy with a silicon content of 30-40% by weight, and the coating is formed by fusing a plate of TF 1608-B2 glass with a thickness of 1.5-2.5 mm at a temperature of 480-520°C for 30-40 minutes and cooling at a rate of no more than 150°C/hour, subsequent mechanical processing to a coating thickness of 0.9 - 1.1 mm and three-time cyclic heat treatment of the coated mirror body at temperatures minus (80±5)°C - plus (100±5)°C with isothermal exposures for 20-30 minutes, and then the optical processing of the coating and application of reflective and protective layers are carried out.

EFFECT: simplification of the method of manufacturing a mirror.
