METHOD OF MAKING LIGHT OPTICAL MIRRORS Russian patent published in 2016 - IPC G02B5/08 C03C27/00 

FIELD: optics.

SUBSTANCE: invention relates to production of mirror-lens systems and can be used in optical and optoelectronic industry, including in production of mirrors of optical telescopes. Disclosed is method of making light optical mirrors based on silicon carbide ceramic SiSiC and working layer of optical borosilicate glass, in which plate made of silicon carbide ceramic is subjected to annealing in air at 900-1,000 °C for 1.5-2 hours, then polished and connected with plate made from borosilicate glass by soldering at temperature 800-850 °C in protective atmosphere for 0.5-1 hours. Obtained workpieces are ground, polished and mirror reflecting layer is applied using known technology.

EFFECT: technical result of disclosed method enables to obtain optical mirror with strong pores-free attachment of layers and good resistance to external effects: temperature cycling in range from minus 30 to plus 50 °C and gas medium pressure of 10^-3 Pa.
