MIRROR AND METHOD OF MAKING SAID MIRROR Russian patent published in 2010 - IPC G02B5/08 

FIELD: physics.

SUBSTANCE: mirror consists of a substrate and separation and reflecting layers. The substrate is made from composite material containing the following, vol. %: diamond 50-75, silicon carbide 20-45, silicon 3-20. The separation layer contains the following, vol. %: silicon carbide 10-35 and silicon 65-90. The method involves making a substrate, moulding a separation layer on its surface and optical processing of the surface and depositing a reflecting layer, wherein the separation layer is obtained by impregnating a porous carbon-fibre workpiece placed on the surface of the substrate with liquid silicon.

EFFECT: improved operational characteristics, simple technology of making the mirror.
