Abstract

A mirror support for an optical mirror and a method for producing an optical mirror are disclosed. In an embodiment a mirror support includes a mirror body comprising a diamond particle reinforced aluminum composite material and a polishing layer arranged on the mirror body, wherein a content of diamond particles in the aluminum composite material is between 5% by mass and 50% by mass inclusive and is selected such that a thermal coefficient of linear expansion of the mirror body is adapted to a thermal coefficient of linear expansion of the polishing layer.
