The utility model provides a large -scale convex -concave mirror combined machining machine tools. The main problem of solving current convex -concave mirror machine tool function singleness. Its characterized in that: vertical lathe bed (1) down has the workstation, and the workstation is ...
To solve the problem, we need to determine the radius of curvature of the curved surface of a plano-convex lens that behaves like a concave mirror when its plane surface is silvered. The given radius of curvature of the concave mirror is 20 cm, and the refractive index of the lens materi...
