Paper Abstract

This paper presents different testing methods of convex secondary mirrors including stages of grinding and polishing of epy optical parts. Testing method by spherometer in longitudinal and linear directions, testing methods by overlapping of wavefronts in horizontal and vertical layouts are described. Practicable testing schematic of a convex hyperboloid with diameter up to 4m is also presented.
