Abstract
An ellipsoid mirror with Φ500 mm aperture has been successfully manufactured by NAIRC. The parameters of the mirror are as follows: diameter is Φ500 mm, radius of curvature is 1996 mm, conic constant k=-0.9545, requirements of surface accuracy are λ/10 (P-V) and λ/40 (RMS), (λ=632.8 nm). Based on the surface type, three kinds of test optics are designed. The errors of the elements in the testing optical path are analyzed. The small tools are used to figure the asphericity of the mirror. Finally surface accuracy of λ/10 (P-V) and λ/50 (RMS) are reached.
