| Abstract: | It's very difficult for manufacture and test of an off-axis convex hyperboloidal surface in the area of manufacture and test of aspherical optical surfaces.With the diameter of an off-axis convex hyperboloidal mirror is 230mm and off-axis magnitude is 226mm,a new method in which the off-axis convex hyperboloidal mirror is manufactured singly and tested with a deflection angle using an off-axis Hindle ball is proposed.Besides,unit manufacture technology is given and problems in building test configuration ar... |
