Abstract

The design principles of three familiar compensators are introduced. They are null lens compensator, offner compensator and reflective mirror compensator. Base on the three different theories, three different kinds of compensators for the testing of F/3 hyperbolic mirror are designed. The initial parameters of every compensator are analyzed in detail. The residual wavefront error, RMS radius of the spot diagrams and the tolerance of the three compensators are presented respectively. Due to the residual wavefront error consisted in these compensators themselves, higher order aspheric terms will be introduced into the hyperbolic mirror when using these compensators to test the mirror during the process of the fabrication. These higher order aspheric terms will influence the image quality of R-C system which primary mirror is this hyperbolic mirror. The simulation of this influence is analyzed in this paper. The residual wavefront error of the three final designs are all less than λ/30. The RMS radii of the spot diagrams are all less than 0.48μm.
