Abstract
PURPOSE: To facilitate the operation of a high-precision oblate spheroid by putting a main mirror into oblate spheroid lens operation by using an oblate spheroid correcting lines in combination.
CONSTITUTION: Oblate spheroid correcting lens 3 is arranged closely to the mirror surface of main mirror 1 forming a light Schmidt tye optical system together with correcting lens 2, so that main mirror 1 will provide oblate spheroid lens operation substantially. Thus, the oblate spheroid of high precision can be formed easily and securely.
