ABSTRACT:
A holding device for holding an optical element to be ground is arranged such that pressure applied to a receiving face of the optical element on the holder base is made different in the radial direction in order to eliminate deformation, positional deviation or inclination of the optical element due to grinding resistances during grinding or due to high-pressure grinding. An elastic member is employed as an elastic member, or a receiving member capable of absorbing the positional deviation, the inclination, or the like of the optical element during grinding thereof is used.
