ABSTRACT:
In a Schwarzschild optical system comprising a concave mirror having an aperture at its center and a convex mirror disposed in face of the concave mirror, the convex mirror is coated with a multilayer film such that an incident angle .theta.02 on the convex mirror at which reflectance is maximized with respect to light of a particular wavelength satisfies the following condition:
By such structure, the Schwarzshild optical system of the present invention provides an important advantage in practical use that transmittance efficiency is extremely favorable.
