ABSTRACT:
A Schwarzschild optical system comprising a concave mirror having an opening formed at the center thereof and a convex mirror arranged in opposite to the opening of the concave mirror, and has a numerical aperture of at least 0.25 on the object side, the concave mirror being formed to have an aspherical surface. This Schwarzschild optical system has a relatively large numerical aperture, a relatively large departure between the centers of curvature of the concave mirror and the convex mirror, and favorably corrected aberrations.
