ABSTRACT:
Different species of catoptric lens arrangements are shown, each one of the disclosed species being characterized by use of a quadratic conic mirror having real or virtual focal points displaced from a lens axis. With a quadratic conic mirror having such a characteristic, the image points of axial, or paraxial, rays are similarly displaced so that aperture blockage may be eliminated and achromatic aberrations may be reduced to such an extent as to make the lens arrangement diffraction limited.
