Rectifying mirror
First Claim
1. A mirror for use in a catadioptric system, comprising a substantially circular mirror having a rotationally symmetric cross section by a set of points substantially close to a curve satisfied by a differential equation as follows:
- where x is the horizontal coordinate of the mirror and where the largest value of x is the radius of the mirror and F(x) is the cross-sectional shape.

Abstract
A mirror for use in a catadioptric system, is provided which is a substantially circular mirror having a rotationally symmetric cross section by a set of points substantially close to a curve satisfied by a differential equation as follows:
where x is the radius of the mirror and F(x) is the cross-sectional shape. Alternatively, a mirror for use in a catadioptric system, is provided which is a substantially circular mirror having a rotationally symmetric cross section determined by a differential equation as follows:
where x=f(t)/(F(t)−f−h), f is the focal length, h is the height above an object plane, and F(t) is the cross-sectional shape.
