Abstract

An optical system comprising: an anamorphic optical subsystem that includes: an entrance plane, an exit plane, and at least one optical element, in an optical path from said entrance plane to said exit plane, that effects an aspect ratio distortion, by a factor r>1, on light that has a wavelength in a predetermined wavelength interval and that enters said anamorphic optical subsystem via said entrance plane from an infinitely distant point source at any azimuth and at any elevation of up to at least about five degrees from an optical axis of said anamorphic optical subsystem, such that energy of said light within an Airy disk of said light as said light exits said anamorphic optical subsystem via said exit plane, is at least about f(r) of a diffraction limit value of said energy, wherein f(x) is a monotonic function of x such that f(1)=1, f(1)≥- 0.737, f(2)≥0.6 and f(∞)=0.
