METHOD OF DESIGNING PROJECTION LENSES WITH PUPIL ABERRATION

A method to design projection lenses or zoom lenses with distorted or uncorrected pupil aberration (mostly Spherical Aberration or spherochromatism). By introducing some pupil aberration, the designer has a new variable to correct for field and aperture aberrations. The result is a design that requi...

Summary:A method to design projection lenses or zoom lenses with distorted or uncorrected pupil aberration (mostly Spherical Aberration or spherochromatism). By introducing some pupil aberration, the designer has a new variable to correct for field and aperture aberrations. The result is a design that requires fewer lens count for the same performance parameters than more complex projection lenses, and is more compact. Lenses designed by the method are illustrated.
