Paper Abstract

We report on an axially asymmetric beam shaping optical system including a diffraction grating. This optical system compensates the astigmatism introduced by change in wavelength of a light source or change in ambient temperature. The phase function of the diffraction grating is determined to minimize the astigmatism by equalizing variation in distance from a light source to an image point on xz plane and variation in that distance on yz plane. This beam shaping optical system relates to a laser printer having an axially asymmetric profile.
