Abstract
An optical system for illuminating a sample with a line beam includes a light source, a beam shaper for transforming the beam of light emitted by the light source into an intermediate astigmatic image, and an imaging system for transforming the intermediate astigmatic image into a final astigmatic image and for illuminating the sample. The beam shaper provides different non-unity magnifications in a lateral plane and in a transversal plane, and comprises a toroidal entrance surface for implementing the angular magnification and angular reduction and a toroidal exit surface with finite radii of curvature.
