Micro-optical freeform elements for beam-shaping

Hans Peter Herzig, Daniel Infante Gómez

Thin optical beam-shaping elements that are able to produce good quality images and that are operational with different light sources are studied in this work. The influence of the design approach on the smoothness of their surface and on the image quality ...
