Fabrication and properties of refractive micro-optical profiles for lenses, lens arrays and beam shaping elements

摘要

An interesting scope in micro optics is the transformation of an arbitrary incoming wave front into another arbitrary intensity distribution. This task includes simple focussing as well as the sophisticated control of the propagation properties of the illumination wave. For the reasons of wave length independence and high efficiency, it is necessary to use refractive elements. The design of these beam shaping elements is made by well-known numerical methods based on wave optics.
