Beam-shaping lenses in illumination optics

摘要

Beam-shaping optics are used in various optical fields to change the luminous intensity distribution. In this paper a flexible method is presented to design beam-shaping optics with aspherical surfaces transforming the intensity profile of the light beam into any desired profile. The method is applied to a collimator lens that transforms a beam from a Lambertian emitter to a uniform light distribution.
