WebCollimating light is a common task in optical design. The smaller the source, the simpler the optics required for collimation. Small sources cannot emit sufficient power for some demanding applications. Larger sources are required. The physical limits of collimation due to the conservation of ´etendue and skewness are discussed. WebRecently, the desire to use freeform optics has been increasing. Freeform optics can be used to expand the capabilities of optical systems and reduce the number of optics needed in an assembly. The traits that increase optical performance also present challenges in … WebMay 3, 2016 · The minimum inverse-square distance is determined by the type and size of the light source, lens, reflector, etc., and must be considered individually for each unit.
