Apparatus for homogenizing light beam emerging from at least one light source, comprises optical system with prism whose boundary surfaces reflect light beams falling onto them at shallow angles

摘要

The apparatus for homogenizing a light beam emerging from at least one light source and traveling along an axis which extends from a light entry to light exit area, and is angularly displaced at least at one point, comprises an optical system at that point with at least one reflecting area (38) and a prism (36) whose boundary surfaces reflect light beams falling onto them at shallow angles.
