摘要：
An illumination optical system comprises a multi-beam generator which includes a plurality of each of two kinds of lens elements different in optical characteristics and which is interposed between a source for generating a collimated light beam and a light condenser. The multi-beam generator generates a large number of secondary light sources from the collimated light beam. The illumination optical system is capable of supplying illuminating light rays having an extremely uniform illumination distribution.
