Abstract

PURPOSE: To efficiently produce a round spot light by making the beam from a semiconductor laser parallel with the use of an optical system, which has different focal lengthes for the longitudinal and transverse directions, so that the crosssection of the light flux may be used in an anamorphic afocal optical system.
