Abstract
An optical element of this invention converts incident light having a predetermined shape and a predetermined intensity distribution into output light having a desired shape and a uniform intensity distribution. Furthermore, in an optical device of this invention, which has this optical element as a first optical element, a light source radiates a light beam having the predetermined beam shape and the predetermined intensity distribution, the first optical element shapes the beam shape of the incident light beam into one of rectangular, circular, and elliptic shapes having a uniform intensity distribution, and a second optical element gives a collimation to the incident shaped light beam.
