ABSTRACT:
An optical illumination system includes a radiation source, a condensor, a first lens array including a plurality of first lenses, and a second lens array including a plurality of second lenses. The first lens array converges partial luminous fluxes, the number of which is the same as the number of first lenses, onto the second lenses paired with the first lenses. The second lens array transmits each of the partial luminous fluxes to an object region to be illuminated in such a manner that the partial luminous fluxes are superimposed on each other at the object region. Configurations of the apertures of the second lenses are different from each other and the second lenses are arranged in close contact with each other with the effective region of the second lens array approximating the smallest possible circle.
