ABSTRACT:
A parallel light generating apparatus uses two arrayed mirrors. The apparatus includes a parabolic mirror, a lamp located at the focal point of the parabolic mirror, and first and second arrayed mirrors disposed in parallel, each of which is divided into plural portions, with each portion being divided again into parts. A panel is situated between the arrayed mirrors and has a plurality of holes corresponding to each portion of both mirrors, for blocking non-parallel light.
