Abstract

The projector for appearance test of the present invention comprises an illuminating light source, a reflecting optical system reflecting the light from the illuminating light source to an inspected member, and a converging optical system disposed in the reflecting light route of the reflecting optical system, wherein the converging optical system is divided into at least two parts so that the entire surface of the inspected member can be radiated by an illumination light flux from each part of the converging optical system.
