Abstract
An illumination system includes a light source device including a light source and a reflection mirror for reflecting light from the light source, and an optical system, including a plurality of lenses, for illuminating a surface with light from the light source device. A shadow of the light source is projected from the light source device in a direction inclined with respect to an optical axis of the optical system such that the shadow of the light source is not substantially projected on the surface through the optical system.
