Claim:
1. A lighting apparatus, comprising: a light source that emits light; an optical device that receives light from the light source and outputs light that is more uniformly intense over a predetermined ray angle distribution than light input thereto, the optical device being in a light path of the light source; a multi-reflection device that receives light from the optical device, reflects light multiple times, and emits multiple-reflected light, the multi-reflection device having a light incident surface that receives light from the optical device and a light emission surface that emits multiple-reflected light, the multi-reflection device being in a light path of the light source; a light diffusion device that receives light emitted from the light emission surface of the multi-reflection device and diffuses light, the light diffusion device being in a light path of the light source; and a light focusing optical system that receives light from the light diffusion device and focuses light onto an object to be illuminated, wherein the optical device, the multi-reflection device, and the light diffusion device are axially aligned with an objective lens of the light focusing optical system.
