Abstract

Abstract An illuminating apparatus includes a light source section; an integrator section for spreading out and making uniform light generated from the light source; and a collimator lens for making the light which is spread out and made uniform by the integrator section a parallel light flux, wherein the integrator section is formed of a reflecting member for reflecting light generated from the light source section toward the collimator lens. A photo-excited process apparatus includes a pressure reduceable vacuum chamber; an exhaust device connected to the vacuum chamber; a gas supplying device for supplying gas used in a photo-excited process into the vacuum chamber; and an illuminating device for applying light to the gas, wherein the illuminating device includes a light source section, an integrator section for spreading out and making uniform light generated from the light source section, and a collimator lens for making light which is spread out and made uniform a parallel light flux, and the integrator section is formed of a reflecting member for reflecting the light generated from the light source section toward the collimator lens.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 69 words
An illuminating apparatus, comprising: a light source section; an integrator section for spreading out and making uniform light generated from the light source; and a collimator lens for making the light which is spread out and made uniform by the integrator section a parallel light flux, wherein the integrator section is formed of a reflecting member for reflecting light generated from the light source section toward the collimator lens.
Claim 2
Dependent Claim 69 words
An illuminating apparatus, comprising: a light source section; an integrator section for spreading out and making uniform light generated from the light source; and a collimator lens for making the light which is spread out and made uniform by the integrator section a parallel light flux, wherein the integrator section is formed of a reflecting member for reflecting light generated from the light source section toward the collimator lens.
Claim 3
Dependent Claim 51 words
An illuminating apparatus according to claim 1, wherein the integrator section comprises a plurality of elements each having a reflection surface which has a spreading function, and wherein each of the elements is arranged in such a manner that the reflection surfaces of respective elements are arrayed in a periodic manner.
