摘要： A lamp has a deformed lamp reflector and a lamp front glass. The deformed lamp reflector is formed by deforming a paraboloid of revolution of a conventional lamp reflector to an aspherical reflection surface which is rotationally symmetrical with respect to an optical axis. The lamp front glass is obtained by deforming the incident plane of a conventional lamp front glass to an aspherical lens surface rotationally symmetric with respect to the optical axis. A light flux radiated from the center point of the light source of an illuminant is reflected by the deformed lamp reflector, and is output through the lens as a parallel light flux having a circular cross section equal in area to the lens.

摘要： An optical system that controls laser beam spot profile for forming a high performance thin film by a laser heat treatment process is provided. In the optical system that irradiates a rectangular laser beam on a film formed on a substrate, intensity distribution forming, apparatus makes the intensity distribution uniform in the longitudinal direction while maintaining the properties of the laser beam 2 such as directivity in the direction of shorter side, making it possible to concentrate the light to a limit permitted by the nature of the laser beam and achieve the maximum intensity gradient on the film disposed on the substrate. Thus a steep temperature distribution can be generated on the film disposed on the substrate and, as a result, high performance thin film can be formed.

A microwave having an electric field component in the direction of thickness of the dielectric member is introduced into the dielectric member through the coupling at an end surface of the dielectric member so that a microwave electric field is formed in the discharge space, and so that the plasma emission medium emits light by electric discharge. The light thus emitted is extracted through the transparent microwave reflecting member.
