Abstract

PURPOSE:To obtain a reflecting mirror which is free from nonuniform molding strain and thermal deformation, is reduced in weight and has high accuracy by using a ceramic (CFRP) sheet which has uniform quality, isotropic mechanical and thermal characteristics, coefft. of thermal expansion smaller than the coefft. of thermal expansion of a high-polymer foam and a low density as a core material after working said sheet to a currugated fiberboard shape. CONSTITUTION:The fiber reinforced plastic (FRP) sheets 2 are adhered to both faces of the core material 8 by an adhesive agent 3. A reflection film 4 is formed by vapor deposition, etc., on the surface to be formed as the reflection surface of the FRP sheet 2. Rays of an IR to UV region are reflected by the reflecting mirror constituted in the above-mentioned manner. The core material 8 consists of a currugated sheet 9 formed by folding the ceramic sheet having 0.03-1.0g/cm<3> density and uniform quality to the corrugated shape and the flat ceramic sheet 10 adhered thereto. Since this reflecting mirror consists of the core material 8 having the isotropic mechanical and thermal characteristics, the generation of the nonuniform molding strain and thermal deformation is obviated. The core material 8 can be made to have about <=1X10<-5> deg.C coefft. of thermal expansion, by which the reflecting mirror having the excellent thermal dimensional stability, lightweightness, high rigidity and high accuracy is obtd.

Since the structure is similar to that of a conventional PRP counter-reflector, if the core material (1) is a non-nicum core, the mechanical and thermal properties in one plane are not isotropic, so for example, saddle-shaped molding distortion may occur. or thermal deformation may occur. Even if the Nicum core is divided and arranged with directionality in mind, anisotropy remains within the two divided cores, and uneven molding strain and thermal deformation cannot be completely eliminated. Furthermore, when the core is divided, the mirror surface is deformed due to the discontinuity of the core divided portion. As a result, when a light beam is reflected to form an image, the image becomes blurred, and even when the light beam emitted from the light source at the focal point of the two reflecting mirrors is reflected, it does not become a parallel light beam with a uniform intensity distribution.
