Abstract

PURPOSE:To provide a reflection reference plate which has excellent reproducibility by forming a reflecting film on one side surface of an optical material by vacuum deposition or silver mirror reaction or the like. CONSTITUTION:A reflecting film 4 is formed integrally with an optical material 3 made of transparent glass plate or the like on one side surface of the material 3 by means of vacuum deposition or silver mirror reaction or the like. Thus, it can eliminate unnecessary spectral characteristics to thereby enhance its reproducibility. When fine ruggedness is formed on the reflecting surface of the material 3 as a diffusing surface 31 and the film 4 is formed thereon, it can eliminate the directivity of the reflecting lights to thereby omit the precise optical axis alignment procedure. Further, when the flatness of the diffusing surface 31 is altered, it can obtain a reference plate having arbitrary reflecting amount.
