Abstract

PURPOSE:To obtain an arbitrary spectral distribution by a spectroscope without any influence thereupon of an incident angle of incident light, by using a spectroscopic filter consisting of a combination of a diffusion plate and an interference filter 1 of laminated films and a photoelectric detector. CONSTITUTION:A diffusion plate 4 is fixed to the surface of an interference filter 1 of laminated films to form a spectroscopic filter. The diffusion plate 4 is adapted to maintain predetermined diffusion characteristics irrespective of the magnitude of an incident angle. The light diffused perpendicularly from the diffusion plate 4 has the highest intensity. The intensity of diffused light is decreased as an angle at which the light advances outwardly is increased. A spectroscopic filter 14 thus formed is disposed in an opening at an upper end of a casing 13 such that the diffusion plate 4 is on the upper side. A photoelectric detetor 15 is disposed in a bottom portion of the casing 13, and a detecting output of the detector 15 is connected to an amplifier display circuit. As a result, a spectroscope having spectral characteristics with a high transmissivity can be obtained.
