Abstract

PURPOSE:To obtain a compact optical system of a light source for a light guide which has high efficiency without uneven quantity of light by providing an averaging optical system consisting of a diffusion face, concave lens and circular cylindrical-faced reflecting mirror. CONSTITUTION:A spot light source 101 is a halogen lamp. A concave mirror 301 and a condenser lens 302 are used as a condensing optical system and an IR cut filter 103 is provided. The diffusion face 303 and the concave lens 304 are installed near the condensing face by the condensing optical system of the source 10 and the circular cylindrical-faced reflecting mirror 305 is installed behind the same by matching the central axis of the cirlcular cylinder and the optical axis. A light guide incident part 105 bundled with optical fibers 106 is disposed. The diffusion plate 303 may diffuse the light weakly to the extent that the image of the filaments by the condensing optical system does not appear sharply. The function to provide inclination to rays is provided by the lens 304 and therefore the efficiency of utilizing the luminous flux is high.
