Abstract:
1. A spectrophotometer comprising: an optical waveguide; a light entrance slit provided at an end face on the inner side of the optical waveguide, for bringing an incident light into the optical waveguide; an optical element provided at an end face on the inner side of said optical waveguide or at an interior of said optical waveguide, for separating the incident light brought in the optical waveguide into a spectrum; and a photoelectric conversion device provided at an end face on the inner side of said optical waveguide, for detecting the incident light separated into the spectrum at said optical element; wherein said optical waveguide, said light entrance slit, and said optical element are integrally formed on an optical waveguide board, and a photoelectric conversion device substrate having said photoelectric conversion device formed thereon is mounted on the optical waveguide board.
