Abstract:
1. A spectrometer comprising: an optical body made of a material that permits passage of an object light, to be an object of light separation, of wavelengths within a specified range, with a light separation path for the object light to propagate set therein; a dispersing element provided in a specified position to be on the light separation path; a light entry means located on the entry side of the light separation path to permit the object light to enter; a light detection means located on the exit side of the light separation path to detect the object light entering through the light entry means and spectrally separated with the dispersing element; and an optical connection member for optically interconnecting the optical body and the light detection means, wherein the optical connection member is formed so that a light entry surface for the object light separated with the dispersing element is in contact with a specified surface of the optical body, a light exit surface on the opposite side of the light entry surface is in contact with the light detection means, and the light exit surface is tilted by a specified angle relative to the light entry surface.
