A light guide for illumination, characterized in that it has a second spectroscopic section provided on the other side of the light guide path section facing the first spectroscopic section and guides the light to a corresponding illumination section. (2) A claim characterized in that the second spectroscopic section is a reflective surface formed such that the farther it is from the light entrance section, the smaller the angle it makes with the extension direction of the illumination section.
The light guide for illumination described in (1). (3) The first spectrometer specifies the light toward one side in the extending direction of the corresponding illumination section, and the second spectrometer specifies the light toward the one side of the corresponding illumination section. 2. The light guide for illumination according to claim 1, wherein the light guide is formed so as to disperse light toward the other side.
