Document Type and Number:
Japanese Patent JP6809991
Kind Code:
B2
Abstract:
To provide a spectroscope capable of obtaining a large amount of information with high sensitivity and high accuracy.SOLUTION: A spectroscope comprises a first diffraction body having a first diffraction surface and a second diffraction body having a second diffraction surface and a frame body housing the first diffraction body and the second diffraction body so that the first diffraction surface and the second diffraction surface are exposed alongside each other. At least one of opposite surfaces of the first diffraction body and the second diffraction body has a recess. The spectroscope has a ceramic solid sphere protruding more than the recess.SELECTED DRAWING: Figure 5
