Abstract: A spectroscopic module includes M beam splitters that are arranged along an X direction, where M is a natural number of 2 or more; M bandpass filters disposed on one side in a Z direction with respect to the M beam splitters, each of the M bandpass filters facing each of the M beam splitters; a light detector disposed on the one side in the Z direction with respect to the M bandpass filters and includes M light receiving regions, each of the M light receiving regions facing each of the M bandpass filters; a first support body supporting the M beam splitters; and a second support body supporting the M bandpass filters. Each of N beam splitters among the M beam splitters has a plate shape and has a thickness of 1 mm or less, where N is a natural number of 2 to M.

Abstract: In a spectroscopic module, a light shielding member is disposed between a plurality of bandpass filters and a light detector. The light shielding member includes a plurality of wall portions. The plurality of wall portions are arranged along an X direction with a light passage opening interposed therebetween, each of a plurality of optical paths from the plurality of bandpass filters to a plurality of light receiving regions passing through the light passage opening. A first wall portion and a second wall portion adjacent to each other among the plurality of wall portions are in contact with the bandpass filter, the bandpass filter corresponding to the light passage opening between the first wall portion and the second wall portion. A width in a Y direction of the light passage opening is larger than a width in the Y direction of the bandpass filter.
