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.
