1. An identification apparatus comprising:
a plurality of light collection optical systems configured to collect scattered light from a plurality of test substances;
a spectroscopic element configured to disperse a plurality of light beams from the plurality of light collection optical systems;
an imaging unit including a plurality of light receiving elements arrayed in a row direction and a column direction, and configured to receive a plurality of dispersion spectra projected from the spectroscopic element and projected in the row direction;
an acquisition unit configured to acquire spectroscopic information of at least any of the plurality of test substances based on an output signal from the imaging unit; and
an intensification processing unit configured to perform row direction binning processing including integrating output signals of the plurality of light receiving elements existing at different positions in the row direction,
wherein the acquisition unit includes the intensification processing unit.
