Identification apparatus

An identification apparatus comprising:

• a conveyance unit including a plurality of conveyance trucks and configured to convey a plurality of test items in parallel;
• a first collecting unit corresponding to a truck of the plurality of trucks and a second collecting unit corresponding to another truck of the plurality of trucks;
• a first spectroscopic unit configured to disperse light from the first collecting unit;
• a second spectroscopic unit configured to disperse light from the second collecting unit;
• an imaging unit configured to acquire a first spectrum projected from the first spectroscopic unit and a second spectrum projected from the second spectroscopic unit, the imaging unit including a plurality of light receiving elements arranged at least in a first direction;
• and
• an acquisition unit configured to acquire information about the test items based on an output signal from the imaging unit,
• wherein an increase direction of a wavenumber of the first spectrum with respect to addresses of the light receiving elements in the first direction and an increase direction of a wavenumber of the second spectrum with respect to the addresses of the light receiving elements in the first direction are opposite to each other.
