1. A particle detection apparatus comprising:
a plurality of optical detectors configured to detect light from a particle, each of the plurality of optical detectors having a respective applied voltage coefficient, wherein at least one of the plurality of optical detectors has the applied voltage coefficient higher than a predetermined applied voltage coefficient of the plurality of optical detectors; and
a processor including a processing device and a memory storing instructions that, when executed by the processing device, cause the processor to:
correct optical data obtained by the plurality of optical detectors from the particle in accordance with a difference between the respective applied voltage coefficient for each of the plurality of optical detectors and the predetermined applied voltage coefficient.
