1. A bioparticle analyzer, comprising:
a scattered light detection system that includes:
an optical filter configured to separate scattered light from partial light in a laser beam, wherein
the scattered light is generated by irradiation of a bioparticle with the laser beam,
the bioparticle flows through a channel, and
the optical filter has wavelength selectivity;
an objective lens configured to receive the scattered light separated by the optical filter; and
a doublet lens, wherein the objective lens is between the optical filter and the doublet lens.
