The invention provides a microparticle detecting device. The microparticle detecting device detects the size of the microparticles based on the Mie scattering theory, and reflects a main laser beam out of a diffused light beam propagation path by a reflecting component disposed on a main optical path of a laser, so that only a Mie scattered light is collected in the optical signal collected in thefinal optical receiver. According to the microparticle optical detecting device, by reducing the interference of the main laser beam to detection signals, noise during particle detection can be reduced and the signal-to-noise ratio can be improved; the scattering pattern of the obtained Mie scattered light is recorded and characterized, and the particles are marked to improve the accuracy of particle detection; and researchers can quickly and accurately detect the particles.
