  • Patent number: 8466435
    Abstract: A fine particle measuring device includes an optical filter that is divided into a plurality of areas and is disposed on an optical path on which light emitted from a fine particle, which is irradiated with light, is guided to an optical detector. In the fine particle measuring device, the optical filter includes a first area having wavelength selectivity by which the first area blocks reflected light from the fine particle and an unnecessary scattered light component and transmits fluorescence, and a second area that is disposed around at least the first area and has no wavelength selectivity so as to transmit a necessary scattered light component.
