Title: Particulate measuring device
Inventor: FUJITA HIROSHI
IPC: G01N15/14
Filed: 1996-04-02
Abstract: PROBLEM TO BE SOLVED: To reduce the fluctuation of transmittance of scattered light outgoing from an emission aperture so as to improve measuring accuracy by providing a polarizing plate for making a specific polarized component pass, between a laser oscillator and an incident aperture formed on one face of an airtight container. SOLUTION: At the time of filming bases 3 held in an airtight container 1, laser beams L formed in plane shape from a laser oscillator 7 through an optical means 8 pass a polarizing plate 9. The polarizing plate 9 makes only P-polarized components of the laser beams pass and enter into the airtight container 1 from an incident hole 4a through an incident aperture 4. The laser beams L therefore have only single polarized components so as to reduce the fluctuation of transmittance generated when scattered light S generated at the time of the laser beams L being hit by particulates P floating in the airtight container 1 is transmitted through a cover plate 26. When such scattered light S with little fluctuation is detected by a detecting part 11, a detection signal from the detecting part 11 is inputted to a counting part 14, and the number of floating particulates P can be measured.
