    • The invention discloses a process for the production of a particulate polymer which contains few fine particles and has a narrow particle size distribution and a controlled bulk specific gravity. Characteristic features of the process of this invention reside in that a polymer latex obtained by emulsion polymerization is successively processed through the following steps (I) and (II):Step (I) The polymer latex is coagulated into a slurry in which particles thus coagulated are dispersed in water.Step (II) The slurry obtained in Step (I), an organic liquid almost insoluble in water and incapable of dissolving the polymer and water are mixed for granulation under the conditions that(a) The proportion of water in the whole mixture is 50-85 wt. %,(b) The amount of the organic liquid is 15-150 parts by weight per 100 parts by weight of the polymer in the polymer latex, and(c) The temperature T (.degree.C.) of the whole mixture is maintained for 0.5 minute to 1 hour on average within the range of the following equation:A-40.ltoreq.T.ltoreq.A wherein A means the azeotropic temperature (.degree.C.) of the mixture.In the above process, control of the interfacial tension between the organic liquid and the dispersion medium of the slurry within a specific range has made it possible to control the particle size of the resulting particulate polymer to a desired level.

    • A confocal scanning microscope including: an objective system (second objective lens 23 and objective lens 24) illuminating a sample SA with illumination light; a scanning mechanism 31 scanning the sample SA to obtain an intensity signal; and a scanning optical system 32 provided between the scanning mechanism and the objective system. The scanning optical system composed of, in order from the scanning mechanism side, a first positive lens group G1, a second negative lens group G2, and a third positive lens group G3. The third lens group has two chromatic aberration correction portions each formed by a positive lens and a negative lens or negative lens and positive lens. Glass materials are selected such that one performs chromatization and the other performs achromatization, thereby providing a confocal scanning microscope capable of correcting lateral chromatic aberration generated in the objective system in the specific wavelength region by the scanning optical system.
