The design of photoelectronic scanning machines for counting and sizing particles is discussed. Data are presented on the performance of a machine constructed for sizing particles dispersed on microscope slides. The size distribution of a sample of coal particles down to 5 μ as determined by the scanning machine agrees with that from a visual count.
