Accurately sized PSL spheres of several diameters are deposited on disks. Scatter from the depositions is measured and compared to the results of a model for surface bound particles. The results are important for two reasons. The measurements will help provide an early database for determining the smallest detectable particles for a given disk texture. Secondly, the use of these particular PSL spheres, which have been accurately sized to about 1% of their diameter, will be important for establishing particle standards for the disk industry.
