Chemical Microscopy in the Optical Industry

Source

Some improvements in equipment and techniques are described for the microscopic determination of the particle size of abrasives, polishing, buffing, and other materials encountered in the manufacture of glass optics and scientific instruments. Identification of these materials or of impurities present is facilitated by the use of dispersion-staining microscopy combined with polarizing accessories. Dispersion staining used alone or combined with the usual Becke line method has proven to be of value for the refractive index determination of experimental and production type glasses and certain plastics used in the optical industry.
