Abrasives and Slurries for the Optical Glass Market

Optical Glass

Like most industries, the optical glass market has been advancing to highly engineered and controlled processes that require tighter tolerances and specifications on finished end products.  This means that more than ever, the polishing uniformity has become very critical by controlling parameters like micro-waviness, surface roughness, and TTV.  In response to this challenging demand, Saint-Gobain Ceramic Materials has developed a line of high purity and discretely sized abrasives and slurries for the optical industry. 


Saint-Gobain Ceramic Materials' Specialty Abrasives group offers a wide range of abrasives (alumina, zirconia, ceria, colloidal silica) for lapping and polishing of many types of glass including:


  • Fused Silica
  • Pyrex
  • Phosphate Glass
  • Fused Quartz
  • Zerodur
  • High Lead Glass
  • Soda Lime Glass
  • Borofloat
  • BF-39, 42, 18, 3
  • BK-7
  • Filter Glasses
  • KG-1, NG-3, 4



Our specialty in nano-particle technology has opened possibilities to meet extremely demanding finishes in Angstrom levels that was once not possible with the traditional abrasive technology.
