Sapphire and Silicon Carbide are two conventionally used optical materials.  Researchers around the world are investigating various techniques including mechanical polishing with fine abrasives and laser polishing to get these materials to an angstrom level surface finish.

• Ultrasmooth Finishing of Optics
• Polishing of Sapphire for Optical Applications
• Rapid Finishing of Optics
• Ultrafine SiC for Optical Mirrors
