With many applications in aerospace and other industries, glass ceramic is an extremely tough type of crystallized glass that serves as the foundation for Clear Glass Ceramic. While featuring the high transmittance required of optical devices, this advanced new material combines greater hardness than chemically strengthened glass and greater flexibility than sapphire crystal glass. These qualities make Clear Glass Ceramic the ideal material for protective lens filters.
 
Clear Glass Ceramic is made with a special heat treatment that precipitates microcrystals of a mineral called spinel evenly throughout, giving the entire filter consistent strength. Combining much greater hardness than chemically strengthened glass and greater flexibility than sapphire crystal glass, Clear Glass Ceramic is the ideal material for protective filters. Clear Glass Ceramic is also resistant to cracking due to small scratches or chips. Since the risk of shattering and producing fragments is reduced, it also offers an enhanced level of safety.
