HIGHLY REFRACTIVE THIN GLASSES

摘要

Glass sheets with high refractive indexes (nd), layer composite assemblies including the glass sheets, methods for manufacturing the glass sheets, and methods of using the glass sheets are all provided. The glass sheets can be processed in a glass sheet manufacturing process and nevertheless have the optical properties of a classical optical glass. The glass sheets of the are highly transparent, resistant to crystallization, chemically resistant and highly refractive. The glass sheets have a viscosity-temperature behavior that is adapted to the manufacturing procedure with glass sheet manufacturing processes.
