Abstract

Thin glasses having high refractive index (nd), a layer composite assembly made from these thin glasses, a method for the production of the thin glasses, and the uses of the thin glasses are provided. The thin glasses are processed in an in line manufacturing process and have the optical properties of a classical optical glass. The thin glasses are highly transparent, crystallization-resistant, chemically resistant and highly refractive. The viscosity/temperature behavior of the thin glasses is adjusted to the manufacturing process via in line flat glass methods.
