- Quartz glass is the general name for glass made out of SiO2. There are different manufacturing processes and also naturally occurring quartz glass.
- Raw forms for optical applications are bars or ingots, plates larger than 1m x 1m are also possible
- Further characteristics:
- high permeability for IR - UV radiation
- a very low coefficient of thermal expansion
- high thermal shock resistance with continuous use up to 1,100 ° C
- a high softening temperature
- high chemical resistance
- a high dielectric strength
