About Optical Glass
Our optical glasses cover the requirements of numerous applications from consumer optics to optical systems in research and development. All glasses were treated by our sophisticated annealing process and brought into a state with precisely defined optical properties. Our annealing process achieves very low values of stress birefringence with homogeneous refractive index distribution. The fine annealed optical glass is available in strips or blocks, which can be used for cold postprocessing.
In addition, we offer “P”-glass for the precision molding process (Low Tg glass). This glass is in a coarse annealed state.
