Optical glass – in different shapes:
pressings, plates, bars, blocks

		We purchase our optical glass preferably from the Schott Glass Works. Of particular importance here are the optical properties of the different glass materials and their tolerances. When choosing our suppliers, we also take into account their delivery capabilities and delivery times, their prices and the environmental soundness of their products. In our optical production, we currently process 114 types of optical glass with different refractive indices, color
dispersion, weight, etc. This results in a spectrum of approx. 350 different types of lens elements with approx. 700 different radii. Each lens consists of several optical glass materials and crystals, with some almost as heavy as steel and others more expensive than gold. We mainly process pressings for serially produced camera lenses. Glass blocks are used for the production of prototypes and special components. The blocks are first cut into plates which are then rounded and further processed to produce lens elements.
