ZERODUR®, the extremely low expansion glass ceramic from SCHOTT, delivers extremely high precision for many challenging high-tech applications such as IC and LCD lithography, high-precision measurement and astronomy – for all demanding applications in which geometrical shape and distance changes must be minimized as much as possible during shifts in temperature.  ZERODUR® is an inorganic, non-porous lithium aluminium silicon oxide glass ceramic characterized by evenly-distributed nano-crystals within a residual glass phase.  It can be provided as small finished components, as ultra-light weight mirror substrates, but also as mirror substrates for large segmented and monolithic astronomical telescopes.
