Small thermal expansion for high-temperature applications
ZERODUR® K20 has been optimized to withstand higher application temperatures than ZERODUR®. The material is white in color and offers good infrared (IR) transmittance between 3.5 and 5 μm and homogeneous high reflectivity properties.
The non-porous ZERODUR® K20 exhibits good polishing abilities, excellent vacuum properties and can be delivered as small, high-precision optical components.
State of the art 5 axis CNC processing equipment and a variety of grinding technologies to produce complex geometries and filigree structures upon customer request.
State-of-the-art measurement equipment is used to inspect ZERODUR® K20 glass ceramic parts during the entire manufacturing process.
