Schott ZERODUR® Glass Ceramic
Categories: Ceramic; Glass; Optical

Material Notes: ZERODUR® is a glass ceramic with an extremely low thermal expansion for demanding applications in which geometrical shape and distance changes must kept smallest possible under temperature variations. The key properties of ZERODUR® are:
  • Extremely low coefficient of thermal expansion (CTE) for a wide temperature range
  • Excellent CTE homogeneity throughout the total volume
  • Very low content of imperfections
  • Wide range of precise geometrical Shapes
  • Extremely smooth surface with residual roughness below 1 nm
  • Stages and mirrors for lithography equipment
  • Mirror substrates for segmented and monolithic large astronomical telescopes
  • Ultra light weighted mirror blanks
  • High precision mechanical parts, e.g. ring laser gyroscope bodies
  • Reference standards for precision measurement technology and comet probes
