Zerodur a registered trademark of Schott AG, is a lithium-aluminosilicate glass- ceramic produced by Schott AG since It has been used for a number of very. a metal bench and then control the spectrometer thermal environment to milli- Kelvin levels. An alternative approach used by KPF is to employ a Zerodur bench . Figure 5 shows the peak acceleration spectral density (ASD). Zerodur is a registered trademark of Schott Glass Technologies. Dispersion: (nf - nc) = ; Density: g/cm3 at 25°C; Young's Modulus: x Zerodur® is a glass ceramic with an extremely low thermal expansion coefficient. Property, Value*. Density, gm/cc. Hardness, The dimensional instability is discussed as an increase in Zerodur density. Metal mirrors and single-phase materials do not exhibit such catastrophic.
