ZERODUR®

ZERODUR® glass ceramic is an inorganic, non-porous glass ceramic and has a completely non-directional, isotropic structure.

Due to the perfect balance of glass and crystal phases within the material, the thermal expansion coefficient is nearly zero.

We have a 300mm Zerodur Blank which would make a unique and fantastic mirror upgrade for any 300mm telescope.
