Zerodur® is a unique glass-ceramic material with a nearly zero coefficient of thermal expansion. Zerodur is an ideal material for environments with large temperature fluctuations.
All dielectric coating construction is physically more durable than standard metallic coatings. Dielectric mirrors are more resistant to humidity, thermal changes, abrasion and salt exposure. These durability of these multilayer dielectric coatings also makes them resistant to damage from repeated cleaning.
