Zerodur Optical Mirrors
Optical mirrors made of Zerodur provide a very low coefficient of thermal expansion making this glass-ceramic material ideal for applications where the optical mirror is exposed to fluctuating and/or extremely cold temperatures. Although Zerodur has a yellowish overall tint, it has good homogeneity for mirror applications where bubbles or inclusions are a concern.
Advanced Optics manufactures precision polished optical mirrors made of Zerodur flat up to 1/20 wave. Standard coatings include protected and bare aluminum, protected and bare gold, protected silver, aluminum magnesium fluoride, and enhanced aluminum (one specifically designed for the visible region of the spectrum and one for the ultraviolet region). Custom coatings available upon request.
