FUSED SILICA MIRRORS

Our fused silica mirrors are manufactured from Corning 7980 or Industrial Grade Fused Silica, both of which provide a high degree of purity, exceptional environmental durability, and a low coefficient of thermal expansion.

Advanced Optics offers fused silica mirrors polished either λ/4, λ/10 or λ/20 to meet exact customer requirements. Many of our optical mirrors are available in-stock for immediate shipment.

Coatings include:

• Protected and bare aluminum
• Protected and bare gold
• Protected silver
• Aluminum magnesium fluoride
• Enhanced aluminum (one specifically designed for the visible region of the spectrum and one for the ultraviolet region)
• Custom optical coatings available upon request
