ROUND OPTICAL MIRRORS

Round optical mirrors are made from a variety of materials that are chosen based on their intended application. Advanced Optics produces round optical mirrors using high-quality materials such as BOROFLOAT® 33, SUPREMAX® 33, and fused silica, all manufactured in-house. In addition, we maintain a comprehensive inventory of other optical glass materials including N-BK7, Viosil, Zerodur, and Quartz, ensuring fast turnaround on your unique project.

Our in-stock optical mirrors are meticulously polished to achieve λ/4, λ/10, or λ/20, guaranteeing outstanding optical performance. They are offered with or without coatings, making them versatile for use as optical windows or flats.

Furthermore, our mirrors feature a robust aluminum coating with a protective SiO overcoat. We also provide customized coatings for specific spectral requirements, such as bare Al, enhanced aluminum, silver, and bare and protected gold coatings.

Target Grade - made of low-expansion borosilicate glass, which provides low thermal expansion, high thermal resistance, excellent light transmission, and impressive chemical durability.

Interferometer Grade - made of synthetic fused silica which provides superior transmission characteristics, a high degree of purity, exceptional environmental durability, and a low coefficient of thermal expansion.

ZERODUR® - made of a glass-ceramic material which is thermally more stable than fused silica.
