Sapphire optical glass has excellent properties such as mechanical, optical, thermal, and chemical stability, which makes sapphire lenses suitable for aerospace or deep-sea applications.

We offer a variety of high-precision sapphire optical glasses, including convex lenses, concave lenses, and meniscus lenses. We also provide anti reflective coatings for sapphire lenses to improve efficiency in ultraviolet and infrared applications. The typical specifications of achievable sapphire lenses are: a diameter of up to 200 millimeters, a surface quality of up to 20/10, and a centering of up to arc seconds. Capable of polishing sapphire lenses with low roughness, high surface quality, and surface accuracy.
