Description
Sapphire lenses are renowned for their exceptional durability, optical clarity, and resistance to extreme environments. With a broad transmission range from 0.15 to 5.5µm, they offer superior performance in UV, visible, and infrared applications, making them ideal for laser systems, thermal imaging, and high-precision optical instruments. Their Mohs hardness of 9 ensures outstanding scratch and abrasion resistance, significantly extending their lifespan compared to conventional glass lenses.
Additionally, sapphire’s chemical inertness makes it highly resistant to strong acids, corrosive gases, and extreme pressure or vacuum conditions, allowing for reliable operation in aerospace, defense, and industrial environments.
Engineered with precision, these lenses are available in concave, convex, and meniscus designs with tight tolerances, fine-ground edges, and premium surface quality, ensuring maximum light transmission and minimal optical distortion. Whether used in cutting-edge research, medical devices, or rugged industrial applications, sapphire lenses provide unparalleled performance and longevity in even the most demanding conditions.
