Sapphire Lenses
Extremely hard and abrasion resistant: Sapphire has a hardness of nearly 9 on the Mohs scale, second only to diamond, so sapphire lenses have excellent scratch and wear resistance and maintain a surface finish in harsh environments.
High thermal conductivity: Sapphire has good thermal conductivity, which helps to quickly disperse heat inside the lens and prevent fluctuations in optical properties caused by temperature changes.
High Transmittance and Wide Spectral Range: Sapphire lenses have good transmittance in the ultraviolet (UV) to midwave infrared (MWIR) wavelength range, covering a wide spectral range and making them suitable for a wide range of optical applications.
Excellent chemical stability: Sapphire has excellent resistance to common chemical acids and bases, allowing it to be used in corrosive environments for long periods of time without damage.
Thin design: Due to its high hardness and structural strength, sapphire lenses can be designed to be thinner while maintaining sufficient mechanical strength and optical properties.
Applications: Laser technology, Infrared Optics, Aerospace, Medical Devices, Scientific research, etc.

Lenses are optical components utilized for focusing or diverging light. Sapphire Lenses are ideal for demanding applications (such as lasers) and harsh environments because of their extreme surface hardness, high thermal conduction, high dielectric constants, and resistance to common chemical acids and alkalis. Sapphire (Al2O3) is the second hardest crystal next to diamond, and because of their structural strength, sapphire crystal lenses can be made much thinner than other common materials. Sapphire has decent transmission rates from 0.15 to 5.5μm, which covers the ultraviolet (UV) to mid-wave infrared (MWIR) wavelength range.
