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.
