Product Case Studies

Sapphire has excellent surface hardness and a transmittance range extending from ultraviolet to mid infrared wavelengths. Sapphire can only be scratched by a few substances other than it. Uncoated substrates are chemically inert and insoluble in water, common acids, or bases even at temperatures up to approximately 1000 ° C. Our sapphire window has a z-axis section, so the c-axis of the crystal is parallel to the optical axis, eliminating the birefringence effect of transmitted light.

Physical and optical properties

• High hardness and wear resistance：The Mohs hardness of sapphire is about 9, second only to diamond, which gives sapphire window plates excellent wear and scratch resistance.
• Broad spectral transmittance：Sapphire has good transparency in a wide spectral range from ultraviolet (about 190 nm) to mid infrared (about 5000 nm).
• High thermal conductivity：Sapphire has a high thermal conductivity, which enables it to effectively dissipate heat in high-temperature applications.
• chemical stability：Sapphire has extremely high resistance to most acidic, alkaline, and corrosive environments, making it suitable for applications in harsh environments.
• High strength and toughness：Sapphire has high mechanical strength and good toughness, allowing it to withstand high pressure and impact.

application area

• High performance window：Sapphire window panels are widely used in applications that require high strength, high wear resistance, and chemical stability, such as high-pressure observation windows, high-speed aircraft windows, etc.
• LASER SYSTEM：In laser systems, sapphire window plates are used to protect lasers and other optical components, especially in harsh environments.
• Infrared and ultraviolet optical systems：Due to its wide spectral transmittance, sapphire window plates are suitable for windows and lenses in infrared and ultraviolet optical systems.
• High temperature and high pressure applications：The high thermal stability and strength of sapphire make it an ideal window material for high temperature and high pressure environments.
