Sapphire lenses are chemically inert and insoluble in water, common acids, or bases at temperatures up to approximately 1000 ° C. Can be used as a viewport to protect optical components, instruments, or other components in lasers. In some applications, optical windows need to withstand harsh environmental conditions and provide high levels of performance and reliability, with multiple unique characteristics that make them ideal materials for these applications. Sapphire window glass is a dual plane optical sapphire glass commonly used as a protective window for sensors and detectors. It does not alter the magnification of the system and has excellent surface hardness and a transmittance range from ultraviolet to mid infrared wavelengths.

1. Due to its structural strength, sapphire windows can be made thinner than other ordinary optical windows and have better light transmission performance.

2. The high thermal stability and excellent thermal conductivity make sapphire windows suitable for high-power applications, with less loss than other ordinary optical window plates.

3. Compared to most optical windows, sapphire windows can withstand higher temperatures and have zero degradation.

4. Sapphire lenses will not darken or lose their luster under ultraviolet radiation.

5. Due to the high dielectric constant of sapphire, the sapphire window is stable and can resist strong acid erosion.

6. Sapphire windows provide broadband transmission from ultraviolet to mid infrared (0.15-5.5 μ m), and these unique characteristics make them ideal materials for mechanical, chemical, and optical applications.

Sapphire lenses are synthetic sapphires made of alumina, with a chemical composition of Al2O3. They are a colorless and transparent crystalline material with the same refractive index as natural materials, and have good physical properties such as chemical corrosion resistance, high temperature resistance, high scratch resistance, and high hardness. It can effectively prevent scratches and impacts, and is widely used in the manufacturing of optical components, infrared and far-infrared equipment, high-density instruments and meters in the field of technology.
