High-Strength Sapphire Watch Case with Good Thermal Stability and High Optical Transmission

 

 

Material: Synthetic sapphire are real sapphires grown in labs. They are created by duplicating the environmental conditions that naturally mined stones are formed within. Lab-created sapphires are chemically identical to mined sapphires, but they are produced in a laboratory setting. Synthetic sapphires are the hardest of all known oxide crystals, second only to diamond in hardness.

FATURES

 

1. High mechanical strength: the permeable infrared window material should have sufficient strength to withstand the high-speed movement of the speed pressure load;


2. Good thermal stability: the permeable infrared window material should be able to withstand the temperature shock caused by pneumatic heating and height changes, transmission ratio and refractive index should not change significantly with the change of temperature;


3. Good chemical stability: through infrared window material exposed to air, should be able to prevent the atmospheric salt solution or corrosion gas corrosion, and not easy to moisture;


4. High optical transmission rate, must be able to effectively transmit ultraviolet to medium infrared radiation;


5. Good optical characteristics, small optical scattering and good uniformity of refractive index;
Meets large window requirements.
