Sapphire Window Products of Smart Phone Camera Lens Camera Glass

Description

Sapphire is the second strongest jewel on the Mohs mineral hardness scale, second only to the diamond. The crystal is usually made up of a sapphire-quartz combination. The screens are not completely shatter proof since strength is different than hardness, but it does mean that almost nothing other than diamond is able to scratch the face. This means that those who like to keep their watch faces completely scratch-free often go with this watch crystal.

Specification

The product shall be manufactured from high quality optical grade Czochralski grown color sapphire crystals.

Sapphire window film is also very common in life. In the fingerprint lock protective film industry, such as some mobile phone panels, fingerprint lock display panels, smart watch lenses, etc., its use is widely. The reasons for its popularity in the fingerprint lock protective film industry still have to be summarized in its high strength and high hardness. After all, who doesn't want high quality and not easy to damage, Even if the sapphire is not coated, it has excellent surface high hardness. It can't be rubbed, collided or scratched. If you deliberately damage it, there's no way, because no matter how high-quality materials can withstand manual damage; The transmittance range of this kind of window sheet can be extended from ultraviolet to mid infrared wavelength. Very few high hardness substances can scratch it. Moreover, the substrate of uncoated sapphire is also chemically inert. Even at 1000 ° C, it will not fuse with water, and common alkaline substances or acidic substances will not fuse, Even if some strong bases and acids are ignored, they can certainly be destroyed. Since most sapphire window sheets belong to the z-axis section, here, its c-axis side can be parallel to the optical axis, which avoids and eliminates the birefringence effect of transmitted light. At the same time, it is made into precision window sheets products, which can still be used in some laser fields and industrial fields.
