Sapphire Window Products of Smart Phone Watch Lens Watch Glass
Description
There are many modern examples of using sapphire crystals as screens in watches and other devices. Sapphire is tough, but it takes delicate work during machining. Such watches often take 1,000 hours of machining with up to 430 hours pre-forming case components and another 350 just for watch case polishing. Watches with sapphire crystals can often cost between $100 and $300 or more depending on the watch. They are also a common addition to diving watches due to their clearness and toughness despite water pressure of 50 meters or more.

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.
