Sapphire glass is usually used to make high-end watch mirrors, mobile phone screens and other products. Using sapphire glass as a watch mirror is a very popular processing technology. It has high transparency, high cost performance, scratch resistance, and good hardness. It is a relatively good mirror material.
Sapphire glass is not blue, it can be changed into various colors by adding some chemical agents, but generally speaking, sapphire glass is often made colorless, used to make high-end watch mirrors, mobile phone screens, and wear The device screens are very suitable.
In addition, the sapphire glass material has the characteristics of electrical insulation and thermal conductivity, good chemical stability, and good infrared penetration. It is widely used in all aspects of infrared military equipment, such as far-infrared sights, night vision cameras, etc.
Consumer electronics products continue to be updated every year, constantly trying new technologies, new functions, and new applications. Even though sapphire glass is currently only used for camera slides, watches, and wearable product screens, small-format sapphire is used, but With the maturity of technology, the decline in usage costs, and the new requirements of consumer experience, the use of sapphire full screens in smart phones in the future is also an important choice.
Laser cutting has become the best choice for processing sapphire lens caps. Nowadays, the price of lasers has dropped significantly, and almost no one considers nanosecond lasers for cutting, so ultrafast lasers have become the primary consideration. The picosecond pulse can reduce the occurrence of cracks, and the cutting quality far exceeds that of ordinary milling. The laser beam sweeps the processed material multiple times to achieve cutting.
In the past, some equipment that can achieve sapphire cutting on the market mainly used infrared picosecond lasers. In the future, it may be done with ultraviolet picoseconds or even femtosecond lasers.
The technology of sapphire laser processing application still cannot be given up, and more work is needed to pave the way for the mass application of sapphire glass in the future. Only when mature technology and solutions are prepared can we meet new market opportunities
