Supernatural colors, sapphire glass

Sapphire glass generally refers to synthetic sapphire, which is very different from the jewelry we usually understand-natural sapphire. It is generally used for the manufacture of watch mirrors. Sapphire glass has good thermal properties, because it resists chemical corrosion, so it is resistant to high temperature, good thermal conductivity, high hardness, and good chemical stability. Therefore, it is often used to replace other optical materials to make optical components, so it is widely used in infrared and far-infrared military equipment, such as night vision cameras and other instruments and satellites, space technology instruments and meters, and as windows for high-power lasers. , Various optical prisms, optical windows, observation ports for low-temperature experiments, and most importantly, are also fully used in high-precision instruments and meters for navigation, aerospace, and aviation. The main advantage is that it is harder than ordinary glass and the price is relatively high, so it is mainly used to make high-end watch mirrors, so the relatively high price of watches with sapphire crystals is of course expected. Although the sapphire watch glass is man-made, its refractive index is the same as natural.

There are several ways to identify whether it is true: (1) Look at the logo. Because of the regular brand watches, the watch is usually printed on the dial or back cover of the watch. If these things do not exist, or if there is a counterfeit product, it is legally responsible. (2) Tap method. Tap the surface lightly with your fingers, there will be a dull sound (3) dripping method. Put a drop of water on the mirror surface of the watch. The water droplets on the mirror surface will have obvious effects of lotus leaves. The water drops will not spread. If the mirror surface of the watch is erected, the water drops will not spread out, and will slowly slide down. Water marks remain. Because the sapphire glass mirror surface is much smoother than the mirror surface of other materials, water droplets are not easy to spread on it, while other materials will disperse into one piece. This is the difference from other glasses.

Although the watch with sapphire glass mirror is more expensive, it must have its practical principles as the main material of the watch mirror. As the representative of the watch mirror material of high-end watches, if you want a good enough watch, then your first choice It must be a sapphire glass mirror.
