Sapphire materials are divided into Kyrgyzstan method, heat exchange method, guided mode method and flame method.

Among them, the Kyrgyzstan method comes from Russia, the heat exchange method is most commonly used in the United States, the guided mode method is mostly used in Japan, and the flame method first originated in Switzerland.

Table mirror sapphire window (commonly known as table cover), flame method materials are used more;

For consumer sapphire windows (such as mobile phones, tablet devices, fingerprint identification devices), the guided mode method is used more;

Large-size window, no strict requirements on optical performance, heat exchange method can be used;

If the optical requirements are strict and there are few internal defects in the material, the Kyrgyzstan method can only be selected.

The sapphire optical windows produced by Taixing Hechen Crystal Technology Co., Ltd. all use Kyrgyzstan method materials.
