sapphire crystalMainly used for mirror surfaces, many manufacturers need to be careful during the production process, especially during polishing. If done improperly, it can cause significant losses and affect the corporate image. During the preparation process, sapphire windows may appear slightly yellow in color, depending on the purity of the raw materials and the process parameters used in the preparation. Sapphire material contains trace impurities such as iron, titanium, and other elements, which may cause changes in window color. In addition, the processing and polishing during the preparation process may also affect the color.

However, the pale yellow color of the sapphire window did not have a significant impact on its optical properties. Sapphire still has excellent transparency and optical properties, capable of transmitting light in the visible and near-infrared spectral ranges. Therefore, unless color deviation has specific requirements for a particular application, a slight yellow deviation generally does not have a significant impact on functionality and performance. If a yellowish color is unacceptable for a specific application, high-purity sapphire material can be chosen or the window color can be improved through subsequent processing and handling, which may include further fine polishing or the application of special optical coatings to adjust the color.

The grinding stage of sapphire glass can be roughly divided into three stages: rough grinding, fine grinding, and polishing. Coarse grinding makes it uniform, while fine grinding makes it smooth. Precision machining stage: Polish it to look like a mirror. From these processes, it can be known that the polishing process of sapphire window panels is actually an etching and blowing process to achieve the desired state. Polishing is to make the various parts of the sapphire window (lens) achieve a mirror effect.

Sapphire is one of the hard and scratch resistant materials, suitable for applications that require high durability and wear resistance. Has excellent optical properties, high transparency, and low light scattering. This makes it an ideal material for lenses, windows, and other optical components. Despite its high initial cost, sapphire glass is an economically efficient material for many applications due to its long-term durability and low maintenance requirements.
