Embodiment 1

[0017] The preparation method of the glass lens 1 with the sapphire surface layer is as follows:

[0018] Using metal aluminum as a target, nitrogen as a sputtering gas, a glass lens as a substrate, and oxygen as a reactive gas, the target is sputtered to form a sapphire film on the substrate. The sapphire The thin film is an aluminum oxide thin film, wherein the deposition temperature is controlled to be 400° C., the deposition total pressure is 0.8 Pa, and the oxygen partial pressure is 2%.

[0019] The target material is non-doped high-purity metal aluminum with a purity of 99.99%.

[0020] The purity of the oxygen is 99.99%, and the purity of the nitrogen is 99.99%.

Embodiment 2

[0022] The preparation method of the glass lens 2 with a sapphire surface layer uses metal aluminum as a target material, nitrogen as a sputtering gas, a glass lens as a substrate, and oxygen as a reactive gas to sputter the target material so that the A sapphire film is formed on the substrate, and the sapphire film is an aluminum oxide film, wherein the deposition temperature is controlled to be 600° C., the deposition total pressure is 3.0 Pa, and the oxygen partial pressure is 6%.

[0023] The target material is non-doped high-purity metal aluminum with a purity of 99.99%.

[0024] The purity of the oxygen is 99.99%, and the purity of the nitrogen is 99.99%.

Embodiment 3

[0026] The preparation method of the glass lens 3 with a sapphire surface layer uses metal aluminum as a target material, nitrogen gas as a sputtering gas, a glass lens as a substrate, and oxygen as a reactive gas to sputter the target material so that the A sapphire film is formed on the substrate, and the sapphire film is an aluminum oxide film, wherein the deposition temperature is controlled to be 500° C., the deposition total pressure is 2.0 Pa, and the oxygen partial pressure is 4%.

[0027] The target material is non-doped high-purity metal aluminum with a purity of 99.99%.

[0028] The purity of the oxygen is 99.99%, and the purity of the nitrogen is 99.99%.

[0029] The prepared glass lens 1 with a sapphire surface, the glass lens 2 with a sapphire surface, and the glass lens 3 with a sapphire surface not only enhance the surface hardness of the glass, but also greatly reduce the cost, and also break the low production capacity of the sapphire lens. Limitations, can ...

Abstract

The invention discloses a glass lens with a sapphire surface layer. The glass lens comprises a glass lens body and a sapphire film attached to the glass lens body. The invention also provides a preparation method of a glass lens with a sapphire surface layer. The preparation method comprises the following steps: taking metallic aluminium as a target material, nitrogen as a sputtering gas and a glass lens as a substrate, and taking oxygen as a reaction gas to sputter the target material so as to form a sapphire film on the substrate, wherein the sapphire film is an aluminium oxide film. The glass lens with the sapphire surface layer and the preparation method thereof are advantageous in that, the feasibility and the continuity of sapphire glass coating are achieved; when a common glass lens is plated with the sapphire film, not only is the surface hardness of glass enhanced, but also the cost is greatly lowered; meanwhile, the limitation of low productivity of sapphire lenses is broken; and the productivity of substitute products of the sapphire lenses can be greatly improved. The preparation method of the glass lens with the sapphire surface layer is simple.

Description

technical field [0001] The invention relates to a glass lens with a sapphire surface layer, and also relates to a preparation method of the glass lens with a sapphire surface layer. Background technique [0002] At present, most of the high-end watch glass lenses on the market are sapphire lenses, which are relatively expensive. If ordinary glass lenses are used, they cannot meet the hardness requirements and are easy to scratch. [0003] There is also a common tempered glass on the market, but its surface hardness is relatively low, which cannot meet the customer's requirements for glass hardness. [0004] With the market of capacitive screens such as mobile phones and tablet computers becoming more and more mature, their processing technology is constantly updated and improved. The general production process and level are far from meeting the requirements of customers. Apple took the lead in introducing touch screen panels and camera protection sheets based on sapphire, a...
