Description

Technical Field

[0001] This utility model belongs to the field of lens technology, specifically, it relates to a long-lasting, high-temperature resistant, and film-crack resistant lens. Background Technology

[0002] To meet the optical performance requirements of resin lenses, a coating is typically applied to the surface of the resin lens to reduce light reflection and enhance light transmission. However, due to differences in the physicochemical properties between the substrate and the coating materials of the resin lens, or between different coating layers, existing resin lenses often lack good high-temperature resistance. Consequently, they are prone to blistering or coating peeling on the lens surface under high-temperature or alternating hot and cold environments, especially in summer when the coating is prone to cracking inside a car.

[0003] Therefore, there is a need for a lens that can still maintain long-term high-temperature resistance and film crack resistance in high-temperature environments. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is to provide a long-lasting high-temperature resistant and film-crack resistant lens, so as to avoid the problem of insufficient high-temperature resistance of previous lenses, especially the easy film cracking under high-temperature environment.

[0005] To solve the above-mentioned technical problems, this utility model discloses a long-lasting, high-temperature resistant, and crack-resistant lens, which includes:

[0006] Resin substrate;

[0007] A hardening layer dipped onto the surface of a resin substrate;

[0008] A blue light blocking layer plated onto the surface of the hardened layer;

[0009] A high refractive index film coated on the surface of the blue light blocking layer;

[0010] A crack-resistant film layer group is set on the surface of a high refractive index film layer. The crack-resistant film layer group is composed of a silane film layer, a high-temperature resistant film layer, and a magnesium fluoride film layer in sequence.

[0012] According to one embodiment of the present invention, the silane film layer is spin-coated onto the surface of a high refractive index film layer, and the magnesium fluoride film layer is deposited by vacuum sputtering.

[0013] According to one embodiment of the present invention, the thickness of the high-temperature resistant film layer is set to 20-120 μm.

[0014] According to one embodiment of the present invention, the high refractive index film layer is configured as a silicon dioxide film layer and an aluminum oxide film layer, and the refractive index is 1.7 or higher.

[0015] Compared with the prior art, the present invention can achieve the following technical effects:

[0016] A crack-resistant film layer group is formed by setting a silane film layer, a high-temperature resistant film layer, and a magnesium fluoride film layer. The silane film layer is formed by spin coating to form the bottom layer, the middle high-temperature resistant film layer enhances the high-temperature resistance, and the outer magnesium fluoride film layer has a high melting point and good optical properties, providing good protection.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. Attached Figure Description

[0022] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0023] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a long-lasting, high-temperature resistant, and film-crack resistant lens according to an embodiment of the present invention.

[0024] As shown in the figure, a long-lasting high-temperature resistant and crack-resistant lens includes: a resin substrate 10; a hardening layer 20 coated on the surface of the resin substrate 10; a blue light blocking layer 30 plated on the surface of the hardening layer 20; a high refractive index film layer 40 plated on the surface of the blue light blocking layer 30; and a crack-resistant film layer group 50 disposed on the surface of the high refractive index film layer 40, wherein the crack-resistant film layer group 50 is sequentially configured as a silane film layer 51, a high-temperature resistant film layer 52, and a magnesium fluoride film layer 53.

[0025] In one embodiment of this utility model, the resin substrate 10 is formed by resin curing, and a hardening layer 20 is formed on its surface by immersion coating with a hardening liquid to improve the surface hardness of the resin substrate 10. The hardening layer 20 can be an organosilicon film layer. The blue light blocking layer 30 is deposited by a coating machine to improve the blue light blocking effect of the lens. A silicon dioxide film layer or other metal oxide film layer can be selected for deposition.

[0026] A high refractive index film 40 is deposited on the surface of the blue light blocking layer 30 to improve the refractive index of the lens.

[0027] A crack-resistant coating layer 50 is disposed on the outermost layer of the lens and consists of a silane coating layer 51, a high-temperature resistant coating layer 52, and a magnesium fluoride coating layer 53. The silane coating layer 51 is spin-coated onto the surface of the high-refractive-index coating layer 40, providing excellent heat resistance and serving as an adhesion base layer to improve the adhesion of the high-temperature resistant coating layer 52. The magnesium fluoride coating layer 53 is vacuum sputtered to form an outer protective layer. The intermediate high-temperature resistant coating layer 52 significantly enhances high-temperature resistance, preventing the coating from cracking under high temperatures.

[0028] Specifically, the high-temperature resistant film layer 52 has 9 layers, including a silicon dioxide film layer, a titanium dioxide film layer, a silicon dioxide film layer, a titanium dioxide film layer, a silicon dioxide film layer, a zirconium dioxide film layer, a silicon dioxide film layer, a zirconium dioxide film layer, and a silicon nitride film layer deposited sequentially. The 9 layers are vacuum deposited sequentially and have a high melting point, good chemical stability and mechanical strength, which greatly improves the high-temperature resistance of the lens.

[0029] Preferably, the thickness of the high-temperature resistant film layer 52 is set to 20-120μm to ensure the strength of the film layer.

[0030] In addition, the high refractive index film 40 is composed of a silicon dioxide film and an aluminum oxide film, with a refractive index of 1.7 or higher, which improves the refractive index of the lens and reduces the interference of stray light.

[0031] In summary, this invention comprises a silane film layer, a high-temperature resistant film layer, and a magnesium fluoride film layer to form a crack-resistant film layer group. The silane film layer is formed by spin coating to form the underlying layer, the middle high-temperature resistant film layer enhances the high-temperature resistance, and the outer magnesium fluoride film layer has a high melting point and good optical properties, providing good protection.
