Description

Technical Field

[0001] The utility model relates to the technical field of optical lenses, in particular to a lens. Background Art

[0002] In the application of optical lenses, their inherent properties may lead to performance compromises. For example, light will be reflected when passing through the interface of different media, which will reduce the amount of light passing through the lens and affect its light transmittance.

[0003] In addition, over time, lenses are subject to wear and tear from everyday use, which not only reduces their clarity but also shortens their lifespan.

[0004] At the same time, in normal life, water vapor condenses on the inside and outside of optical lenses due to temperature differences and humidity changes. Therefore, improving the performance of optical lenses through coating is an issue that needs attention. Utility Model Content

[0005] In view of the technical problem that the hardness performance, light transmittance performance and anti-fog performance of lenses need to be improved, the utility model provides a lens having the advantages of improving the hardness performance, light transmittance performance and anti-fog performance of the lens.

[0006] The technical solution of the utility model is:

[0007] A lens, comprising:

[0008] Anti-fog layer, resin layer, anti-reflection layer, wear-resistant layer and anti-fouling layer;

[0010] The thickness of the anti-reflection layer is 90 nanometers to 95 nanometers.

[0011] Optionally, an anti-reflection layer is provided on both sides of the resin layer.

[0012] Optionally, the two anti-reflection layers have the same thickness.

[0016] The anti-fog layer and the anti-reflection layer are arranged on the concave side of the resin layer.

[0017] Optionally, the wear-resistant layer has a thickness of 0.65 micrometers to 0.7 micrometers.

As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] Example:

[0026] See also Figure 1A lens comprises an anti-fog layer 1, a resin layer 2, an anti-reflection layer 3, a wear-resistant layer 4 and an anti-fouling layer 5 which are stacked in layers in sequence, wherein the anti-fog layer 1 is located in the inner layer and the anti-fouling layer 5 is located in the outer layer.

[0027] Specifically, the wear-resistant layer 4 is a silicon atomic layer, and the thickness of the wear-resistant layer 4 is 0.6 micrometers to 0.8 micrometers. If the thickness of the wear-resistant layer 4 is greater than 0.8 micrometers, the light transmittance of the entire lens decreases, affecting the optical performance of the lens. If the thickness of the wear-resistant layer 4 is less than 0.6 micrometers, the wear resistance of the wear-resistant layer 4 is insufficient to protect the lens. The wear-resistant layer 4 is further preferably 0.65 micrometers to 0.7 micrometers thick.

[0028] The anti-reflection layer 3 uses MgF2 as an anti-reflection material, and the thickness of the anti-reflection layer 3 is 90 nanometers to 95 nanometers, allowing light with a wavelength in the range of 500-520 nanometers to pass through.

[0029] The material used for the anti-fog layer 1 is PET anti-fog film, which is a transparent polymer film with good optical transparency and anti-fog performance. It can be coated on the surface of resin, glass, plastic, metal and other materials to prevent the generation of water mist or dew in a humid environment, thereby maintaining the clarity and transparency of the surface.

[0030] The material used for the anti-fouling layer 5 is PVDF (polyvinylidene fluoride) modified with hyperbranched polyglycerol brushes. By introducing hyperbranched polyglycerol brushes on the surface of the PVDF membrane, a highly anti-fouling separation membrane is constructed to effectively prevent the adsorption of dirt and achieve a higher anti-fouling effect.

[0031] In this embodiment, the resin layer 2 is a matrix, a wear-resistant layer 4 is introduced on the resin layer 2 to enhance the wear resistance, an anti-reflection layer 3 is introduced to improve the transmittance, and an anti-fog layer 1 is introduced to prevent fogging on the lens.

[0032] Preferably, an anti-reflection layer 3 is disposed on both sides of the resin layer 2, and the thickness of the two anti-reflection layers is equal, and the thickness of the anti-reflection layer is 92 nanometers. When MgF2 is used as the anti-reflection material and the thickness is 92 nanometers, light with a wavelength of 512 nanometers is allowed to pass.

[0033] Preferably, the anti-fog layer 1 is also provided with a wear-resistant layer 4 on the side away from the anti-reflection layer 3, and the thickness of the two wear-resistant layers 4 is the same. The wear-resistant layer 4 disposed between the anti-reflection layer 3 and the anti-fouling layer 5 is a silicon atom layer, and the wear-resistant layer 4 disposed on the inner side of the anti-fog layer 1 is a silicon dioxide layer.

[0034] Preferably, the resin layer 2 is an arc-shaped structure, and a convex side thereof is provided with an anti-reflection layer 3, a wear-resistant layer 4 and an anti-fouling layer 5, and a concave side of the resin layer 2 is provided with an anti-fog layer 1 and an anti-reflection layer 3.

[0035] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
