Description

Technical Field

[0001] This utility model belongs to the field of lenses, specifically, it relates to a novel high-refractive-index optical lens. Background Technology

[0002] Traditional high-refractive-index lenses often rely on a single material (such as 1.74 refractive-index resin), which suffers from problems such as high material brittleness and low Abbe number (severe dispersion). Although existing coating technologies can improve light transmittance, the number of layers is fixed (usually 5-7 layers), making it difficult to achieve gradient control of the refractive index. Utility Model Content

[0003] In view of this, the technical problem to be solved by this utility model is to provide a new type of high refractive optical lens that forms a continuous refractive index gradient by alternately stacking 8-16 layers of high and low refractive materials, effectively suppressing interface reflection and making it more suitable for the wearer.

[0004] To solve the above-mentioned technical problems, this utility model discloses a novel high-refractive-index optical lens, comprising: a substrate layer, a gradient refractive layer provided on the outer side of the substrate layer, the gradient refractive layer comprising a high-refractive-index layer and a low-refractive-index layer, the gradient refractive layer being composed of 8-16 layers of alternating high-refractive-index layers and low-refractive-index layers, the refractive index difference between adjacent layers being Δn=0.15-0.30, the refractive index of the high-refractive-index layer and the low-refractive-index layer decreasing layer by layer, a transition layer provided on the outer side of the gradient refractive layer, and a surface protective layer provided on the outer side of the transition layer.

[0005] According to one embodiment of the present invention, the high refractive layer is a zinc sulfide layer and the low refractive layer is a silicon dioxide layer.

[0006] According to one embodiment of the present invention, the transition layer is a silicon nitride layer with a thickness of 10-50 nm.

[0007] According to one embodiment of the present invention, the above-mentioned surface protective layer is a diamond-like carbon film layer.

[0008] Compared with the prior art, the present invention can achieve the following technical effects:

[0009] 1) By stacking 8-16 layers of high and low refractive index materials alternately, a continuous refractive index gradient is formed, which effectively suppresses interface reflection and makes it more suitable for the wearer.

[0010] Of course, any product implementing this utility model does not necessarily need to achieve all of the above technical effects at the same time. Attached Figure Description

[0015] 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.

[0016] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a novel high-refractive-index optical lens according to an embodiment of the present invention. As shown in the figure, a novel high-refractive-index optical lens includes: a substrate layer 10, a gradient refractive layer 20 disposed on the outer side of the substrate layer 10, the gradient refractive layer 20 including a high-refractive-index layer 21 and a low-refractive-index layer 22, the gradient refractive layer 20 being composed of 8-16 layers of alternating high-refractive-index layer 21 and low-refractive-index layer 22, the refractive index difference between adjacent layers Δn = 0.15-0.30, and the refractive index of the high-refractive-index layer 21 and the low-refractive-index layer 22 decreasing layer by layer.

[0017] In one embodiment of this utility model, a gradient refractive layer 20 is provided on the outer side of the substrate layer 10. The gradient refractive layer 20 includes a high refractive layer 21 and a low refractive layer 22. The high refractive layer 21 is a zinc sulfide layer and the low refractive layer 22 is a silicon dioxide layer. The gradient refractive layer 20 is composed of 8-16 layers of high refractive layer 21 and low refractive layer 22 stacked alternately. The refractive index difference between adjacent layers is Δn=0.15-0.30. The refractive index of high refractive layer 21 and low refractive layer 22 decreases layer by layer. Through the alternating stacking of 8-16 layers of high and low refractive materials, a continuous refractive index gradient is formed, which effectively suppresses interface reflection and makes it more suitable for the wearer.

[0018] Furthermore, a transition layer 30 is provided on the outer side of the gradient refractive layer 20, and a surface protective layer 40 is provided on the outer side of the transition layer 30.

[0019] In detail, a transition layer 30 is provided on the outside of the gradient refractive layer 20. The transition layer 30 is a silicon nitride layer with a thickness of 10-50nm, which reduces the temperature between the gradient refractive layer 20 and the surface protective layer 40 to prevent peeling due to excessive temperature. Then, a surface protective layer 40 is provided on the outside of the transition layer 30. The surface protective layer 40 is a diamond-like carbon film layer to protect the lens surface.

[0020] In summary, this invention forms a continuous refractive index gradient by alternately stacking 8-16 layers of high and low refractive materials, effectively suppressing interface reflection and making it more suitable for the wearer.
