Description

Technical Field

[0001] The utility model relates to the technical field of optical lenses, in particular to an anti-reflection film light imaging optical lens. Background Art

[0002] Optical glass is a mixture of high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, and barium, mixed according to a specific formula. It is then melted at high temperature in a platinum crucible, stirred evenly with ultrasound to remove air bubbles, and then slowly cooled over a long period of time to prevent internal stress in the glass. The cooled glass must be measured with optical instruments to verify that its purity, transparency, uniformity, refractive index, and dispersion meet specifications. Qualified glass blocks are then heated and forged into optical lenses. Anti-reflection (AR)-coated optical imaging lenses are a special type of optical component. Their primary function is to reduce reflection losses on the lens surface and increase the intensity of transmitted light by coating the lens surface with a thin, transparent dielectric film, thereby achieving clearer imaging. Existing AR-coated optical imaging lenses are made of fragile materials. When subjected to strong impact, such as when dropped, they can easily shatter and cause glass fragments to fly, making them somewhat dangerous.

[0003] In view of the above problems, the present invention proposes an anti-reflection film light imaging optical lens. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-reflection film light imaging optical lens, thereby solving the problem that the existing anti-reflection film light imaging optical lens is easily broken and glass fragments are splashed when subjected to a strong impact force, such as falling to the ground, thus posing a certain risk.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-reflection film light imaging optical lens, comprising a lens body mounted on the inner wall of an external lens barrel, with an optical lens A and an optical lens B respectively disposed at either end of the lens body, a first anti-reflection film assembly bonded between the optical lens A and the lens body, and a second anti-reflection film assembly bonded between the optical lens B and the lens body. The first anti-reflection film assembly and the second anti-reflection film assembly have the same composition structure, and the first anti-reflection film assembly and the second anti-reflection film assembly are symmetrically distributed about the center of the lens body;

[0006] The first antireflection film assembly includes an antireflection film layer, one end of the antireflection film layer is bonded to a first adhesive layer, and one end of the antireflection film layer away from the first adhesive layer is bonded to a second adhesive layer.

[0007] Furthermore, the first adhesive layer and the second adhesive layer are both symmetrically distributed about the center of the antireflection film layer.

[0008] Furthermore, the first adhesive layer and the second adhesive layer are both made of highly transparent resin material.

[0009] Furthermore, the end of the optical lens A away from the first anti-reflection film assembly is bonded with a first anti-fog layer, and the end of the optical lens B away from the second anti-reflection film assembly is bonded with a second anti-fog layer.

[0010] Furthermore, the first anti-fog layer and the second anti-fog layer are both symmetrically distributed about the center of the lens body.

[0011] Furthermore, the first anti-fog layer and the second anti-fog layer are both made of polymer materials.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model provides an anti-reflection film light imaging optical lens. When the lens is subjected to a strong impact and causes the lens to break, the first adhesive layer and the second adhesive layer made of a highly transparent resin will adhere to the glass fragments, thereby preventing the glass fragments from flying, improving safety, and solving the problem of existing anti-reflection film light imaging optical lenses. Since the lens itself is made of fragile materials, when subjected to a strong impact, such as falling to the ground, it is easy to cause the lens to break and glass fragments to fly, thus posing a certain risk.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-Figure 4 In order to solve the problem that the existing anti-reflection film optical imaging lens is made of fragile materials, when it is subjected to strong impact, such as falling to the ground, it is easy to cause the lens to break and glass fragments to fly, thus posing a certain risk, the following preferred technical solutions are provided:

[0021] A light imaging optical lens with an antireflection film comprises a lens body 2 mounted on the inner wall of an outer lens barrel 1, with an optical lens A3 and an optical lens B4 respectively provided at both ends of the lens body 2, a first antireflection film component 5 bonded between the optical lens A3 and the lens body 2, and a second antireflection film component 6 bonded between the optical lens B4 and the lens body 2, the first antireflection film component 5 and the second antireflection film component 6 have the same composition structure, and the first antireflection film component 5 and the second antireflection film component 6 are symmetrically distributed about the center of the lens body 2, the first antireflection film component 5 comprises an antireflection film layer 51, one end of the antireflection film layer 51 is bonded with a first adhesive layer 52, and the end of the antireflection film layer 51 away from the first adhesive layer 52 is bonded with a second adhesive layer 53, the first adhesive layer 52 and the second adhesive layer 53 are both symmetrically distributed about the center of the antireflection film layer 51, and the first adhesive layer 52 and the second adhesive layer 53 are both components made of highly transparent resin material.

[0022] The end of the optical lens A3 away from the first anti-reflection film assembly 5 is bonded with a first anti-fog layer 7, and the end of the optical lens B4 away from the second anti-reflection film assembly 6 is bonded with a second anti-fog layer 8. The first anti-fog layer 7 and the second anti-fog layer 8 are both symmetrically distributed about the center of the lens body 2. The first anti-fog layer 7 and the second anti-fog layer 8 are both components made of polymer materials.

[0023] Specifically, the highly transparent resin material has high transparency, so that the appearance of the object after bonding or encapsulation is clear, and does not affect the effect of the lens body 2. If the lens is broken by a strong impact, the first adhesive layer 52 and the second adhesive layer 53 of the highly transparent resin material will adhere to the glass fragments, thereby preventing the glass fragments from flying, improving safety, and solving the problem of existing anti-reflection film light imaging optical lenses. Since the lens itself is made of fragile materials, when it is subjected to a strong impact, such as falling to the ground, it is easy to cause the lens to break and glass fragments to fly, so it has certain dangers.

[0024] The first anti-fog layer 7 and the second anti-fog layer 8 made of polymer material can effectively prevent water mist condensation, so that water droplets form a uniform film on the surface without condensing into mist. This feature ensures that the transparent material can still maintain a clear field of vision in a humid environment, thereby improving the safety and comfort of use.
