Description

Optical lens

Technical Field

The present invention relates to an optical element, and more particularly to an optical lens.

Background

In the optical imaging lens, a light beam incident into the optical lens assembly at a large angle is easily reflected or refracted by the edge of one or more optical lenses to form stray light. The astigmatism mentioned above can negatively affect the imaging of the optical lens.

SUMMERY OF THE UTILITY MODEL

In order to overcome the above disadvantages, an object of the present invention is to provide an optical lens, which improves the structure of the optical lens and avoids the influence of the astigmatism formed at the edge on the optical imaging.

In order to achieve the above purpose, the utility model discloses a technical scheme is: an optical lens comprises a lens body, wherein the lens body comprises an optical part and a peripheral part, the optical part is located at the central position, the peripheral part surrounds the optical part, and a color-changing membrane is arranged on an arc convex surface of the optical part; the connecting part of the optical part and the peripheral part is a connecting surface, an opacifier layer is arranged on the connecting surface, taper holes are distributed on the surface of the peripheral part in an array mode, and the cross section of each taper hole is an obtuse angle.

Preferably, the maximum depth of the taper hole is between 0.5mm and 1 mm.

Preferably, the distance between two adjacent taper holes is between 2mm and 4 mm.

Preferably, the lens body is formed of a glass or resin material.

Further, the surface of the peripheral part is an inclined plane, and the thickness of the inclined plane is gradually reduced from inside to outside; the included angle between the inclined plane and the horizontal plane is 1-5 degrees.

Preferably, the outer edge of the peripheral portion is provided with a tangent plane.

Through the design of the inclined plane and the tangent plane, the optical lens can be conveniently cut.

Compared with the prior art, the utility model discloses an increase the light-screening agent layer and avoid outside light to directly penetrate into optical part from joining face department on joining the face, the obtuse taper hole of array distribution simultaneously on peripheral portion makes the light that is located peripheral portion internal scattering and the taper hole contact after can scatter the optical lens outside to avoid the astigmatism to the influence of central authorities optical part formation of image.

Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Examples

Referring to fig. 1 and fig. 2, an optical lens in the present embodiment includes a lens body 1, where the lens body 1 is made of glass or resin material; the lens body 1 comprises an optical portion 11 located at the central position and a peripheral portion 12 surrounding the optical portion 11, wherein a color-changing membrane is arranged on an arc-shaped convex surface of the optical portion 11, and can filter a part of blue light to reduce damage to eyes. The joint of the optical part 11 and the peripheral part 12 is a joint surface 13, and the joint surface 13 is provided with a light-shading agent layer to prevent external light from directly entering the optical part 11 from the joint surface 13. Taper holes 14 are distributed on the surface of the peripheral portion 12 in an array mode, and cross sections of the taper holes 14 intersect at an obtuse angle.

In this embodiment, in order to facilitate the astigmatism entering the peripheral portion 12 to be emitted from the tapered holes 14 and avoid the astigmatism from being refracted to the optical portion 11 to affect the optical imaging, the distribution and the size of the tapered holes 14 are defined as follows, the maximum depth of the tapered holes 14 is defined to be between 0.5mm and 1mm, and the distance between two adjacent tapered holes 14 is defined to be between 2mm and 4mm, so as to ensure the arrangement density of the tapered holes 14. The tapered hole 14 is located in the mounting area and can be used as a snap groove during mounting.

In the present embodiment, for cutting the optical lens, the peripheral portion 12 is defined as follows: the surface of the peripheral part 12 is an inclined plane, and the thickness of the inclined plane is gradually reduced from inside to outside; the included angle between the inclined plane and the horizontal plane is 1-5 degrees. The outer edge of the peripheral portion 12 is provided with a cut surface 15.

In the embodiment, the light-shading agent layer is additionally arranged on the connecting surface to prevent external light from directly entering the optical part from the connecting surface, and the obtuse-angle taper holes are distributed on the peripheral part in an array manner, so that the light scattered in the peripheral part can be scattered to the outside of the optical lens after contacting with the taper holes, and the influence of astigmatism on the imaging of the central optical part is avoided.
