Embodiment Construction

[0041] The following combination Figure 1 ~ Figure 4 The specific implementation manners of the present invention will be further elaborated.

[0042] A high-pixel wide-angle lens, which is sequentially provided with from the object side to the image side: the first lens 1, the object side is convex, and the image side is concave; the second lens 2, the object side is convex, and the image side is concave; Lens 3, its object side and image side are both convex; stop 4; fourth lens 5, its object side and image side are both convex; fifth lens 6, its object side and image side are both concave; sixth lens 7. Both the object side and the image side are convex. The combination of concave and convex structures adopted by each lens in this solution can achieve better aberration correction performance through rational distribution of optical power, thereby improving imaging clarity.

[0043] Optionally, a filter 8 may also be provided between the sixth lens 7 and the photosensitiv...

Abstract

The invention relates to the technical field of optical lenses, and in particular relates to a high-pixel wide-angle lens. The high-pixel wide-angle lens is provided with a first lens 1, a second lens2, a third lens 3, a diaphragm 4, a fourth lens 5, a fifth lens 6 and a sixth lens 7 from the object side to the image side in sequence. The object side of the first lens 1 is a convex side, and theimage side is a concave side. The object side of the second lens 2 is a convex side, and the image side is a concave side. The object side and the image side of the third lens 3 are convex sides. Theobject side and the image side of the fourth lens 5 are convex sides. The object side and the image side of the fifth lens 6 are concave sides. The object side and the image side of the sixth lens 7 are convex sides. According to the invention, through concave and convex combination structure adopted by the lenses and reasonable focal power distributing, aberration correction can be realized, andthe imaging clarity is improved.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a high-pixel wide-angle lens. Background technique [0002] Wide-angle lenses are widely used in vehicle, monitoring and other fields because of their wide viewing angles and the ability to capture large areas of scenery within a relatively short shooting distance. However, most of the current wide-angle lenses have low pixels, only at the level of 1 million or less, the production cost is high, and the finished product is not light enough, and the relative illuminance of the wide-angle lenses on the market is generally low, and the shooting picture is not uniform, and often Purple fringing occurs. Contents of the invention [0003] Based on this, it is necessary to provide a high-pixel wide-angle lens for the current wide-angle lens with low pixels, high production cost, light-weight finished product, generally low relative illuminance, and frequent purple fringing. ...
