Embodiment approach

[0018] like figure 1 As shown, the present invention discloses a wide-angle high-resolution optical lens, which comprises in sequence from the object side to the image side: a first lens 1 of a meniscus negative lens, a second lens 2 of a meniscus negative lens, A third lens 3 of a biconvex positive lens, a diaphragm 7, a cemented lens group composed of a fourth lens 4 and a fifth lens 5, and a sixth lens 6 of a biconvex positive lens;

[0019] Wherein the first lens 1 is a meniscus negative lens, its object-side surface 11 is a convex surface, and the image-side surface 12 is a concave surface; the radius of curvature R11 of the object-side surface 11 of the first lens 1 is 65 mm to 85 mm, and the image-side surface 12 is The radius of curvature R12 is -3.3 mm ~ -4.0mm.

[0020] The second lens 2 is also a meniscus negative lens, its object side surface 21 is a convex surface, and the image side surface 22 is concave; the radius of curvature R21 of the object side surface 21...

Abstract

The invention discloses a wide-angle and high-resolution small optics lens. The wide-angle and high-resolution small optics lens comprises a first lens of a negative meniscus lens, a second lens of the negative meniscus lens, a third lens of a biconvex positive lens, a diaphragm, a bonding lens set and a sixth lens of the biconvex positive lens in sequence from the object side to the image side, wherein the bonding lens set is composed of a fourth lens and a fifth lens. The wide-angle and high-resolution small optics lens composed of the lenses not only is small in size, but also can correct the system aberration effectively and reduce the sensitivity degree of a lens system so as to obtain the higher resolution power, then the resolution of a lens is larger than the pixel of two millions, the wide-angle and high-resolution small optics lens can be well used on a chip of the pixel of 5 millions, the image definition and uniformity of the surrounding image quality are improved, the defect that a traditional lens is low in performance index is overcome, and the wide angle and the high resolution are achieved.

Description

technical field [0001] The invention relates to an optical lens, in particular to a small wide-angle and high-resolution optical lens used in the fields of network cameras, driving recorders, monitoring and the like. Background technique [0002] Various types of small lenses currently in use have relatively low resolutions and can only be adapted to 300,000-pixel chips. With the continuous emergence of various high-resolution CCDs and CMOS image sensors, image capture has entered the era of high-definition production. In order to cooperate with the chip of the high-definition camera, the lens must increase the corresponding pixel. Especially in applications such as driving recorders and network cameras in recent years, the requirements for high-definition lenses are more obvious. Contents of the invention [0003] The object of the present invention is to provide a kind of wide-angle and high-resolution optical small lens that cooperates with the application of driving ...
