Abstract

The invention discloses an optical camera lens, which sequentially comprises a first lens, a second lens, a third lens, a fourth lens and a fifth lens from an object side to an image side along an optical axis, wherein an object side surface and an image side surface of the first lens are both concave surfaces, and at least one surface is an aspheric surface; The second lens element with positiverefractive power has a convex image-side surface, and at least one surface is an aspheric surface; the third lens element has negative refractive power, a convex object-side surface and a concave image-side surface, and at least one surface is an aspheric surface; the fourth lens has negative focal power, and an object side surface and an image side surface are both concave surfaces; the fifth lens element has a convex image-side surface and at least one surface is an aspheric surface; and a sixth lens element with negative refractive power has an image-side concave surface and at least one surface is an aspheric surface. By reasonably distributing the focal power and the surface type of each lens, the center thickness of each lens and the on-axis distance between the lenses, the optical camera lens has the advantages of ultra-thinness, miniaturization, wide angle, low sensitivity and high imaging quality.

Description

technical field [0001] The invention relates to the field of optical lenses, in particular to a wide-angle and high-resolution lens. Background technique [0002] With the continuous development of portable electronic products such as smartphones, lens shooting requires a wider field of view. This requires the role of wide-angle lenses, which have a shorter focal length than standard lenses but have a wider viewing angle. As technology develops, lenses need to meet miniaturization requirements while having wide-angle characteristics. Contents of the invention [0003] The invention is suitable for portable electronic products and can solve the disadvantages of the prior art. [0004] The technical scheme adopted in the present invention is: [0005] A wide-angle high-resolution lens, the lens sequentially includes from the object side to the image side along the optical axis: a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens, wherei...
