[0003] At present, the conventionally used megapixel vehicle-mounted lenses are mostly 6 lenses, such as the optical lens disclosed in Chinese patent application CN105353499A, which basically meets the requirements of vehicle-mounted lenses, but it is still difficult to meet the recent increasingly higher resolution in terms of resolution. like request
[0004] Although the resolution can be improved by adding lenses, it will also increase the volume and weight, which is difficult to meet the market development trend and will increase the cost

Abstract
The invention discloses an optical camera lens, which comprises, sequentially from an object side to an image side along an optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens, wherein the first lens has positive focal power, the object side surface is a convex surface and the image side surface is a concave surface; the second lenshas positive focal power, the object side surface is a convex surface and the image side surface is a concave surface; the third lens has negative focal power, and both the object side surface and the image side surface are concave surfaces; the fourth lens has positive focal power and the image side surface is a convex surface; the seventh lens has focal power, the object side surface is a concave surface and the image side surface is a convex surface; and the fifth lens can be glued to the sixth lens. According to the optical camera lens disclosed in the invention, effects of miniaturization and high resolution can be achieved.
Description
technical field [0001] The present application relates to an optical lens, and more particularly, the present application relates to an optical lens including seven lenses. Background technique [0002] With the development of technology, the requirements for optical lenses are getting higher and higher, especially the requirements for high resolution and miniaturization of lenses are becoming more and more prominent, especially for vehicle-mounted lenses, which are gradually upgraded from the original megapixels to 2M and 4M. [0003] At present, the conventionally used megapixel vehicle-mounted lenses are mostly 6 lenses, such as the optical lens disclosed in Chinese patent application CN105353499A, which basically meets the requirements of vehicle-mounted lenses, but it is still difficult to meet the recent increasingly higher resolution in terms of resolution. like request. [0004] Although the resolution can be improved by adding lenses, it will also increase the volu...
