Abstract

The invention discloses a pick-up lens. The pick-up lens sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens and a tenth lens from an object side to an image side along an optical axis, wherein the seventh lens has positive focal power; the eighth lens has positive focal power; the object side surface of the ninth lens is a concave surface, and the image side surface is a convex surface; the half ImgH of the diagonal length of an effective pixel area on the imaging surface of the pick-up lens meets ImgH> 6 mm.

Description

technical field [0001] The present application relates to the field of optical elements, and more specifically, to a camera lens. Background technique [0002] With the continuous development of portable electronic products such as smart phones, people continue to put forward higher requirements for the performance of mobile phone camera lenses. The multi-element camera lens provides more possibilities for improving the shooting performance of mobile phones because it provides more design freedom. In addition, the aperture number of a conventional lens is usually above 2.0, but for conditions such as rainy days, dusk and other conditions such as insufficient light and hand shake, an aperture number above 2.0 can no longer meet higher-level imaging requirements. [0003] Therefore, in order to better adapt to the market demand and the market trend of ultra-thin mobile phones, it is expected to provide a camera lens with large aperture and ultra-thin characteristics that is a...
