Abstract

The invention discloses a pick-up lens. The pick-up lens sequentially comprises a first lens withpositive focal power; a second lens with positive focal power; a third lens with focal power; a fourth lens with focal power; a fifth lens with focal power; a sixth lens with negative focal power; a seventh lens with focal power; an eighth lens with focal power; a ninth lens with negative focal power; and a tenth lens has focal power which are arranged from an object side to an image side along an optical axis,. The total effective focal length f of the pick-up lens and the entrance pupil diameter EPD of the pick-up lens meet the condition that f / EPD is less than 1.7.

Description

technical field [0001] The present application relates to the field of optical elements, in particular, to a camera lens. Background technique [0002] With the continuous development of portable electronic products such as smart phones, people have put forward higher requirements for the performance of camera lenses of portable electronic products such as smart phones. Due to the limitations of the number of lenses, the size of the aperture, and its own structure, most of the camera lenses currently on the market cannot meet the imaging requirements in conditions such as insufficient light (such as cloudy and rainy days, dusk, etc.) and hand shake. Because the multi-chip camera lens provides more design freedom, it will provide greater possibilities for improving the performance of portable electronic products such as smartphones. Contents of the invention [0003] One aspect of the present application provides such a camera lens, which includes in sequence from the obje...
