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 and a fifth lens from an object side to an image side along an optical axis, the second lens has focal power; the third lens has negative focal power; the fourth lens has focal power; the fifth lens has negative focal power; and the sixth lens has positive focal power. The distance TTL from the object side surface of the first lens to the imaging surface of the camera lens on the optical axis and the maximum field angle FOV of the camera lens meet the condition that TTL / Tan (FOV) is more than or equal to 6mm and less than 8.0 mm; and the Abbe number V1 of the first lens and the Abbe number V2 of the second lens meet the condition that (V1 + V2) / 2 is more than 70 and less than 90.

Description

technical field [0001] The present application relates to the field of optical elements, in particular, to a camera lens. Background technique [0002] As users continue to pursue the thickness of mobile phones and the quality of photos taken, the current camera lenses mounted on mobile phones can no longer meet the needs of users. How to reasonably set the focal power, surface shape, material, and key technical parameters of the camera lens so that the camera lens has higher imaging performance, smaller volume, and more imaging effects has become a problem for many lens manufacturers. One of the main aspects for manufacturers to improve their product competitiveness. Contents of the invention [0003] One aspect of the present application provides such a camera lens, which includes in sequence from the object side to the image side along the optical axis: a first lens with positive refractive power; a second lens with refractive power; The 3rd lens of power; The 4th len...
