Abstract

The optical imaging lens sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an object side to an image side along an optical axis, the second lens has positive focal power; the third lens has negative focal power; and the fourth lens has focal power. The entrance pupil diameter (EPD) of the optical imaging lens and the total effective focal length f of the optical imaging lens meet the condition that f / EPD is larger than 4.

Description

technical field [0001] The present application relates to the field of optical elements, and in particular, to an optical imaging lens. Background technique [0002] In recent years, with the rapid development of portable electronic products such as smart phones, users have higher and higher requirements for functions such as smart phones, especially for the camera function of mobile phones. Conventional lenses can no longer meet the needs of users. In order to make the optical imaging lens mounted on the smartphone gradually develop in the direction of high definition and high imaging quality, the telephoto lens has been favored by many lens manufacturers. However, the total length of the traditional telephoto lens is relatively long, which will seriously limit the development of the miniaturization of optical imaging lenses, thereby hindering the development of the miniaturization of smartphones. SUMMARY OF THE INVENTION [0003] An aspect of the present application pro...
