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] With the advancement of technology, smart phones have become an indispensable application device in people's daily lives. In particular, the camera function of smart phones plays an increasingly important role in people's daily lives. At the same time, with the development trend of miniaturization of smartphones, users are looking for a thinner and lighter profile while pursuing the imaging performance of the optical imaging lens mounted on the smartphone. [0003] At present, in order to improve the imaging performance of the optical imaging lens in the market, mechanical zooming is often used to satisfy the optical imaging lens with good imaging effect in different shooting scenarios. However, an optical imaging lens with a mechanical zoom function is bulky and difficult to install in a mobile phone, and the ...
