Problems solved by technology

[0003] However, when the focal length of the optical imaging lens is increased, the aperture value also increases, causing the overall brightness of the lens to decrease. Therefore, how to increase the effective focal length of the optical imaging lens while maintaining the imaging quality and maintaining the aperture value is the same as the manufacturing yield. Topics that need to be explored in depth

Abstract

The invention provides an optical imaging lens. The optical imaging 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. By means of controlling the concave-convex curved surface arrangement of the surfaces of the five lenses, the optical imaging lens achieves the purposes of increasing the effective focal length, maintaining the aperture value and having good imaging quality.

Description

technical field [0001] The invention relates to the field of optical imaging, in particular to an optical imaging lens. Background technique [0002] The specifications of portable electronic products are changing with each passing day, and its key components - optical imaging lenses are also becoming more diversified. The scope of application is not limited to shooting images and videos, but also needs to be telephoto. The optical zoom function can be achieved by combining the telephoto lens with the wide-angle lens; the longer the effective focal length of the telephoto lens, the higher the magnification of the optical zoom. [0003] However, when the focal length of the optical imaging lens is increased, the aperture value also increases, causing the overall brightness of the lens to decrease. Therefore, how to increase the effective focal length of the optical imaging lens while maintaining the imaging quality and maintaining the aperture value is the same as the manufac...
