Problems solved by technology

Although the large aperture design can allow the lens to accept more imaging light, it makes the design more difficult; and the high resolution makes the resolution of the lens must be improved, and the large aperture design makes the overall design more difficult.

Abstract

The invention provides an optical imaging lens assembly. The optical imaging lens assembly sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens,a seventh lens and an eighth lens from an object side to an image side. According to the optical imaging lens assembly, the concave-convex curved surface arrangement of the lenses is controlled; underthe condition of maintaining good imaging quality, the system length is shortened, the aperture is increased, and the image height and the resolution are increased.

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 devices, such as mobile phones, cameras, tablet computers, and personal digital assistants (PDA), are changing with each passing day, and their key components - optical imaging lenses are also becoming more diversified. For the main lens of the portable electronic device, not only a larger aperture and a shorter system length are required, but also higher pixels and higher resolution are pursued. The high pixel size implies that the image height of the lens must be increased, and the pixel requirement is increased by using a larger image sensor to receive imaging light. Although the design of large aperture allows the lens to accept more imaging light, it makes the design more difficult; and the high resolution makes the resolution of the lens must be improved, and the design of large ...
