Abstract

An optical lens and an electronic device using the optical lens, the electronic device has at least one optical lens. The optical lens sequentially includes 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 the object side to the image side . The second lens and the third lens have negative diopter, and the fourth lens, the sixth lens and the eighth lens have positive diopter. The first lens is a plastic lens with a convex surface on the object side and / or a concave surface on the image side, and the sixth lens and the seventh lens form a composite lens. The above-mentioned optical lens and electronic device can maintain a certain resolution in different environments under the premise that the viewing angle is increased or substantially unchanged.

Description

technical field [0001] The invention relates to an optical lens and an electronic device using the optical lens, and in particular to an optical lens with a wider viewing angle and capable of capturing images in different media and an electronic device using the optical lens. Background technique [0002] In recent years, due to the rise of random photography activities in sports, the demand for thin, light and short optical lenses has greatly increased, and it has also brought about a trend of small high-quality image capture devices. This type of device is mainly used in real-time outdoor activities. For image shooting, the lens suitable for this type of device needs to have the characteristics of small overall length and ultra-wide angle. [0003] The image capturing devices generally used in normal environments have low flexibility to adjust camera parameters according to the environment. For example, the camera quality of the image capture device cannot overcome the pr...
