Optical lens and electronic equipment with same

The invention provides an optical lens and electronic equipment with the optical lens, and the optical lens comprises a first lens which has positive focal power, and the first side surface of the first lens is a convex surface; the second lens has negative focal power, the first side surface of the second lens is a concave surface, and the second side surface of the second lens is a convex surface; the third lens has positive focal power, and the first side face of the third lens is a convex face. According to the invention, at least one of the problems of large number of lenses, large rear end aperture, short rear focus and large chief ray angle of the optical lens in the prior art is solved. 本发明提供了一种光学镜头及具有其的电子设备，光学镜头包括：第一透镜，第一透镜具有正光焦度，第一透镜的第一侧面为凸面；第二透镜，第二透镜具有负光焦度，第二透镜的第一侧面为凹面，第二透镜的第二侧面为凸面；第三透镜，第三透镜具有正光焦度，第三透镜的第一侧面为凸面。本发明解决了现有技术中光学镜头透镜数量多、后端口径大、后焦短、主光线角较大中的至少一种问题。
