Abstract

The invention discloses a camera shooting optical lens that comprises, in order from an object side to an image side: an optical turning element and a second lens with focal power, wherein the opticalturning element has focal power and is provided with an incident surface, a reflecting surface and an emergent surface; the incident surface and the emergent surface are aspheric mirror surfaces, thereflecting surface is a plane mirror surface; the optical turning element is configured to enable light entering the optical turning element through the incident surface in the Y optical axis direction to be reflected by the reflecting surface and then to be emitted out through the emergent surface in the X optical axis direction, and the Y optical axis direction and the X optical axis directionintersect with each other; the second lens with focal power is provided, wherein the total effective focal length f of the camera shooting optical lens can meet the condition that f is larger than orequal to 20 mm and smaller than or equal to 30 mm.

Description

technical field [0001] The present application relates to a photographic optical lens, more specifically, to a photographic optical lens comprising two lenses. Background technique [0002] With the rapid development of the smartphone industry, mobile phone lenses are developing in the direction of high resolution, large field of view, light weight and versatility. This requires the optical system of the mobile phone lens to have many characteristics such as large aperture, long focal length, wide field of view, compact structure, high image quality and low distortion. Faced with these high requirements, the mobile phone lens system is becoming more and more complex. From the beginning, a mobile phone system required 4 or 5 lenses to the current 7 or 8 lenses. Especially for telephoto lenses, the method of increasing the number of lenses is usually adopted. To take into account the telephoto characteristics and high imaging quality. [0003] However, the addition of system...
