Camera Optical Lens

Abstract

The invention relates to the field of optical lenses, and discloses a photographic optical lens, which sequentially includes a first lens, a second lens, a third lens, a fourth lens, and a fifth lens from the object side to the image side; Satisfy the following relations: 0.30≤f1 / f≤0.50; -0.80≤f2 / f≤-0.40; 40.00≤d1 / d2≤50.00; 1.80≤d4 / d5≤2.24. The camera optical lens can obtain high imaging performance and at the same time meet the design requirements of large aperture, wide-angle, and ultra-thin.

Description

technical field [0001] The invention relates to the field of optical lenses, in particular to an imaging optical lens suitable for portable terminal devices such as smart phones and digital cameras, and imaging devices such as monitors and PC lenses. Background technique [0002] In recent years, with the rise of smart phones, the demand for miniaturized photographic lenses has been increasing, and the photosensitive devices of general photographic lenses are nothing more than photocoupled devices (Charge Coupled Device, CCD) or complementary metal oxide semiconductor devices (Complementary Metal -Oxide Semiconductor Sensor, CMOS Sensor), and due to the improvement of semiconductor manufacturing process technology, the pixel size of photosensitive devices has been reduced, and today's electronic products are developing with good functions and thin, light and small appearance. Therefore, it has Miniaturized camera lenses with good imaging quality have become the mainstream in...

AI Technical Summary

Problems solved by technology

However, the focal power distribution of the existing structure, the thickness and shape of the lens are not set sufficiently, resulting in the problem of insufficient telephoto lens, so there is an urgent need for a telephoto camera lens with excellent optical characteristics, ultra-thin and fully compensated chromatic aberration
