Problems solved by technology

However, with the development of technology and the increase of diversified needs of users, as the pixel area of ​​the photosensitive device continues to shrink, and the system’s requirements for imaging quality continue to increase, the six-element lens structure gradually appears in the lens design. Common Although the six-element lens already has good optical performance, its focal power, lens spacing and lens shape settings are still unreasonable, resulting in a lens structure that cannot meet wide-angle, Ultra-thin design requirements

Abstract

The invention provides a camera shooting optical lens. The camera shooting optical lens comprises six lenses which are sequentially a first lens with negative refractive power, a second lens with positive refractive power, a third lens with positive refractive power, a fourth lens with negative refractive power, a fifth lens with positive refractive power and a sixth lens with negative refractivepower from the object side to the image side, wherein the Abbe number of the first lens is v1, the Abbe number of the third lens is v3, the on-axis distance from the image side surface of the fifth lens to the object side surface of the sixth lens is d10, the on-axis thickness of the sixth lens is d11, and the following relational expressions are satisfied, 60.00 < / = v1 < / = 90.00, 60.00 < / = v3 < / =90.00, 1.00 < / = d10 / d11 < / = 5.00. The camera shooting optical lens has good optical performance and meets design requirements of ultra-wide angle and ultra-thinness.

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...
