Abstract

The invention provides a camera shooting optical lens. The camera shooting optical lens includes from the side of an object to the side of an image: a first lens having a positive refractive power, asecond lens having a negative refractive power, a third lens having a positive refractive power, a fourth lens having a positive refractive power, and a fifth lens having a negative refractive power,and the following relationships that -0.50<=f1 / f2<=-0.35, 20.00<=f3 / f<=30.00, -3.10<=(f2+f5) / f<=-2.40, -1.80<=(R1+R2) / (R1-R2)<=-1.60, 4.50<=(R5+R6) / (R5-R6)<=6.00, and 1.10<=d8 / d9<=1.30 are satisfied.While the camera shooting optical lens has good optical performance, the wide-angle and ultra-thin design requirements are also met.

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 mainstrea...
