Abstract

The present invention provides a photographic optical lens, the photographic optical lens comprises in sequence from the object side to the image side: a first lens with positive refractive power, a second lens with negative refractive power, a third lens with positive refractive power, The fourth lens with negative refractive power, the fifth lens with negative refractive power, and the sixth lens with refractive power; the focal length of the imaging optical lens is f, the focal length of the first lens is f1, and the focal length of the third lens is f3 , the radius of curvature of the object side of the fourth lens is R7, and the radius of curvature of the image side of the fourth lens is R8 to satisfy the relational formula: 0.60≤f1 / f≤0.80; 2.00≤f3 / f≤5.00; 2.00≤(R7+R8) / (R7‑R8)≤4.50. The camera optical lens can meet the design requirements of large aperture and long focal length while having good optical performance.

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] With the continuous development of science and technology, the functions of electronic equipment are constantly improving. In addition to traditional digital cameras and independent cameras, monitors, etc., portable electronic equipment such as tablet computers and mobile phones are also equipped with camera optical lenses, and require electronic equipment such as mobile phones. The lens in the device meets the requirements of thinness and lightness while having good imaging quality. [0003] At present, most of the camera lenses mounted on mobile phones and other electronic devices on the market adopt a multi-chip structure, and most of them are four-chip, five-chip, and six-chip lenses. Howeve...
