Abstract

The present invention provides a photographic optical lens, the photographic optical lens comprises: a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens in order from the object side to the image side And the eighth lens; the first lens, the third lens, the fifth lens and the seventh lens have positive refractive power, the second lens, the fourth lens, the sixth lens and the eighth lens have negative refractive power, and the focal length of the imaging optical lens is f, the focal lengths of the first lens, the fourth lens and the fifth lens are f1, f4 and f5 respectively, and satisfy the following relational formula: 0.70≤f1 / f≤1.00; -20.00≤f4 / f≤3.50; 2.30≤f5 / f≤4.50. The camera optical lens can meet the design requirements of large aperture, wide angle and ultra-thin 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. Therefore, miniaturized camera lenses with good imaging quality have become the mainstream in the current market. [0003] In order to obtain better imaging quality, the lenses traditionally mounted on mobile phone ...
