Problems solved by technology

[0003] Traditional optical photography systems mounted on portable electronic products are usually composed of multiple lenses. However, due to the prevalence of high-standard mobile devices such as smart phones, users have higher requirements for the pixels and imaging quality of optical photography systems. The rapid increase, and the size of the photosensitive element is also increasing, so the traditional optical system can no longer meet the current trend

Abstract

The present invention discloses an optical lens. The optical lens has an optical axis; the optical lens comprises a first lens having negative refractive power, a second lens having positive refractive power, a third lens having positive refractive power, a fourth lens having negative refractive power, a fifth lens having positive refractive power, and a sixth lens having negative refractive power which are distributed sequentially from the object side to the image side of the optical lens; the image side surface of the sixth lens has a point of inflexion; a distance from the point of inflexion to the optical axis is h13; the radius of the sixth lens is H13; and h13 and H13 satisfy a relational expression that |h13 / H13|<=0.55.

Description

technical field [0001] The invention relates to an optical lens, and in particular to an optical lens with small volume and good imaging quality. Background technique [0002] In recent years, due to the increasing demand for real-time photography and dynamic photography, as well as the continuous advancement of smart phones and tablet computers, various mobile devices have higher requirements for optical image quality. Moreover, due to the thinner and lighter design of mobile devices, people's demand for optical systems is also increasing. While pursuing miniaturization, higher requirements are gradually put forward for the quality of the captured images. [0003] Traditional optical photography systems mounted on portable electronic products are usually composed of multiple lenses. However, due to the prevalence of high-standard mobile devices such as smart phones, users have higher requirements for the pixels and imaging quality of optical photography systems. The rapid ...
