Title
(EN) Optical lens
(ZH) 光学镜头
Abstract
(EN)
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.
