Title
(EN) Camera shooting optical lens
(ZH) 摄像光学镜头
Abstract
(EN) The invention relates to the field of optical lenses, and discloses a camera shooting optical lens, which comprises seven lenses, namely a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens in sequence from an object side to an image side. The first lens has negative refractive power, the third lens has positive refractive power, the fourth lens has negative refractive power, the sixth lens has positive refractive power, the seventh lens has negative refractive power, and at least one of the first lens to the seventh lens comprises a free-formsurface. The camera shooting optical lens provided by the invention has good optical performance and meets the design requirements of ultrathin and wide angle.
(ZH) 本发明涉及光学镜头领域,公开了一种摄像光学镜头,该摄像光学镜头共包括七片透镜,七片所述透镜自物侧至像侧依序为:第一透镜,第二透镜,第三透镜,第四透镜,第五透镜,第六透镜,以及第七透镜;第一透镜具有负屈折力,第三透镜具有正屈折力,第四透镜具有负屈折力,第六透镜具有正屈折力,第七透镜具有负屈折力,第一透镜至第七透镜中的至少一个含自由曲面。本发明提供的摄像光学镜头具有良好光学性能的同时,满足超薄化、广角化的设计要求。
