摄像光学镜头
摘要：
本发明涉及光学镜头领域，公开了一种摄像光学镜头，该摄像光学镜头自物侧至像侧依序包含：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；且满足下列关系式：1≤f1/f≤1.5,1.7≤n2≤2.2,1.7≤n6≤2.2,‑2≤f3/f4≤2；0.5≤(R13+R14)/(R13‑R14)≤10。该摄像光学镜头能获得高成像性能的同时，获得低TTL。
摘要（英）：

The invention relates to the field of optical lenses, and discloses a camera shooting optical lens. The camera shooting optical lens sequentially comprises a first lens, a second lens, a third lens, afourth lens, a fifth lens, a sixth lens and a seventh lens from an object side to an image side. The camera shooting optical lens meets the following relations: f1/f is greater than or equal to 1 andless than or equal to 1.5, n2 is greater than or equal to 1.7 and less than or equal to 2.2, n6 is greater than or equal to 1.7 and less than or equal to 2.2, f3/f4 is greater than or equal to -2 andless than or equal to 2, and (R13+R14)/(R13-R14) is greater than or equal to 0.5 and less than or equal to 10. The camera shooting optical lens can acquire low TTL while achieving high imaging performance.
