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，以及第六透镜；所述第二透镜具有负屈折力，所述第三透镜具有正屈折力；且满足下列关系式：0.5≤f1/f≤10；1.7≤n3≤2.2；1.7≤n4≤2.2；0.062≤d5/TTL≤0.2。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 optical lens field, and discloses camera shooting optical lenses comprising the following units arranged in order from the object side to the image side: the first to sixth lenses; the second lens has a negative flexion force; the third lens has a positive flexion force; the lenses comply with the following relations: 0.5<=f1/f<=10; 1.7<=n3<=2.2; 1.7<=n4<=2.2; 0.062<=d5/TTL<=0.2. The camera shooting optical lenses can obtain the high imaging performance and the low TTL in the same time.
