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：‑10≤f1/f≤‑3.1；1≤f6/f7≤10；1.7≤n6≤2.2；1.7≤n7≤2.2；2≤(R1+R2)/(R1‑R2)≤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 an imaging optical lens. The imaging optical lens sequentially comprises a first lens, a second lens, a third lens, a fourth lens, afifth lens, a sixth lens and a seventh lens from the object side to the image side. The imaging optical lens satisfies the following relational expression: -10 <= f1/f <= -3.1; 1<=f6/f7<=10; 1.7<=n6<=2.2; 1.7<=n7<=2.2; 2<=(R1+R2)/(R1-R2)<=10. The imaging optical lens is high in imaging performance and low in TTL.
