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；1.7≤n4≤2.2；1≤f6/f7≤10；1.7≤(R1+R2)/(R1‑R2)≤10；0.01≤d7/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, which relates to the field of the optical lens, discloses an optical shooting lens comprising a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and aseventh lens that are arranged successively from an object side to an image side. The following relational expressions are met: f1/f is larger than or equal to -10 and is less than or equal to -3.1;the n4 is larger than or equal to 1.7 and is less than or equal to 2.2; f6/f7 is larger than or equal to 1 and is less than or equal to 10; (R1+R2)/(R1 R2) is larger than or equal to 1.7 and is less than or equal to 10; and d7/TTL is larger than or equal to 0.01 and is less than or equal to 0.2. According to the optical shooting lens, the high imaging performance is realized; and the low TTL is obtained.
