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；所述第一透镜为塑料材质，所述第二透镜为塑料材质，所述第三透镜为塑料材质，所述第四透镜为玻璃材质，所述第五透镜为塑料材质，所述第六透镜为塑料材质，所述第七透镜为玻璃材质；且满足下列关系式：‑3≤f1/f≤‑1,1.7≤n4≤2.2,1≤f6/f7≤10；2≤(R1+R2)/(R1‑R2)≤10；1.7≤n7≤2.2。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 seventh lenses; the first to third lenses are made of a plastic material; the fourth lens is made of a glass material; the fifth and sixth lenses are made of a plastic material; the 7th lens is made of aglass material; the lenses comply with the following relations: 3<=f1/f<= 1, 1.7<=n4<=2.2, 1<=f6/f7<=10; 2<=(R1+R2)/(R1 R2)<=10; 1.7<=n7<=2.2. The camera shooting optical lenses can obtain the high imaging performance and the low TTL in the same time.
