本发明的实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明的各实施方式进行详细的阐述。然而，本领域的普通技术人员可以理解，在本发明各实施方式中，为了使读者更好地理解本发明而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施方式的种种变化和修改，也可以实现本发明所要求保护的技术方案。
(第一实施方式)
参考附图，本发明提供了一种摄像光学镜头10。图1所示为本发明第一实施方式的摄像光学镜头10，该摄像光学镜头10包括六个透镜。具体的，所述摄像光学镜头10，由物侧至像侧依序包括：光圈S1、第一透镜L1、第 二透镜L2、第三透镜L3、第四透镜L4、第五透镜L5以及第六透镜L6。本实施方式中，优选的，在第六透镜L6和像面Si之间设置有玻璃平板GF等光学元件，其中玻璃平板GF可以是玻璃盖板，也可以是光学过滤片(filter)，当然在其他可实施方式中，玻璃平板GF还可以设置在其他位置。
本实施方式中，第一透镜L1具有正屈折力，其物侧面向外凸出为凸面，其像侧面为凹面；第二透镜L2具有负屈折力，其物侧面为凸面，其像侧面为凹面；第三透镜L3具有正屈折力，其物侧面为凹面，其像侧面为凸面；第四透镜L4具有负屈折力，其物侧面为凹面，其像侧面为凸面；第五透镜L5具有正屈折力，其物侧面为凸面，其像侧面为凸面；第六透镜L6和具有负屈折力，其物侧面为凹面，其像侧面为凹面。
在此，定义整体摄像光学镜头10的焦距为f，所述第二透镜的焦距为f2，所述第四透镜的焦距为f4，所述第二透镜物侧面的曲率半径为R3，所述第二透镜像侧面的曲率半径为R4，所述第四透镜物侧面的曲率半径为R7，所述第四透镜像侧面的曲率半径为R8，满足下列关系式：
-9.00≤f2/f≤-6.00，   (1)
9.00≤f2/f4≤13.00，   (2)
11.00≤(R3+R4)/(R3-R4)≤20.00，   (3)
0.02≤R7/R8≤0.30。   (4)
其中，条件式(1)规定了第二透镜L2的焦距与整体摄像光学镜头10焦距的比值，在此条件范围内时，能有效地平衡第一透镜产生的球差以及***的场曲。
条件式(2)规定了第二透镜L2的焦距和第四透镜L4焦距的比值。通过焦距的合理分配，使得***具有较佳的成像品质和较低的敏感性。
条件式(3)规定了第二透镜L2的形状，在此条件范围内时，有利于补 正轴上色像差。
条件式(4)规定了第四透镜L4的形状，在此条件范围外时，随着超薄广角化的发展，很难补正轴外画角的像差等问题。
本实施方式中，通过上述透镜的配置方式，使摄像光学镜头在具有良好光学性能的同时，满足广角化和超薄化的设计要求。
优选的，本发明实施方式中，所述第三透镜的轴上厚度为d5，所述摄像光学镜头的光学总长为TTL，满足下列关系式：
0.10≤d5/TTL≤0.20。   (5)
条件式(5)规定了第三透镜L3的轴上厚度d5与镜头光学总长TTL的比值，在此条件范围内时，有利于在超薄化的情况下提高***像质。
优选的，本实施方式中，所述第一透镜的轴上厚度为d1，所述第一透镜的像侧面到所述第二透镜的物侧面的轴上距离为d2，满足下列关系式：
7.00≤d1/d2≤10.00。   (6)
条件式(6)规定了第一透镜L1的轴上厚度与第一透镜L1的像侧面到第二透镜L2的物侧面的轴上距离的比值，在条件式范围内有助于压缩光学***总长，实现超薄化效果。
优选的，本实施方式中，所述第六透镜物侧面的曲率半径为R11，所述第六透镜像侧面的曲率半径为R12，满足下列关系式：
0.20≤(R11+R12)/(R11-R12)≤0.80。   (7)
条件式(7)规定了第六透镜L6的形状，在此条件范围内时，有利于补正轴外画角的像差。
此外，透镜的表面可以设置为非球面，非球面可以容易制作成球面以外的形状，获得较多的控制变数，用以消减像差，进而缩减透镜使用的数目，因此可以有效降低本发明摄像光学镜头的总长度。本发明实施例中，各个透 镜的物侧面和像侧面均为非球面。
值得一提的是，由于构成本实施方式的摄像光学透镜10的第一透镜L1、第二透镜L2、第三透镜L3、第四透镜L4、第五透镜L5以及第六透镜L6具有如前所述的结构和参数关系，因此，摄像光学镜头10能够合理分配各透镜的光焦度、面型以及各透镜的轴上厚度等，并因此校正了各类像差，本发明中摄像光学镜头10的光学总长TTL，摄像光学镜头10的像高IH，满足下列关系式：TTL/IH≤1.47；摄像光学镜头10的视场角FOV，满足以下关系式：FOV≥78度。实现了在具有良好光学成像性能的同时，满足广角化和超薄化的设计要求。
优选的，所述透镜的物侧面和/或像侧面上还可以设置有反曲点和/或驻点，以满足高品质的成像需求，具体的可实施方案，参下所述。
以下示出了本发明第一实施方式中摄像光学镜头10的设计数据。需要说明的是，本实施方式中，距离、半径和中心厚度的单位为毫米(mm)。
