在示例性实施方式中，本申请的光学成像镜头可满足条件式1.2＜ET7/CT7＜1.7，其中，ET7为第七透镜的边缘厚度，CT7为第七透镜在光轴上的中心厚度。更具体地，ET7和CT7进一步可满足1.26≤ET7/CT7≤1.63。满足条件式1.2＜ET7/CT7＜1.7，可有效控制光线偏折，降低光学***的后端尺寸，同时控制第七透镜的厚薄比较小还有利于透镜的成形，避免熔接痕，并可减小成形过程中所产生的应力问题。
在示例性实施方式中，本申请的光学成像镜头可满足条件式2＜(CT3+CT6)/TTL×10＜2.4，其中，CT3为第三透镜在光轴上的中心厚度，CT6为第六透镜在光轴上的中心厚度，TTL为第一透镜的物侧面至光学成像镜头的成像面在光轴上的距离。更具体地，CT3、CT6和TTL进一步可满足2.13≤(CT3+CT6)/TTL×10≤2.20。满足条件式2＜(CT3+CT6)/TTL×10＜2.4，可均衡光学***前后端尺寸的分配，使各个透镜拥有较合理的中心厚度，防止透镜成形后发生破裂，同时还可使***具有较好的场曲矫正能力。
在示例性实施方式中，上述光学成像镜头还可包括光阑，以提升镜头的成像质量。可选地，光阑可设置在物侧与第一透镜之间。
可选地，上述光学成像镜头还可包括用于校正色彩偏差的滤光片和/或用于保护位于成像面上的感光元件的保护玻璃。
根据本申请的上述实施方式的光学成像镜头可采用多片镜片，例如上文所述的七片。通过合理分配各透镜的光焦度、面型、各透镜的中心厚度以及各透镜之间的轴上间距等，可有效地缩小镜头的体积、降低镜头的敏感度并提高镜头的可加工性，使得光学成像镜头更有利于生产加工并且可适用于便携式电子产品。通过上述配置的光学成像镜头还可具有大像面、大光圈、高成像质量等有益效果。
在本申请的实施方式中，各透镜的镜面中的至少一个为非球面镜面，即，第一透镜、第二透镜、第三透镜、第四透镜、第五透镜、第六透镜和第七透镜中的每个透镜的物侧面和像侧面中的至少一个为非球面镜面。非球面透镜的特点是：从透镜中心到透镜周边，曲率是连续变化的。与从透镜中心到透镜周边具有恒定曲率的球面透镜不同，非球面透镜具有更佳的曲率半径特性，具有改善歪曲像差及改善像散像差的优点。采用非球面透镜后，能够尽可能地消除在成像的时候出现的像差，从而改善成像质量。可选地，第一透镜、第二透镜、第三透镜、第四透镜、第五透镜、第六透镜和第七透镜中的每个透镜的物侧面和像侧面均为非球面镜面。
然而，本领域的技术人员应当理解，在未背离本申请要求保护的技术方案的情况下，可改变构成光学成像镜头的透镜数量，来获得本说明书中描述的各个结果和优点。例如，虽然在实施方式中以七个透镜为例进行了描述，但是该光学成像镜头不限于包括七个透镜。如果需要，该光学成像镜头还可包括其他数量的透镜。
下面参照附图进一步描述可适用于上述实施方式的光学成像镜头的具体实施例。
