需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
以下结合具体实施例进一步描述本申请。
根据本申请示例性实施方式的光学成像镜头具有例如两个透镜组，即第一透镜组和第二透镜组。这两个透镜组沿着光轴从物侧至像侧依序排列。
在示例性实施方式中，第一透镜组可包括第一透镜和第二透镜；第二透镜组可包括至少一个物侧面和像侧面均为非球面的光学元件和至少一个具有光焦度的透镜。其中，第一透镜可具有正光焦度；第二透镜可具有负光焦度；以及光学元件不具有光焦度；通过合理的配置，在保证整个系统光焦度以及各透镜光焦度基本不变的情况下，利用双面的非球面良好的矫正周边视场像差，不仅可有效地平衡控制系统的低阶像差，使得光学成像镜头获得较优的成像品质，而且可有利于增大光圈，同时保证镜头的小型化。
在示例性实施方式中，第二透镜组可包括一个不具有光焦度的光学元件和三个具有光焦度的透镜，其中，三个具有光焦度的透镜中的最靠近光学成像镜头的成像面的一个透镜可具有负光焦度。
在另一示例性实施方式中，第二透镜组可包括两个不具有光焦度的光学元件和两个具有光焦度的透镜，其中，两个具有光焦度的透镜中的最靠近光学成像镜头的成像面的一个透镜可具有负光焦度。
在示例性实施方式中，第一透镜的有效焦距f1与第一透镜和第二透镜的组合焦距f12之间可满足：f1/f12>0.65，更具体地，可进一步满足f1/f12≥0.68。通过合理配置第一透镜和第二透镜的组合焦距，可有助于缩短光学成像镜头系统的场曲，减小轴上球差。
在示例性实施方式中，第一透镜物侧面至光学成像镜头的成像面在光轴上的距离TTL与光学成像镜头成像面上有效像素区域对角线长的一半ImgH之间可满足：TTL/ImgH≤1.5，更具体地，可进一步满足TTL/ImgH≤1.47。通过这样的配置，可减小边缘视场的像差，有效地 压缩了光学成像镜头系统的尺寸，保证镜头小型化需求。
在示例性实施方式中，光学成像镜头成像面上有效像素区域对角线长的一半ImgH与光学成像镜头的有效焦距f之间可满足：ImgH/f≥0.85，更具体地，可进一步满足ImgH/f≥0.86。通过合理选择ImgH和f的比值，能够提升系统镜头视场角，保证系统镜头的大视场角特性。
在示例性实施方式中，第一透镜和第二透镜的组合焦距f12与最靠近成像面的透镜的有效焦度fL之间可满足：-3≤f12/fL≤-1，更具体地，可进一步满足-2.94≤f12/fL≤-1.14。通过f12与fL光焦度的合理配置，可基本确定系统整体光焦度，同时改善轴向色差、高级象散、畸变等像差。
在示例性实施方式中，第二透镜物侧面的曲率半径R3与第二透镜像侧面的曲率半径R4之间可满足：|R3-R4|/|R3+R4|≤3，更具体地，可进一步满足|R3-R4|/|R3+R4|≤2.64。在镜头光圈增大时，可通过改变曲率半径的配置，有效地改善高级球差。
在示例性实施方式中，第一透镜物侧面的曲率半径R1与第二透镜像侧面的曲率半径R4之间可满足：0≤R1/R4≤1，更具体地，可进一步满足0.14≤R1/R4≤0.57。通过第一透镜物侧面曲率半径与第二透镜像侧面曲率半径的相互补偿，可有效改善球差，同时有助于确定第一透镜物侧面以及第二透镜像侧面的形状，保证加工性。
在示例性实施方式中，光学成像镜头的有效焦距f与光学成像镜头的入瞳直径EPD之间可满足：f/EPD≤2.0，更具体地，可进一步满足f/EPD≤1.99。通过这样的配置，可有利于加大通光量，使系统具有大光圈优势，增强暗环境下的成像效果。
在示例性实施方式中，满足0≤∑CT/∑AT≤3，，更具体地，可进一步满足0.57≤∑CT/∑AT≤2.85，其中，∑CT为第一透镜至最靠近成像面的透镜中各个具有光焦度的透镜的中心厚度的总和，∑AT为第一透镜至最靠近成像面的透镜中任意相邻两具有光焦度的透镜之间在光轴上的空气间隔的总和。通过这样的配置，可具有良好的成像品质，同时保证镜头小型化。
在示例性实施方式中，最靠近成像面的透镜物侧面的曲率半径RL1与最靠近成像面透镜像侧面的曲率半径RL2之间可满足：|RL1+RL2|/|RL1-RL2|≤3，更具体地，可进一步满足|RL1+RL2|/|RL1-RL2|≤2.3。通过这样的配置，可有助于匹配芯片的主光线入射角度，从而提升相对亮度，同时矫正象散。
在示例性实施方式中，第一透镜的阿贝数V1与无光焦度的光学元件的阿贝数Vne之间可满足：|Vne-V1|≤40，更具体地，可进一步满足|Vne-V1|≤33.74。通过不同材料之间阿贝数相互作用，可矫正像差。
在示例性实施方式中，第一透镜至最靠近成像面的透镜中任意相邻两具有光焦度的透镜之间在光轴上的空气间隔的总和∑AT与光学成像镜头的有效焦距f之间可满足：0≤∑AT/f≤1.1，更具体地，可进一步满足0.20≤∑AT/f≤1.05。通过这样的配置，可保证镜头的小型化，通过轴上间距的改变，可使光线偏折趋于缓和，减小相应像差的产生，降低敏感性。
在示例性实施方式中，光学成像镜头还可设置有用于限制光束的光圈STO，调节进光量，提高成像品质。根据本申请的上述实施方式的光学成像镜头可采用多个镜片，例如上文所述的六个。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，可有效扩大光学成像镜头的孔径、降低系统敏感度、保证镜头的小型化并提高成像质量，从而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。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。非球面透镜的特点是：曲率从透镜中心到周边是连续变化的。与从透镜中心到周边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，能够使得视野变得更大而真实。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。另外，非球面透镜的使用还可有效地减少光学系统中的透镜个数。
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六个光学元件为例进行了描述，但是该光学成像镜头不限于包括六个光学元件。如果需要，该光学成像镜头还可包括其它数量的透镜。
