以下对本申请的特征、原理和其他方面进行详细描述。
根据本申请示例性实施方式的光学成像镜头包括例如七片具有光焦度的透镜，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。这七片透镜沿着光轴从物侧至像侧依序排列。
第一透镜具有正光焦度或负光焦度，其物侧面可为凸面；第二透镜可具有正光焦度，其物侧面可为凸面；第三透镜可具有负光焦度，其像侧面可为凹面；第四透镜、第五透镜、第六透镜均具有正光焦度或负光焦度；第七透镜具有负光焦度。

光学成像镜头的总有效焦距f与光学成像镜头的入瞳直径EPD之间可满足f/EPD≤1.95，更具体地，f和EPD进一步可满足1.49≤f/EPD≤1.90。光学成像镜头的光圈数Fno(即，镜头的总有效焦距f/镜头的入瞳直径EPD)越小，镜头的通光孔径越大，在同一单位时间内的进光量便越多。光圈数Fno的缩小，可有效地提升像面亮度，使得镜头能够更好地满足例如阴天、黄昏等光线不足时的拍摄需求。将镜头配置成满足条件式f/EPD≤1.95，可在加大通光量的过程中，使镜头具有大光圈优势，增强成像面的照度，从而提升镜头在暗环境下的成像效果。
第四透镜的色散系数V4、第五透镜的色散系数V5与第六透镜的色散系数V6之间可满足(V4+V5+V6)/4≤45，更具体地，V4、V5和V6进一步可满足32.98≤(V4+V5+V6)/4≤33.15。通过对各透镜材料的合理选取，实现矫正镜头色差的目的。

第一透镜的有效焦距f1、第二透镜的有效焦距f2与第三透镜的有效焦距f3之间可满足-1.5＜f3/(f1+f2)＜0，更具体地，f1、f2和f3进一步可满足-1.25≤f3/(f1+f2)≤-0.13。通过对各透镜光焦度的合理分配，可有效地减小高级球差，降低中心视场敏感性，同时还可有效地矫正光学成像系统的色差。
光学成像镜头的总有效焦距f与第四透镜和第五透镜的组合焦距f45之间可满足|f/f45|≤0.5，更具体地，f和f45进一步可满足0.07≤|f/f45|≤0.41。满足条件式|f/f45|≤0.5，有利于减缓光线偏折角度，改善高级象散，降低系统敏感性。
第六透镜可具有正光焦度。光学成像镜头的总有效焦距f与第六透镜的有效焦距f6之间可满足f/f6＞0.6，更具体地，f和f6进一步可满足0.69≤f/f6≤1.48。合理分配第六透镜的光焦度，，有利于提升镜头的成像质量。
第七透镜可具有负光焦度。光学成像镜头的总有效焦距f与第七透镜的有效焦距f7之间可满足-2＜f/f7＜0，更具体地，f和f7进一步可满足-1.81≤f/f7≤-0.72。合理分配第七透镜的光焦度，有利于矫正象散，改善畸变，匹配芯片主光线角度。
第三透镜像侧面的曲率半径R6与第二透镜物侧面的曲率半径R3之间可满足1＜R6/R3＜3，更具体地，R6和R3进一步可满足1.14≤R6/R3≤2.58。合理控制第二透镜第三透镜像侧面的曲率半径R6与第二透镜物侧面的曲率半径R3的比值，可有效地改善球差；同时，还有助于确定第二透镜物侧面以及第三透镜像侧面的形状，保证镜头的加工性。
第三透镜物侧面的曲率半径R5与第三透镜像侧面的曲率半径R6之间可满足|R5+R6|/|R5-R6|＜3，更具体地，R5和R6进一步可满足0.08≤|R5+R6|/|R5-R6|≤2.64。通过对第三透镜物侧面和像侧面曲率半径的 合理控制，使第三透镜不仅能够有效改善系统高级球差，还可同时承担矫正色差的作用。
光学成像镜头的总有效焦距f与第五透镜物侧面的曲率半径R9之间可满足|f/R9|＜1.5，更具体地，f和R9进一步可满足0.30≤|f/R9|≤1.03。通过对第五透镜物侧面曲率半径R9的合理控制，可有效地改善光线在第五透镜上的走势，有利于提升镜头的相对照度。
光学成像镜头的总有效焦距f与第七透镜物侧面的曲率半径R13之间可满足|f/R13|≥2.5，更具体地，f和R13进一步可满足2.55≤|f/R13|≤3.11。通过对第七透镜物侧面曲率半径R13的合理控制，可有效地改善光线在第七透镜上的走势，有利于提升镜头的相对照度。
第三透镜和第四透镜在光轴上的间隔距离T34与第六透镜和第七透镜在光轴上的间隔距离T67之间可满足0＜T34/T67≤1.5，更具体地，T34和T67进一步可满足0.25≤T34/T67≤1.50。合理调整透镜间的间隔距离，有利于减缓光线偏折角度；同时，还有利于改善镜头组装工艺性。
具有光焦度的各透镜分别于光轴上的中心厚度的总和ΣCT与具有光焦度的各透镜中任意相邻的两透镜在光轴上的间隔距离的总和ΣAT之间可满足1＜∑CT/∑AT＜2.5，更具体地，ΣCT和ΣAT进一步可满足1.36≤∑CT/∑AT≤2.39。合理分配光学成像系统内部各透镜的中心厚度以及间隔距离的比例，有助于改善透镜成型以及镜头组装等方面的工艺性。另外，各透镜中心厚度以及间隔距离的合理的比例分配，也有利于保证镜头的小型化。
在包括七片具有光焦度透镜的光学成像系统中，ΣCT＝CT1+CT2+CT3+CT4+CT5+CT6+CT7，其中，CT1为第一透镜于光轴上的中心厚度，CT2为第二透镜于光轴上的中心厚度，CT3为第三透镜于光轴上的中心厚度，CT4为第四透镜于光轴上的中心厚度，CT5为第五透镜于光轴上的中心厚度，CT6为第六透镜于光轴上的中心厚度，CT7为第七透镜于光轴上的中心厚度。∑AT＝T12+T23+T34+T45+T56+T67，其中，T12为第一透镜和第二透镜在光轴上的间隔距离，T23为第二透镜和第三透镜在光轴上的间隔距离，T34为第三透镜和第四透镜在 光轴上的间隔距离，T45为第四透镜和第五透镜在光轴上的间隔距离，T56为第五透镜和第六透镜在光轴上的间隔距离，T67为第六透镜和第七透镜在光轴上的间隔距离。
第二透镜和第三透镜的组合焦距f23与具有光焦度的各透镜中任意相邻的两透镜在光轴上的间隔距离的总和ΣAT之间可满足3.5＜f23/∑AT＜14.5，更具体地，f23和∑AT进一步可满足3.82≤f23/∑AT≤13.79。满足条件式3.5＜f23/∑AT＜14.5可保证镜头的小型化。另外，通过对各透镜轴上间距的调整，可使光线偏折趋于缓和，从而减小相应像差的产生，降低系统敏感性。
光学成像镜头的光学总长度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≤1.6，更具体地，TTL和ImgH进一步可满足1.43≤TTL/ImgH≤1.52。通过对镜头的光学总长度和像高比例的控制，可有效地压缩成像镜头的总尺寸，以实现光学成像镜头的超薄特性与小型化，从而使得该光学成像镜头能够较好地适用于例如便携式电子产品等尺寸受限的系统。
在示例性实施方式中，光学成像镜头还可设置有至少一个光阑，用以提升镜头的成像质量。光阑可根据需要设置于物侧与像侧之间的任意位置处。
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，提出一种可适用于便携带电子产品的，具有大孔径和良好成像质量的光学成像镜头。
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：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。
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它数量的透镜。
