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。
