技术领域
本申请涉及一种光学成像镜头，更具体地，涉及一种由八片镜片组成的光学成像镜头。
背景技术
随着科技的发展，半导体工艺技术不断精进，因此，高品质成像镜头逐渐成为市场主流趋势。随着手机、平板电脑等便携式电子产品的日益发展而变得越来越薄、体积越来越小，特别是目前市场越来越大的360环视应用，对光学成像镜头的小型化、轻量化及成像质量等性能提出了进一步更高的要求。
为了满足小型化、高品质的要求，智能手机等便携式电子产品的不断发展，对成像镜头提出了更高的要求，特别是针对光线不足等环境如阴雨天、傍晚、夜景、星空等情况，故此2.0或2.0以上的F数已经无法满足更高阶的成像要求，为了获得更大的进光量，需要F数更小的成像镜头。为了满足更高的成像质量，为用户带来更加的成像体验，需要更多的镜片数量来实现，多片数的镜头成为高端市场领域的主流产品。

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片镜片，例如上文所述的八片。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八个透镜为例进行了描述，但是该光学成像镜头不限于包括八个透镜。如果需要，该光学成像镜头还可包括其它数量的透镜。
