以下对本申请的特征、原理和其他方面进行详细描述。
本申请提供了一种摄像镜头。根据本申请的示例性实施方式，该摄像镜头沿着光轴从物侧至成像侧可依次设置有第一透镜、第二透镜、第三透镜、第四透镜、第五透镜和第六透镜。该摄像镜头可具有有效焦距f。
在示例性实施方式中，第一透镜具有负光焦度，其物侧面凸面；第三透镜具有正光焦度，其物侧面凸面；第六透镜具有负光焦度，其物侧面凹面。第二透镜、第四透镜和第五透镜均可具有光焦度。可选地，第二透镜可具有正光焦度或负光焦度。可选地，第四透镜可具有 正光焦度或负光焦度。可选地，第五透镜可具有正光焦度或负光焦度。
在示例性实施方式中，第一透镜像侧面为凹面，第三透镜像侧面为凸面。通过合理的分配光焦度和透镜面型，使得系统的初级像差较为合理，并且将第一透镜的像侧面设置为凹面有利于缩短摄像镜头的整体长度，减小摄像镜头的体积，从而实现镜头的小型化。
在应用中，可以对各透镜的光焦度进行合理有效分配，来进行初级像差及系统垂轴色差和轴向色差的有效控制，有效的提升摄像镜头的成像性能，同时保证镜头紧凑，且视场角较大。例如，在示例性实施方式中，第一透镜的有效焦距f1与摄像镜头的有效焦距f之间满足：-6＜f1/f＜-3，更具体地，可满足-5.145≤f1/f≤-3.828。又例如，第一透镜的有效焦距f1与第三透镜的有效焦距f3之间满足：-10＜f1/f3＜-5，更具体地，可满足-8.568≤f1/f3≤-6.476。将第一透镜的光焦度控制在上述合理的区间，能有效的控制系统的球差和慧差。再例如，第六透镜的有效焦距f6与摄像镜头的有效焦距f之间满足：-1＜f6/f＜-0.5，更具体地，可满足-0.641≤f6/f≤-0.574。第六透镜的合理焦度配置，能有效的保证系统的整体光焦度和像高。
在应用中，可以对各透镜在光轴上的中心厚度进行优化。对摄像镜头中各透镜的尺寸结构进行合理布局，有利于控制摄像镜头的色球差，使摄像镜头的畸变控制在合理的区间，同时还可实现镜头横向尺寸的压缩，从而保证镜头的紧凑性和小型化。例如，在示例性实施方式中，第一透镜在光轴上的中心厚度CT1与第二透镜在光轴上的中心厚度CT2之间可满足：0.6＜CT1/CT2＜1.2，更具体地，可满足0.717≤CT1/CT2≤1.03。通过对第一透镜的中心厚度与第二透镜的中心厚度的合理分配，可有效的控制摄像镜头的色球差。又例如，第三透镜在光轴上的中心厚度CT3与第五透镜在光轴上的中心厚度CT5之间满足：0.8＜CT3/CT5＜1.3，更具体地，可满足0.924≤CT3/CT5≤1.214。通过对第三透镜和第五透镜的厚度的合理分配，能有效的将摄像镜头的畸变控制在合理的区间内。
在应用中，通过合理地配置曲率半径和镜片形状，能够提升相对照度，有利于修正像差，从而使得摄像镜头具有高成像品质。例如， 在示例性实施方式中，第一透镜物侧面径R1与第六透镜物侧面的曲率半径R11之间可满足：-1.2＜R1/R11＜-0.7，更具体地，可满足-1.125≤R1/R11≤-0.867。通过对第一透镜曲率和第六透镜曲率区间的控制，能有效的控制摄像镜头的象散量。又例如，第一透镜物侧面的曲率半径R1与第三透镜物侧面的曲率半径R5之间可满足：1＜R1/R5＜1.5，更具体地，可满足1.296≤R1/R5≤1.449。通过控制第一透镜物侧面曲率和第三透镜物侧面曲率，来实现低阶像差的有效平衡和像质的有效提升。
为了确保摄像镜头在组装过程中的结构定位的稳定性，避免由于第一透镜与第二透镜的定位口径差所造成的弯曲变形。可以将第一透镜物侧面的有效半径DT11与第二透镜物侧面的有效半径DT21配置成可满足：1＜DT11/DT21＜1.5，更具体地，可满足1.346≤DT11/DT21≤1.411。通过对第一透镜和第二透镜的物侧面半径的约束，可有效地实现系统的小型化，以此减轻系统的重量。
在示例性实施方式中，第一透镜物侧面至成像面在光轴上的距离TTL与电子光感元件有效像素区域对角线长的一半ImgH之间满足：TTL/ImgH＜1.8，更具体地，可满足TTL/ImgH≤1.728。通过TTL与像高的比例的约束，能有效的控制系统的紧凑性。
在示例性实施方式中，第一透镜物侧面的有效半径DT11与电子光感元件有效像素区域对角线长的一半ImgH之间满足：0.3＜DT11/ImgH＜0.6，更具体地，可满足0.397≤DT11/ImgH≤0.421。通过优化第一透镜的口径，能有效地减小光学摄像镜头的前端面开孔直径，使得该摄像镜头应用于手机前摄的时候，可有效的提升前端面的美观性
在示例性实施方式中，第一透镜和第二透镜在光轴上的间隔距离与第四透镜和第五透镜在光轴上的间隔距离T45之间满足：0.8＜T12/T45＜1.3，更具体地，可满足0.994≤T12/T45≤1.214。通过控制第一二块透镜的间距和第四五块透镜间距的比例，能有效的控制摄像镜头的五阶球差的贡献率，进而可以有效的控制摄像镜头的感度。
在示例性实施方式中，第四透镜和第五透镜在光轴上的间隔距离 T45与第五透镜和第六透镜在光轴上的间隔距离T56之间满足：0.5＜T45/T56＜1，更具体地，可满足0.803≤T45/T56≤0.902。通过控制第四五透镜和第五六透镜的间距在上述范围内，能有效的控制摄像镜头的场曲。
根据本申请的上述实施方式的摄像镜头可采用多片镜片，例如在本申请中采用6片，但应理解这只是示例而非限制。通过合理设置各透镜的光焦度、中心厚度、面型、各透镜之间的轴上间距等，可提供一种高亮度、高解像力的紧凑型摄像镜头。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：从透镜中心到周边曲率是连续变化的。与从透镜中心到周边有一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。
然而，本领域的技术人员应当理解，在不背离本申请要求保护的技术方案的情况下，可改变镜头的构成数量，来获得下面描述的各种结果和优点。例如，虽然在第一实施方式中的描述中采用由六个透镜为例进行了描述，但是该摄像镜头不限于包括六个透镜。如果需要，该摄像镜头还可包括其它数量的透镜。
下面参照附图进一步描述可适用于上述实施方式的摄像镜头的具体实施例。
