技术领域
本申请涉及一种摄像镜头，更具体地，涉及一种包括六片透镜的摄像镜头。
背景技术
近年来，随着手机摄像领域的快速发展，以及大尺寸、高像素的互补性氧化金属半导体元件(CMOS)或感光耦合元件(CCD)的芯片的普及，各大手机厂商在追求镜头轻薄化与小型化的同时，更是对镜头的成像质量提出了严苛的要求。当前应用于手机等便携式电子产品的镜头多采用六片式结构，其镜片面型均为旋转对称(轴对称)的非球面。这类旋转对称的非球面可以看成是子午平面内的一条曲线绕光轴旋转360°而形成的，因此其只在子午平面内具有充分的自由度，并不能很好地对轴外像差进行矫正。

在一个实施方式中，第五透镜物侧面的曲率半径R9与第四透镜像侧面的曲率半径R8可满足0＜R9/R8＜1.5。
在一个实施方式中，第三透镜在光轴上的中心厚度CT3与第四透镜在光轴上的中心厚度CT4可满足0.5＜CT3/CT4＜1。
在一个实施方式中，第六透镜在光轴上的中心厚度CT6与第六透镜的边缘厚度ET6可满足0.2＜CT6/ET6＜1。
在一个实施方式中，第五透镜物侧面和光轴的交点至第五透镜物侧面的有效半径顶点在光轴上的距离SAG51与第六透镜物侧面和光轴的交点至第六透镜物侧面的有效半径顶点在光轴上的距离SAG61可满足-0.5＜SAG51/SAG61＜0.5。
在一个实施方式中，摄像镜头还可包括光阑，光阑至摄像镜头的成像面在光轴上的距离SL可满足SL≥4mm。

本申请采用了多片(例如，六片)透镜，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，使得上述摄像镜头具有小型化、大广角和高成像品质等至少一个有益效果。同时，通过引入非旋转对称的非球面，对摄像镜头的轴外子午像差和弧矢像差进行矫正，进一步获得像质的提升。

具体实施方式
为了更好地理解本申请，将参考附图对本申请的各个方面做出更详细的说明。应理解，这些详细说明只是对本申请的示例性实施方式的描述，而非以任何方式限制本申请的范围。在说明书全文中，相同的附图标号指代相同的元件。表述“和/或”包括相关联的所列项目中的一个或多个的任何和全部组合。
应注意，在本说明书中，第一、第二、第三等的表述仅用于将一个特征与另一个特征区分开来，而不表示对特征的任何限制。因此，在不背离本申请的教导的情况下，下文中讨论的第一透镜也可被称作第二透镜或第三透镜。
在附图中，为了便于说明，已稍微夸大了透镜的厚度、尺寸和形状。具体来讲，附图中所示的球面或非球面的形状通过示例的方式示出。即，球面或非球面的形状不限于附图中示出的球面或非球面的形状。附图仅为示例而并非严格按比例绘制。
在本文中，近轴区域是指光轴附近的区域。若透镜表面为凸面且未界定该凸面位置时，则表示该透镜表面至少于近轴区域为凸面；若透镜表面为凹面且未界定该凹面位置时，则表示该透镜表面至少于近轴区域为凹面。每个透镜中，最靠近被摄物的表面称为该透镜的物侧面；每个透镜中，最靠近成像面的表面称为该透镜的像侧面。
在本文中，我们定义平行于光轴的方向为Z轴方向，与Z轴垂直且位于子午平面内的方向为Y轴方向，与Z轴垂直且位于弧矢平面内的方向为X轴方向。除与视场相关的数据以外，未标明X、Y方向的数据，均按Y方向的数值呈现。
还应理解的是，用语“包括”、“包括有”、“具有”、“包含”和/或“包含有”，当在本说明书中使用时表示存在所陈述的特征、元件和/或部件，但不排除存在或附加有一个或多个其它特征、元件、部件和/或它们的组合。此外，当诸如“...中的至少一个”的表述出现在所列特征的列表之后时，修饰整个所列特征，而不是修饰列表中的单独元件。此外，当描述本申请的实施方式时，使用“可”表示 “本申请的一个或多个实施方式”。并且，用语“示例性的”旨在指代示例或举例说明。
除非另外限定，否则本文中使用的所有用语(包括技术用语和科学用语)均具有与本申请所属领域普通技术人员的通常理解相同的含义。还应理解的是，用语(例如在常用词典中定义的用语)应被解释为具有与它们在相关技术的上下文中的含义一致的含义，并且将不被以理想化或过度正式意义解释，除非本文中明确如此限定。
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。以下将参考附图并结合实施例对本申请的特征、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摄像镜头可包括例如六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、第五透镜和第六透镜。这六片透镜沿着光轴由物侧至像侧依序排列，各相邻透镜之间均可具有空气间隔。
在示例性实施方式中，第一透镜可具有负光焦度；第二透镜可具有正光焦度；第三透镜可具有负光焦度；第四透镜具有正光焦度或负光焦度；第五透镜具有正光焦度或负光焦度；第六透镜具有负光焦度。第一透镜为负光焦度，有利于减小入射光线的倾角，从而对物方大视场实现有效分担，获得更大的视场角范围；在此基础上，第二透镜为正光焦度，同第一透镜进行组合，有利于对不同视场像差的矫正；当配置第六透镜光焦度为负时，有利于矫正光学系统场曲，提高成像质量。
此外，可以将第一透镜至第六透镜中的至少一个透镜的物侧面和/或像侧面设置为非旋转对称的非球面，来进一步提升像质。非旋转对称的非球面是一种自由曲面，在旋转对称的非球面基础上，增加了非旋转对称分量，因而在透镜系统中引入非旋转对称的非球面有利于通过对轴外子午像差和弧矢像差进行有效矫正，极大地提升光学系统的性能。
在示例性实施方式中，第一透镜的像侧面可为凹面。
在示例性实施方式中，第二透镜的物侧面可为凸面，像侧面可为凸面。
在示例性实施方式中，第四透镜可具有负光焦度，其物侧面和像侧面中的至少一个可为凹面。可选地，第四透镜的像侧面为凹面。
在示例性实施方式中，第五透镜可具有正光焦度，其物侧面可为凸面，像侧面可为凸面。
在示例性实施方式中，第六透镜的像侧面可为凹面。
在示例性实施方式中，本申请的摄像镜头可满足条件式0.5＜fx/fy＜1.5，其中，fx为摄像镜头X轴方向的有效焦距，fy为摄像镜头Y轴方向的有效焦距。更具体地，fx和fy进一步可满足0.86≤fx/fy≤1.24。合理配置X轴、Y轴方向的焦距比值，有利于提升自由曲面在两个方向上的自由度，优化系统对于轴外像差的矫正作用；同时，有利于将光学系统的像差和各项参数控制在一个较合适的范围内，最终获得高质量的图像。
在示例性实施方式中，本申请的摄像镜头可满足条件式FOV＞90°，其中，FOV为摄像镜头的全视场角。更具体地，FOV进一步可满足FOV＞100°，例如，110.4°≤FOV≤120.8°。满足条件式FOV＞90°，有利于获得较大的视场角，提高光学系统对物方信息的收集能力。
在示例性实施方式中，本申请的摄像镜头可满足条件式TTL/ImgH＜1.8，其中，TTL为第一 透镜的物侧面的中心至摄像镜头的成像面在光轴上的距离，ImgH为摄像镜头的成像面上有效像素区域对角线长的一半。更具体地，TTL和ImgH进一步可满足1.62≤TTL/ImgH≤1.79。通过约束TTL和ImgH的比值，实现摄像镜头的超薄化和高成像质量。
在应用中，还可以对各透镜的有效焦距进行合理优化。例如，第二透镜的有效焦距f2与第一透镜的有效焦距f1可满足-0.6＜f2/f1＜-0.4。更具体地，f2和f1进一步可满足-0.58≤f2/f1≤-0.46。又例如，第五透镜的有效焦距f5与第六透镜的有效焦距f6可满足0.5＜|1/f5-1/f6|＜2.5。更具体地，f5和f6进一步可满足0.60≤|1/f5-1/f6|≤2.29。合理配置各透镜的光焦度，有利于各类像差的矫正，同时有利于提升摄像镜头的成像质量。
在示例性实施方式中，本申请的摄像镜头可满足条件式0＜R9/R8＜1.5，其中，R9为第五透镜物侧面的曲率半径，R8为第四透镜像侧面的曲率半径。更具体地，R9和R8进一步可满足0.36≤R9/R8≤1.28。合理配置第五透镜物侧面和第四透镜像侧面的曲率半径，可以有效消除系统球差，获得高清晰度的图像。
在示例性实施方式中，本申请的摄像镜头可满足条件式0.5＜CT3/CT4＜1，其中，CT3为第三透镜在光轴上的中心厚度，CT4为第四透镜在光轴上的中心厚度。更具体地，CT3和CT4进一步可满足0.57≤CT3/CT4≤0.94。合理配置透镜中心厚度，可以有效降低镜头的厚度敏感性，矫正场曲。
在示例性实施方式中，本申请的摄像镜头可满足条件式0.2＜CT6/ET6＜1，其中，CT6为第六透镜在光轴上的中心厚度，ET6为第六透镜的边缘厚度。更具体地，CT6和ET6进一步可满足0.38≤CT6/ET6≤0.90。合理配置透镜的厚薄比，有利于满足镜头的可加工性和工艺性要求。
在示例性实施方式中，本申请的摄像镜头可满足条件式-0.5＜SAG51/SAG61＜0.5，其中，SAG51为第五透镜物侧面和光轴的交点至第五透镜物侧面的有效半径顶点在光轴上的距离，SAG61为第六透镜物侧面和光轴的交点至第六透镜物侧面的有效半径顶点在光轴上的距离。更具体地，SAG51和SAG61进一步可满足-0.36≤SAG51/SAG61≤0.10。合理配置面型，可以有效消除系统场曲，确保成像质量。
在示例性实施方式中，上述摄像镜头还可包括光阑，以提升镜头的成像质量。可选地，光阑可设置在第一透镜与第二透镜之间。可选地，光阑至摄像镜头的成像面在光轴上的距离SL可满足SL≥4mm。更具体地，SL进一步可满足4.01≤SL≤4.24。合理配置光阑位置，可以有效降低系统公差敏感性，提高设计良率。
可选地，上述摄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摄像镜头可采用多片镜片，例如上文所述的六片。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，可有效地缩小镜头的体积、降低镜头的敏感度并提高镜头的可加工性，使得摄像镜头更有利于生产加工并且可适用于便携式电子产品。通过引入非旋转对称的非球面，对摄像镜头的轴外子午像差和弧矢像差进行矫正，可以获得进一步的像质提升。
在本申请的实施方式中，各透镜的镜面多为非球面镜面。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，可改变构成摄像镜头的透镜数量，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。
