以下结合具体实施例进一步描述本申请。
实施例1
首先参照图1至图2D描述根据本申请实施例1的光学成像系统。
图1为示出根据本申请实施例1的光学成像系统的结构示意图。光学成像系统沿着光轴从物侧至像侧依序包括具有正光焦度的第一透镜组、具有负光焦度第二透镜组和至少一个后续透镜组。
如图1所示，第一透镜组可包括具有正光焦度的第一透镜E1和第二透镜E2。通过设置两个具有正光焦度的透镜，可有利于分散正光焦度，避免光焦度过度集中，同时可有效减小色球差以及轴向色差。第一透镜E1的像侧面S2可随着远离光轴而由凹面逐渐变为凸面，这样的结构可在加大通光量的同时减小边缘视场的像差。
第二透镜组可包括具有负光焦度的第三透镜E3。如图1所示，实施例1中的第二透镜的物侧面S3和像侧面S4均为凸面。
第一透镜E1和第二透镜E2的合成焦距f12与第三透镜E3的有效焦距f3满足-0.5＜f12/f3＜0，例如-0.46≤f12/f3≤-0.32，在本实施例中f12/f3＝-0.34。适当分配上述两项的光焦度，可有效减小整个系统的像差，降低系统敏感性。上述透镜组中的各透镜的焦距设置将在下面参照表3进行描述。
在实施例1的光学成像系统中，至少一个后续透镜组可包括具有负光焦度的第三透镜组。第三透镜组可包括具有光焦度的第四透镜E4和具有光焦度的第五透镜E5，其中，第五透镜E5的物侧面S9在近轴处为凸面，而其像侧面S10在近轴处为凹面。
可选地，光学成像系统还可包括具有物侧面S11和像侧面S12的滤色片E6以滤除红外光。在本实施例的光学成像系统中，还可设置有光圈STO以调解进光量。来自物体的光依序穿过各表面S1至S12并最终成像在成像表面S13上。
在本实施例中，各镜面S1-S10中的至少一个镜面为非球面镜面。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。

表1
由表1可得，第三透镜E3的物侧面S5的曲率半径R5和像侧面S6的曲率半径R6满足0＜(R5-R6)/(R5+R6)＜0.5，例如0.27≤(R5-R6)/(R5+R6)≤0.45，在本实施例中，(R5-R6)/(R5+R6)＝0.29。通过合理配置第三透镜E3的两个镜面的曲率半径，有助于修正系统整体像差。另外，第二透镜E2的像侧面S4的曲率半径R4与第三透镜E3的物侧面S5的曲率半径R5满足-1.2＜R5/R4＜0，例如-1.06≤R5/R4≤ -0.35，在本实施例中，R5/R4＝-0.38。通过合理配置第二透镜E2和第三透镜E3的相邻镜面，可有助于减少球差以及象散的产生。
本实施例采用了5片透镜作为示例，通过合理分配各透镜的焦距与面型，有效改善了光学成像系统的像差，实现了优良的解像力性能，同时保证光学成像系统的小型化。各个镜面的面型由以下公式限定：
Z＝ch2/[1+{1-(1+k)c2h2}+1/2]+A4h4+A6h6+A8h8+A10h10+A12h12+A14h14+A16h16
其中，Z为距镜面顶点的切平面的距离，c为镜面的近轴曲率，h为距主光轴的高度，k为圆锥系数，A4至A16分别为相应高次项系数。下表2示出了实施例1中可用于各镜面S1-S10的高次项系数A4、A6、A8、A10、A12和A16。

表2
以下所示出的表3给出实施例1的各透镜的有效焦距f1至f5、光学成像系统的总有效焦距f、光学成像系统的总长度TTL以及半视场(对角线)角度HFOV。

f3(mm) -8.23 HFOV(deg) 41.1
f4(mm) 74.10    
f5(mm) -20.40    
表3
根据表3，第一透镜E1的有效焦距f1与光学成像系统的总有效 焦距f满足0.3≤f/f1≤0.5，例如0.34≤f/f1≤0.46，在本实施例中，f/f1＝0.38。通过合理地配置第一透镜E1的有效焦距f1与光学成像系统的总有效焦距f之间的关系，可有助于缩短系统总长，同时矫正球差。根据表1和表3，第二透镜E2的有效焦距f2与第二透镜E2的像侧面S4的曲率半径R4满足f2/|R4|≤0.6，例如，f2/|R4|≤0.56，在本实施例中f2/|R4|＝0.33。通过合理地配置第二透镜E2的有效焦距和镜面参数，可有助于矫正球差以及象散，快速修正近轴像差，提升中心区域的成像品质。另外，第四透镜E4的物侧面S7的曲率半径R7与光学成像系统的总有效焦距f满足f/|R7|≤0.6，例如f/|R7|≤0.59，在本实施例中，f/|R7|＝0.46。
可通过调整第四透镜E4物侧面S7的曲率半径来调整系统边缘像差。
本光学成像系统的总有效焦距f与入瞳直径EPD满足f/EPD≤2.0，例如在本实施中，f/EPD＝1.78。这可有利于加大通光量，使系统具有大光圈优势，增强暗环境下的成像效果。
另外，第三透镜E3和第四透镜E4配置为使得其各自的色散系数V3和V4满足|V3-V4|≤10，例如，在本实施例中，|V3-V4|＝3.10。通过合理配置第三透镜E3和第四透镜E4的色散系数，可有效修正色差，平衡高级像差，提升成像品质。
在实施例1中，第三透镜E3和第四透镜E4在光轴上的间隔距离T34与从第一透镜E1的物侧面S1到光学成像系统的成像面S13的轴上距离TTL满足T34/TTL＜0.2，例如T34/TTL≤0.18，在本实施例中T34/TTL＝0.12。通过合理地布置透镜间距以及光学系统的总长，可有助于缓和系统边缘光线走势，降低高级像差，同时降低系统敏感性。另外，第三透镜E3的中心厚度CT3与第四透镜E4的中心厚度CT4满足CT3/CT4≤0.4，例如，CT3/CT4≤0.36，在本实施例中，CT3/CT4＝0.31。这可有利于保证镜片成型工艺性以及组装稳定性，用第四透镜来弥补第三透镜高级像差的矫正效果。第四透镜E4和第五透镜E5的合成焦距f45与光学成像系统的总有效焦距f满足-0.5＜f/f45＜0，例如，-0.39≤f/f45≤-0.12，在本实施例中，f/f45＝-0.12。 这样可有助于调配第四透镜和第五透镜的光焦度分配，降低公差敏感性，并维持系统小型化。
