Description

摄远镜头以及摄像装置 技术领域
本申请涉及摄远镜头以及装配有这种摄远镜头的摄像装置。
背景技术
随着CCD(charge-coupled device，电耦合器件)及CMOS(complementary metal-oxide semiconductor，互补式金属氧化物半导体)图像传感器的性能提高及尺寸减小，对应的摄远镜头也需满足高成像品质及小型化的要求。
此外，随着人们对便携式电子产品的成像质量的要求越来越高，手机、平板电脑等电子产品将变得更薄、体积更小。为了满足小型化，需要尽可能地减少成像镜头的镜片数量，但是由此造成的设计自由度的缺乏会难以满足市场对高成像性能的需求。目前主流摄远镜头为了获得宽视角的图像，采用广角光学系统，但是这不利于拍摄较远物体，无法获得清晰的图像。

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远镜头。根据本申请的示例性实施方式的摄远镜头沿着光轴从物侧至像侧可依次设置有第一透镜、第二透镜、第三透镜、第四透镜、至少一个后续透镜以及感光元件，并且该摄远镜头可具有总有效焦距f。
在示例性实施方式中，第一透镜可具有正光焦度，其物侧面可为凸面。第一透镜的物侧面至成像面的轴上距离TTL与摄远镜头的总有效焦距f之间可满足TTL/f≤1.0，更具体地，满足TTL/f≤0.99。第四透镜可具有正光焦度。第一透镜的有效焦距f1、第四透镜的有效焦距f4与总有效焦距f之间可满足：1＜|f/f1|+|f/f4|≤2.7，更具体地，满足1.16≤|f/f1|+|f/f4|≤2.7。通过合理设置第一透镜的物侧面至摄远镜头的成像面之间的距离，可使得镜头尽可能地薄。此外，通过合理地选择各透镜的焦距并适当地调整摄远镜头的总有效焦距，能够使摄远镜头获得较好的平场条件。
在示例性实施方式中，第一透镜可设置成其有效焦距f1与摄远镜头的总有效焦距f之间满足：0.45＜f1/f≤1.0，更具体地，满足0.46≤f1/f≤1.0，以保证第一透镜承担适当的正光焦度，从而便于后续透镜的设计。
在示例性实施方式中，第二透镜可具有负光焦度，其像侧面可设置为凹面。第二透镜的有效焦距f2与摄远镜头的总有效焦距f之间可满足：-1.5＜f2/f＜-0.7，更具体地，满足-1.48≤f2/f≤-0.77。通过合理设置第二透镜的有效焦距来确保第二透镜能够产生一定的正球差，以平衡正光焦度透镜的负球差；如果第二透镜的有效焦距f2与摄远镜头的总有效焦距f之间的比值小于下限值，则矫正能力不足，若大于上限值，则产生过多的正球差。
在示例性实施方式中，第三透镜的有效焦距f3、第四透镜的有效焦距f4与总有效焦距f之间可满足：|f/f3|+|f/f4|＜1.5，更具体地，满足|f/f3|+|f/f4|≤1.44。通过合理配置第三透镜的有效焦距f3和第四透镜的有效焦距f4之间的关系可确保系统获得适当的相对亮度。
在示例性实施方式中，第四透镜的物侧面的曲率半径R7与其像侧面的曲率半径R8之间可满足：|(R7+R8)/(R7-R8)|≤2，例如，满足|(R7+R8)/(R7-R8)| ≤1.92。通过使第四透镜的曲率半径差异尽可能大，从而确保其具有较强的平衡像差的能力。
在示例性实施方式中，第二透镜和第三透镜之间的轴上空气间隔T23与第三透镜和第四透镜之间的轴上空气间隔T34之间可满足：T34/T23＜2.5，例如T34/T23≤2.3。通过合理地选择第二透镜和第三透镜的轴向位置，能够很好的矫正匹兹伐场曲。
在示例性实施方式中，第二透镜的物侧面的曲率半径R3与其像侧面的曲率半径R4之间可满足：|(R3+R4)/(R3-R4)|≤2，例如|(R3+R4)/(R3-R4)|≤1.8。通过合理地分配第二透镜的曲率，可使得第二透镜具有合适的赛德像差系数，从而能够较好地平衡初级像差。
在示例性实施方式中，第三透镜的物侧面的曲率半径R5与其像侧面的曲率半径R6之间可满足：|(R5-R6)/(R5+R6)|≤1，更具体地，例如满足|(R5-R6)/(R5+R6)|≤0.97。通过合理地设置第三透镜的曲率，可有效地矫正球差。
在示例性实施方式中，摄远镜头中的至少一个后续透镜可包括具有负光焦度的第五透镜，其物侧面为凹面。第五透镜的物侧面在最大有效径处的矢高SAG51与其中心厚度CT5之间可满足：|SAG51/CT5|＜4.0，更具体地，可满足|SAG51/CT5|≤3.56。
在示例性实施方式中，第五透镜的有效焦距f5与摄远镜头的总有效焦距f之间可满足：-1.5＜f5/f＜-0.5，更具体地，满足-1.26≤f5/f≤-0.52，以使第五透镜承担适当的负光焦度。
在示例性实施方式中，第一透镜、第二透镜、第三透镜、第四透镜和第五透镜的中心厚度CT1、CT2、CT3、CT4和CT5之间可满足：0.5＜(CT2+CT3+CT5)/(CT1+CT4)＜1.0，更具体地，可满足：0.56≤(CT2+CT3+CT5)/(CT1+CT4)≤0.95。通过合理地选择各透镜的厚度，能够合理地矫正五阶球差和色球差。如果(CT2+CT3+CT5)/(CT1+CT4)小于下限值，则五阶球差显著增加，而如果(CT2+CT3+CT5)/(CT1+CT4)大于上限值，则色球差显著增加。
本申请还提供了另一种摄远镜头。该摄远镜头沿着光轴从物侧至像侧可依次包括第一透镜、第二透镜、第三透镜以及多个后续透镜。在该摄远镜头中， 第一透镜的物侧面至成像面的轴上距离TTL与摄远镜头的总有效焦距f之间可满足：TTL/f≤1.0，例如，TTL/f≤0.99，并且第三透镜的物侧面的曲率半径R5与其像侧面的曲率半径R6之间可满足：|(R5-R6)/(R5+R6)|≤1，例如|(R5-R6)/(R5+R6)|≤0.97。这样设计的摄远镜头在确保镜头尽可能地薄的情况下可有效地矫正球差。
在另一示例性实施方式中，第一透镜可设置成其有效焦距f1与摄远镜头的总有效焦距f之间满足：0.45＜f1/f≤1.0，更具体地，满足0.46≤f1/f≤1.0，以保证第一透镜承担适当的正光焦度，从而便于后续透镜的设计。
在另一示例性实施方式中，第二透镜可具有负光焦度，其像侧面可设置为凹面。第二透镜的有效焦距f2与摄远镜头的总有效焦距f之间可满足：-1.5＜f2/f＜-0.7，更具体地，满足-1.48≤f2/f≤-0.77。通过合理设置第二透镜的有效焦距来确保第二透镜能够产生一定的正球差，以平衡正光焦度透镜的负球差；如果第二透镜的有效焦距f2与摄远镜头的总有效焦距f之间的比值小于下限值，则矫正能力不足，若大于上限值，则产生过多的正球差。
在另一示例性实施方式中，第二透镜的物侧面的曲率半径R3与其像侧面的曲率半径R4之间可满足：|(R3+R4)/(R3-R4)|≤2，例如|(R3+R4)/(R3-R4)|≤1.8。通过合理地分配第二透镜的曲率，可使得第二透镜具有合适的赛德像差系数，从而能够较好地平衡初级像差。
在另一示例性实施方式中，第二透镜和第三透镜之间的轴上空气间隔T23与第三透镜和第四透镜之间的轴上空气间隔T34之间可满足：T34/T23＜2.5，例如T34/T23≤2.3。通过合理地选择第二透镜和第三透镜的轴向位置，能够很好的矫正匹兹伐场曲。
在另一示例性实施方式中，摄远镜头中的多个后续透镜还可包括具有正光焦度的第四透镜。第三透镜的有效焦距f3、第四透镜的有效焦距f4与该摄远镜头的总有效焦距f之间可满足：|f/f3|+|f/f4|＜1.5，更具体地，可满足|f/f3|+|f/f4|≤1.44。通过合理配置第三透镜的有效焦距f3和第四透镜的有效焦距f4之间的关系可确保系统获得适当的相对亮度。
在另一示例性实施方式中，第四透镜的物侧面的曲率半径R7与其像侧面的曲率半径R8之间可满足：|(R7+R8)/(R7-R8)|≤2，例如，满足|(R7+R8)/(R7-R8)|≤1.92。通过使第四透镜的曲率半径差异尽可能大，从而确保其具有较强的平 衡像差的能力。
在另一示例性实施方式中，第一透镜的有效焦距f1、第四透镜的有效焦距f4与总有效焦距f之间可满足：1＜|f/f1|+|f/f4|≤2.7，更具体地，满足1.16≤|f/f1|+|f/f4|≤2.7。通过合理地选择各透镜的焦距并适当地调整摄远镜头的总有效焦距，能够使摄远镜头获得较好的平场条件。
在另一示例性实施方式中，摄远镜头中的多个后续透镜还可包括第五透镜。第五透镜可具有负光焦度，且其物侧面可为凹面。第五透镜的物侧面在最大有效径处的矢高SAG51与其中心厚度CT5之间可满足：|SAG51/CT5|＜4.0，更具体地，可满足|SAG51/CT5|≤3.56。
在另一示例性实施方式中，第五透镜的有效焦距f5与摄远镜头的总有效焦距f之间可满足：-1.5＜f5/f＜-0.5，更具体地，满足-1.26≤f5/f≤-0.52，以使第五透镜承担适当的负光焦度。
在另一示例性实施方式中，第一透镜、第二透镜、第三透镜、第四透镜和第五透镜的中心厚度CT1、CT2、CT3、CT4和CT5之间可满足：0.5＜(CT2+CT3+CT5)/(CT1+CT4)＜1.0，更具体地，可满足：0.56≤(CT2+CT3+CT5)/(CT1+CT4)≤0.95。通过合理地选择各透镜的厚度，能够合理地矫正五阶球差和色球差。如果(CT2+CT3+CT5)/(CT1+CT4)小于下限值，则五阶球差显著增加，而如果(CT2+CT3+CT5)/(CT1+CT4)大于上限值，则色球差显著增加。
本申请还提供了一种摄像装置。该摄像装置可包括如上所述的摄远镜头。
根据本申请的上述实施方式的摄远镜头可采用多片镜片，例如在本申请中采用5片，但应理解这只是示例而非限制。通过合理分配各透镜的光焦度、中心厚度、面型、各透镜之间的轴上间距等，可提供一种具有高分辨率且小型化的摄远镜头。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，在未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个结果和优点。例如，虽然在第一实施方式中的描述中采用由五个透镜为例进行了描述，但是该摄远镜头不限于包括五个透镜。如果需要，该摄远镜头还可包括其它数量的透镜。
