Description

光学成像系统、取像装置和光学装置 技术领域
本公开涉及光学成像技术领域，尤其是涉及一种光学成像系统、取像装置和光学装置。
背景技术
随着手机、平板电脑、无人机、计算机等电子产品在生活中的广泛应用，各种科技改进推陈出新。其中，新型电子产品改进中摄像镜头拍摄效果的改进创新成为人们关注的重心之一，同时成为科技改进的一项重要内容，能否使用微型摄像元件拍摄出高画质感、高分辨率、高清晰度，甚至暗光条件下能拍摄出画质清晰的图片成为现代人选择何种电子产品的关键因素。另一方面，光电耦合器(CCD)及互补金属氧化物半导体(CMOS)等感光元件伴随着科技进步在性能上的改进，为拍摄高质量的像质提供了可能，给人们带来了更高画质感的拍摄体验。因此，光学成像系统设计的微型化及性能改进成为目前摄像头提升拍摄质量的关键因素。
发明内容
本公开旨在至少解决现有技术中存在的技术问题之一。为此，本公开的一个目的在于提出一种光学成像系统，在满足微型设计的同时，增大了通光口径，有更大的进光量，可满足高清晰图像及暗光拍摄的需求。
本公开还提出了一种取像装置。
本公开进一步提出了一种光学装置。
根据本公开第一方面实施例的光学成像系统，由物侧至像侧依次包括：
一具有正曲折力的第一透镜，所述第一透镜的物侧面近轴区域为凸面；
一具有正曲折力的第二透镜，所述第二透镜的物侧面近轴区域为凹面且像侧面近轴区域为凸面；
一具有负曲折力的第三透镜，所述第三透镜的物侧面近轴区域为凸面且像侧面近轴区域为凹面；
—具有负曲折力的第四透镜，所述第四透镜的物侧面近轴区域为凹面；
—具有正曲折力的第五透镜，所述第五透镜的物侧面近轴区域为凸面；
—具有负曲折力的第六透镜，所述第六透镜的像侧面近轴区域为凹面；
所述光学成像系统满足关系式：
Fno/TTL<0.4，0.2<GTL6/ITL6<0.3；
其中，Fno为光学透镜组光圈数，TTL为第一透镜物侧面至成像面于光轴上的距离，GTL6为第六透镜物侧面到像侧面平行于光轴处最短的距离，ITL6为第六透镜物侧面到像侧面平行于光轴处最长的距离。
当Fno/TTL>0.4,兼顾小型化的同时会造成光学系统通光量不足，拍摄出的画面清晰度下降。 根据本公开的光学成像系统，当Fno/TTL＜0.4时，可以使镜头系统可以满足大光圈及小型化设计要求，为摄像提供足够的通光量，满足高画质高清晰拍摄需要。此外，所述光学成像系统还满足关系式：0.2<GTL6/ITL6<0.3，GTL6为第六透镜物侧面到像侧面平行于光轴处最短(薄)的距离，ITL6为第六透镜物侧面到像侧面平行于光轴处最长(厚)的距离。当GTL6/ITL6满足该上述关系式时，即合理的控制了透镜厚薄比，使该镜片实现光轴处超薄设计，可有效压缩镜头总长度，并且可以保证镜片的可加工性及成型良率。
根据本公开的一些实施例，所述光学成像系统满足下列关系式：1.5<TTL/DL<3.0。其中，TTL为第一透镜物侧面至光学成像系统成像面于光轴上的距离，DL为光学成像系统光阑孔径直径大小。
当TTL/DL满足上述关系式时，才能保证镜头小型化设计并提供镜头拍摄所需的通光量，实现高画质高清晰的拍摄效果，当TTL/DL<1.5时，满足小型化设计时通光口径会过大，造成边缘光线进入成像系统，降低成像质量，如果TTL/DL>3，满足小型化的同时，会造成光阑通光口径过小，无法满足系统通光量，实现不了暗光场景高清晰拍摄要求，因此只有满足1.5<TTL/DL<3.0才能同时兼顾光学性能最优化，结构小型化。
根据本公开的一些实施例，所述光学成像系统满足下列关系式：0.5<DL/Imgh<0.8。其中，DL为所述光学成像系统的光阑孔径直径，Imgh为光学成像系统成像面上电子感光元件有效像素区域对角线长的一半。光学成像系统光阑孔径直径大小决定了整个光学成像系统通光量大小，感光面尺寸大小决定了整个摄像系统画面清晰度及像素大小。
当DL/Imgh满足上述关系式时，两者合理配合才能保证足够的通光量，保证拍摄图像清晰度。如果DL/Imgh>0.8,则会造成曝光过大，光亮度太高，影响画面质量，DL/Imgh<0.5,则会造成通光量不足，光线相对亮度不够时会造成画面清晰度下降。
根据本公开的一些实施例，所述光学成像系统满足下列关系式：TTL/Imgh<1.5。其中，Imgh为光学成像系统成像面上电子感光元件有效像素区域对角线长的一半，TTL为第一透镜物侧面至光学成像系统成像面于光轴上的距离。
当TTL/Imgh满足以上关系式时，才能同时兼顾小型化及高清晰拍摄。如果TTL/Imgh>1.5,则实现小型化的同时无法保证高清晰成像效果。
根据本公开的一些实施例，所述光学成像系统满足下列关系式：1.0<TTL/f<2.0；其中，f为所述光学成像系统的有效焦距，TTL为第一透镜物侧面至光学成像系统成像面于光轴上的距离。
当TTL/f满足该上述关系式时，不仅能实现光学镜头小型化，同时能保证光线更好的汇聚于成像面上。如果TTL/f≤1.0时，透镜组光学长度太短，会造成系统敏感度加大，同时不利于光线在成像面上的汇聚。当TTL/f≥2时，透镜组光学长度太长，会造成光线进入成像面主光线角度太大，系统成像面边缘光线无法成像在感光面上，造成成像信息不全。
根据本公开的一些实施例，所述光学成像系统满足下列关系式：0.6<f/f1<1；其中，f1为第一透镜的光学有效焦距，f为所述光学成像系统的有效焦距。第一透镜提供透镜组由物空间到像空间全部光学信息，第一透镜的口径大小及焦距决定了光学成像系统对物空间光信息的获取。
当f/f1满足该上述关系式时，镜头加工工艺简单，并且由第一透镜产生的像差修正难度适宜， 可以满足拍摄需求。当f/f1≥1时，会造成系统敏感度加大，加工工艺困难，并且由第一透镜产生的像差修正难度加大，难以满足拍摄需求。f/f1≤0.6时，第一透镜与光学系统焦距配比不合适，无法校正由第一透镜所产生的像差。
根据本公开的一些实施例，所述光学成像系统满足下列关系式：-600<(R1+R2)/F1<50；其中，R1为所述第一透镜的物侧面近轴区域曲率半径，R2为第一透镜的像侧面近轴区域曲率半径，f1为所述第一透镜的光学有效焦距。第一透镜提供透镜组由物空间到像空间全部光学信息，且要满足大口径要求。
当(R1+R2)/F1满足该上述关系式时，利于加工，并且有利于光学成像系统对物空间光信息获取，可以取得较好的成像效果。当(R1+R2)/f1≥50时，会加大光学系统敏感度，不利于加工；(R1+R2)/f1≤-600时，不利于光学系统对物空间光信息获取，成像效果无法达到设计预想要求。
根据本公开的一些实施例，所述光学成像系统满足下列关系式：-0.3<R5/R6<-0.2；其中，R5为第三透镜物侧面近轴区域曲率半径，R6为第三透镜像侧面近轴区域曲率半径。
当R5/R6满足上述关系式时，第三透镜物侧面近轴区域曲率半径和像侧面近轴区域曲率半径较为合适，可合理的增大入射角以满足光学成像系统像高要求，同时降低系统敏感性，提高组装稳定性。
根据本公开的一些实施例，所述光学成像系统满足下列关系式：-1.8<f3/f<-1；其中，f3为所述第三透镜的光学有效焦距，f为所述光学成像系统的有效焦距。
当f3/f满足上述关系式时，第三透镜的焦距与系统焦距配比可有效的降低系统总长，有利于光线在成像面上的汇聚。当f3/f≤-1.8时，致使系统总长过大，组装敏感性增大。当f3/f≥-1时，可导致镜头杂散光增多，影响成像质量。
根据本公开的一些实施例，所述光学成像系统满足下列关系式：1<(R7*R8)/(R7+R8)<3；其中，R7为所述第四透镜的物侧面近轴区域曲率半径，R8为所述第四透镜的像侧面近轴区域曲率半径。
当(R7*R8)/(R7+R8)满足上述关系式时，第四透镜物侧面近轴区域曲率半径和像侧面近轴区域曲率半径较为合适，可合理修正光学成像系统的球差，改善歪曲像差，像散，同时降低系统敏感性，提高组装稳定性。
根据本公开的一些实施例，所述光学成像系统满足下列关系式：Fno＜2；Fno为光学透镜组光圈数。
当Fno满足上述关系式时，可以让光学成像系统有足够的进光量，可以使电子设备能够拍摄高质量夜景、星空等光亮度不大的物空间场景。
根据本公开第二方面实施例的取像装置，包括：所述的光学成像系统和电子感光元件，所述电子感应元件设置于所述光学成像系统的像侧。
根据本公开第三方面实施例的电子设备，包括：外壳和取像装置，所述外壳设置有安装孔，所述取像装置设置于所述外壳且可获取图像。

具体实施方式
下面详细描述本公开的实施例，参考附图描述的实施例是示例性的，下面详细描述本公开的实施例。
下面参考图1-图28描述根据本公开实施例的光学成像系统。
如图1所示，本实用新型的实施方式提供了一种光学成像系统，包括：第一透镜L1、第二透镜L2、第三透镜L3、第四透镜L4、第五透镜L5和第六透镜L6，该六个透镜从物侧至像侧依次排布。
第一透镜L1具有正曲折力，第一透镜L1的物侧面S1近轴区域为凸面，其像侧面S2近轴区域为凸面或凹面。第二透镜L2具有正曲折力，第二透镜L2的物侧面S3近轴区域为凹面，而且第二透镜L2的像侧面S4近轴区域为凸面。第三透镜L3具有负曲折力，第三透镜L3的物侧面S5近轴区域为凸面，而且第三透镜L3的像侧面S6近轴区域为凹面。第四透镜L4具有负曲折力，第四透镜L4的物侧面S7近轴区域为凹面，而且第四透镜L4的像侧面S8近轴区域为凹面或凸面。第五透镜L5具有正曲折力，第五透镜L5的物侧面S9近轴区域为凸面，而且第五透镜L5的像侧面S10近轴区域为凹面或凸面。第六透镜L6具有负曲折力,第六透镜L6的物侧面S11近轴区域为凹面或凸面，像侧面S12近轴区域为凹面。
光学成像系统满足关系式：Fno/TTL<0.4，以及0.2<GTL6/ITL6<0.3。其中，Fno为光学透镜组光圈数，TTL为第一透镜L1的物侧面S1至成像面S15于光轴上的距离，GTL6为第六透镜L6的物侧面S11到像侧面S12平行于光轴处最短的距离，ITL6为第六透镜L6的物侧面S11到像侧面S12平行于光轴处最长的距离。
具体地，光学成像系统满足关系式：Fno/TTL<0.4，满足该关系式的光学成像系统可同时兼顾镜头系统大光圈及小型化设计要求，为摄像拍摄提供足够的通光量，满足高画质高清晰拍摄需要。因此，只有满足Fno/TTL<0.4才能同时满足大光圈及小型化结构的特点。如果Fno/TTL>0.4,兼顾小型化的同时会造成光学系统通光量不足，拍摄出的画面清晰度下降。
此外，光学成像系统还满足关系式：0.2<GTL6/ITL6<0.3。满足该关系式的该透镜为光轴处超薄设计，这样可有效压缩光学成像系统的总长度，实现超薄的设计理念，但如果中心处太薄，无 法满足生产加工要求，以及无法保证成型良率，因此该透镜最厚处及最薄处应满足一定比例关系才能保证可加工性及成型良率。如果当GTL6/ITL6>0.3，则无法实现超薄设计要求；当GTL6/ITL6<0.2，会导致中心处太薄，无法实现生产加工要求，保证成型良率。
由此，通过同时满足上述两个关系式，本公开的光学成像系统可以兼顾小型化和大通光量，从而可以拍摄出高清晰度的画面，而且还可以进一步地减小总长度，从而可以更好地符合小型化设计理念。
在某些实施方式中，光学成像系统满足下列关系式：1.5<TTL/DL<3.0。其中，TTL为第一透镜L1的物侧面S1至光学成像系统的成像面S15于光轴上的距离，DL为光学成像系统光阑孔径直径大小。
具体地，当TTL/DL满足上述关系式时才能保证镜头小型化设计，并且提供镜头拍摄所需的通光量，从而实现高画质高清晰的拍摄效果。如果当TTL/DL<1.5时，满足小型化设计时通光口径会过大，造成边缘光线进入光学成像系统，降低光学成像系统的成像质量；如果TTL/DL>3，满足小型化的同时，会造成光阑通光口径过小，无法满足光学成像系统的通光量要求，实现不了暗光场景高清晰拍摄要求。
在某些实施方式中，光学成像系统满足下列关系式：0.5<DL/Imgh<0.8。其中，DL为光学成像系统的光阑孔径直径，Imgh为成像面上电子感光元件有效像素区域对角线长的一半。
具体地，光学成像系统光阑孔径直径大小决定了整个光学成像系统通光量大小，感光面尺寸大小决定了整个摄像系统画面清晰度及像素大小，两者合理配合才能保证足够的通光量，保证拍摄图像清晰度。如果DL/Imgh>0.8,则会造成光学成像系统曝光过大，光亮度太高，影响电子设备的画面质量；如果DL/Imgh<0.5,则会造成光学成像系统的通光量不足，光线相对亮度不够时会造成电子设备的画面清晰度下降。
在某些实施方式中，光学成像系统满足下列关系式：TTL/Imgh<1.5。其中，Imgh为成像面上电子感光元件有效像素区域对角线长的一半，TTL为第一透镜L1物侧面至光学成像系统成像面于光轴上的距离。
具体地，当TTL/Imgh满足以上关系式时才能同时兼顾小型化及高清晰拍摄，满足以上关系式时才能同时兼顾小型化及高清晰拍摄。如果TTL/Imgh>1.5,则实现小型化的同时无法保证高清晰成像效果，造成电子设备的性能较差。
在某些实施方式中，光学成像系统满足下列关系式：1.0<TTL/f<2.0；其中，f为光学成像系统的有效焦距，TTL为第一透镜L1的物侧面S1至光学成像系统的成像面S15于光轴上的距离。
具体地，当TTL/f满足该上述关系式时，光学成像系统可以合理控制焦距以及光学镜头总长度，不仅能实现光学镜头小型化，同时也能保证光线更好的汇聚于成像面S15上。如果TTL/f≤1.0时，透镜组光学长度太短，会造成系统敏感度加大，同时不利于光线在成像面上的汇聚。当TTL/f≥2时，透镜组光学长度太长，会造成光线进入成像面主光线角度太大，光学成像系统的成像面S15边缘光线无法成像在感光面上，造成成像信息不全。
在某些实施方式中，光学成像系统满足下列关系式：0.6<f/f1<1；其中，f1为第一透镜L1的 光学有效焦距，f为光学成像系统的有效焦距。第一透镜L1提供透镜组由物空间到像空间全部光学信息，第一透镜L1的口径大小及焦距决定了光学成像系统对物空间光信息的获取。
具体地，当f/f1满足该上述关系式时，透镜加工工艺简单，并且由第一透镜L1产生的像差修正难度适宜，可以满足拍摄需求。如果当f/f1≥1时，会造成系统敏感度加大，加工工艺困难，并且由第一透镜L1产生的像差修正难度加大，难以满足用户的拍摄需求；当f/f1≤0.6时，第一透镜L1与光学系统焦距配比不合适，无法校正由第一透镜L1所产生的像差。
在某些实施方式中，光学成像系统满足下列关系式：-600<(R1+R2)/f1<50；其中，R1为第一透镜L1的物侧面S1近轴区域曲率半径，R2为第一透镜L1的像侧面S2近轴区域曲率半径，f1为第一透镜L1的光学有效焦距。第一透镜L1提供透镜组由物空间到像空间全部光学信息，且要满足大口径要求。
具体地，当(R1+R2)/f1满足该上述关系式时，利于加工，并且有利于光学成像系统对物空间光信息获取，可以取得较好的成像效果。如果当(R1+R2)/f1≥50时，会加大光学成像系统敏感度，不利于光学成像系统对光信息的加工；当(R1+R2)/f1≤-600时，不利于光学系统对物空间光信息的获取，光学成像系统的成像效果无法达到设计预想要求。
在某些实施方式中，光学成像系统满足下列关系式：-0.3<R5/R6<-0.2；其中，R5为第三透镜L3的物侧面S5近轴区域曲率半径，R6为第三透镜L3的像侧面S6近轴区域曲率半径。
具体地，当R5/R6满足上述关系式时，第三透镜L3的物侧面S5近轴区域曲率半径和像侧面S6近轴区域曲率半径较为合适，可合理的增大入射角以满足光学成像系统像高要求，同时降低系统敏感性，提高组装稳定性。
在某些实施方式中，光学成像系统满足下列关系式：-1.8<f3/f<-1；其中，f3为第三透镜L3的的光学有效焦距，f为光学成像系统的有效焦距。
具体地，当f3/f满足上述关系式时，第三透镜L3的的焦距与系统焦距配比可有效的降低系统总长，有利于光线在成像面上的汇聚。如果当f3/f≤-1.8时，致使光学成像系统总长过大，组装敏感性增大；当f3/f≥-1时，可导致镜头杂散光增多，影响光学成像系统的成像质量。
在某些实施方式中，光学成像系统满足下列关系式：1<(R7*R8)/(R7+R8)<3；其中，R7为第四透镜L4的物侧面S7近轴区域曲率半径，R8为第四透镜L4的像侧面S8近轴区域曲率半径。
具体地，当(R7*R8)/(R7+R8)满足上述关系式时，第四透镜L4的物侧面S7近轴区域曲率半径和像侧面S8近轴区域曲率半径较为合适，可合理修正光学成像系统的球差，改善歪曲像差，像散，同时降低系统敏感性，提高组装稳定性。
在某些实施方式中，光学成像系统满足下列关系式：Fno＜2；Fno为光学透镜组光圈数。
具体地，当Fno满足上述关系式时，可以让光学成像系统有足够的进光量，达到拍摄高质量夜景、星空等光亮度不大的物空间场景。
