需要说明的是,当元件被称为“固定于”另一个元件,它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件,它可以是直接连接到另一个元件或者可能同时存在居中元件。本文所使用的术语“内”、“外”、“左”、“右”以及类似的表述只是为了说明的目的,并不表示是唯一的实施方式。
参考图1,本申请一实施例提供一种光学***100,光学***100由物侧至像侧依次包括具有正屈折力的第一透镜L1、具有负屈折力的第二透镜L2、具有负屈折力的第三透镜L3、具有负屈折力的第四透镜L4、具有负屈折力的第五透镜L5以及具有正屈折力的第六透镜L6。
第一透镜L1包括物侧面S1及像侧面S2,第二透镜L2包括物侧面S3及像侧面S4,第三透镜L3包括物侧面S5及像侧面S6,第四透镜L4包括物侧面S7及像侧面S8,第五透镜L5包括物侧面S9及像侧面S10,第六透镜L6包括物侧面S11及像侧面S12,光学***100还包括位于第六透镜L6像侧的成像面S15,成像面S15可以为感光元件的感光表面。
第一透镜L1的物侧面S1和像侧面S2均为凸面,第二透镜L2的物侧面S3和像侧面S4均为凹面。
在上述光学***100中,第一透镜L1能够为光学***100提供正屈折力,以缩短光学***100的光学总长,且由于第一透镜L1的物侧面S1为凸面,因此能够加强第一透镜L1的正屈折力,使光学***100的光学总长进一步缩短,有利于实现小型化设计。第二透镜L2为光学***100提供负屈折力,以平衡第一透镜L1所产生的色差及球差,从而使光学***100能够校正轴上色差及球差。同时,由于第二透镜L2的像侧面S4为凹面,从而还能够防止过度校正球差。第四透镜L4为光学***100提供负屈折力,从而能够良好地校正场曲。另外,第六透镜L6为光学***100提供正屈折力,且对光学***100进行最后的校正,同时配合物侧的各透镜,以形成具备远摄效果的光学***100。
在一些实施例中,第六透镜L6的物侧面S11为凸面,此时,可进一步加强第六透镜L6的正屈折力,从而对物侧多片具有负屈折力的透镜(第二透镜L2、第三透镜L3、第四透镜L4及第五透镜L5)所产生的像差进行有效矫正。
在一些实施例中,光学***100包括孔径光阑,孔径光阑为独立于各透镜的元件,孔径光阑可以设置于第一透镜L1的物侧,或第一透镜L1与第六透镜L6之间。在另一些实施例中,孔径光阑也可位于第一透镜L1至第六透镜L6中任一透镜的表面上(如物侧面或像侧面),与透镜形成作用关系,例如,通过在透镜的表面涂覆阻光涂层以在该表面形成孔径光阑;或通过夹持件固定夹持透镜的表面,位于该表面的夹持件结构能够限制轴上物点成像光束的宽度,从而在该表面上形成孔径光阑。优选的,孔径光阑位于第二透镜L2的物侧面S3上。
在一些实施例中,光学***100中各透镜的物侧面和像侧面均为非球面,非球面结构的采用能够提高透镜设计的灵活性,并有效地校正球差,改善成像质量。在另一些实施例中,光学***100中各透镜的物侧面和像侧面也可以均为球面。需要注意的是,上述实施例仅是对本申请的一些实施例的举例,在一些实施例中,光学***100中任一透镜的表面可以是非球面或球面。
在一些实施例中,第六透镜L6的像侧面S12存在至少一个反曲点,具体的,其中一个实施例中的第六透镜L6的像侧面S12由光轴处至边缘处的面型依次呈凸面、凹面及凸 面。当透镜的表面为非球面时,可参考非球面公式:
其中,Z为非球面上任一点与表面顶点的纵向距离,r为非球面上任一点到光轴的距离,c为顶点曲率(曲率半径的倒数),k为圆锥常数,A、B、C、D、E、F、G…为非球面系数。
在一些实施例中,光学***100中的各透镜的材质可以均为玻璃或均为塑料,塑料材质的透镜能够减少光学***100的重量并降低生产成本,而玻璃材质的透镜使光学***100具备优良的光学性能以及较高的耐温的特性。需要注意的是,光学***100中各透镜的材质也可以玻璃和塑料的任意组合,并不一定要是均为玻璃或均为塑料。在一些实施例中,第一透镜L1的材质为玻璃,而光学***100中其他透镜的材质为塑料,从而光学***100能够耐受物侧较高的温度,同时还能保持较低的生产成本。
在一些实施例中,光学***100还包括红外截止滤光片L7,红外截止滤光片L7设置于第六透镜L6与成像面S15之间,红外截止滤光片L7包括物侧面S13及像侧面S14。红外截止滤光片L7能够滤除红外光,防止红外光到达成像面S15而对感光元件造成成像干扰。
在一些实施例中,光学***100满足关系:2.0≤FNO≤10.0;FNO为光学***100的光圈数。FNO可以为2.95、2.96或2.97。
在一些实施例中,光学***100满足关系:0.75≤TTL/f≤1.25;TTL为光学***100的光学总长,即第一透镜L1的物侧面S1至光学***100的成像面S15于光轴上的距离,f为光学***100的有效焦距。TTL/f可以为0.81、0.82、0.83或0.84。在满足上述关系的条件下,当光学***100的光学总长保持不变时,上述关系式的数值越小则光学***100的有效焦距越长,视场角减小,从而光学***100具备远摄特性;在满足上述关系的条件下,当光学***100的光学总长保持不变时,上述关系式的数值越大则光学***100的有效焦距越短,视场角增大,从而光学***100具备广角特性。另外,当低于下限时,会导致像侧透镜***的焦度变小从而容易产生倍率色像差,图像的分辨率降低。高于上限时,则会导致光学***100的整体尺寸变大,光学***100的总长和其中的透镜的半径也会过大。因此,满足上述关系时,能够得到高分辨率的图像,并使光学***100更为紧凑。
在一些实施例中,光学***100满足关系:0.51≤TLENS/TTL≤0.71;TLENS为第一透镜L1的物侧面S1至第六透镜L6的像侧面S12于光轴上的距离,TTL为光学***100的光学总长。TLENS/TTL可以为0.597、0.600、0.605、0.610、0.615、0.620或0.625。满足上述关系时,比值越小,则光学***100于光轴方向的尺寸缩小,且装载光学***100的镜筒的长度也会缩短,从而有利于镜筒的成型;比值越大,则有利于降低光学***100的设计难度。当TLENS/TTL>0.71时,光学***100的光学后焦较短,不利于组装;当TLENS/TTL<0.51时,透镜之间的排布过于紧凑而不利于光学***100的设计,同时降低整个***的光学性能。
在一些实施例中,光学***100满足关系:0.16≤f1/f≤0.59;f1为第一透镜L1的焦距,f为光学***100的有效焦距。f1/f可以为0.367、0.370、0.372、0.377、0.379、0.381、0.383或0.384。满足上述关系式时,第一透镜L1具有合适的焦距,有利于光学***100的屈折力分配及优化,进而使光学***100具有理想的光学性能。
在一些实施例中,当光学***100与感光元件装配成摄像模组,摄像模组满足关系:1≤TTL/IMA≤3;TTL为光学***100的光学总长,IMA为感光元件的有效像素区域的对角距离。TTL/IMA可以为2.02、2.03、2.05、2.08、2.10、2.11或2.12。在满足上述关系的条件下,当光学***100的光学总长确定时,感光元件的有效像素区域的对角距离越大 则光学***100越具备广角特性,感光元件的有效像素区域的对角距离越小则越具备远摄特性。当感光元件的有效像素区域的对角距离变为原来的两倍时,光学***100的尺寸也可同步放大成原来的两倍,此时的光圈数及视场角保持不变。满足上述关系时还有利于感光元件接收完整的光信息,同时还有利于摄像模组的小型化设计。

光学***100满足关系:f1/f=0.364;f1为第一透镜L1的焦距,f为光学***100的有效焦距。满足上述关系式时,第一透镜L1具有合适的焦距,有利于光学***100的屈折力分配及优化,进而使光学***100具有理想的光学性能。
