具体实施方式detailed description

在开始详细描述本发明之前，首先要说明的是，在本发明附图中，类似的组件是以相同的编号来表示。其中，本篇说明书所言的「一透镜具有正屈光率(或负屈光率)」，是指所述透镜在光轴附近区域具有正屈光率(或负屈光率)而言。「一透镜的物侧面(或像侧面)具有位于某区域的凸面部(或凹面部)」，是指该区域相较于径向上紧邻该区域的外侧区域，朝平行于光轴的方向更为「向外凸起」(或「向内凹陷」)而言。以图15为例，其中I为光轴且此一透镜是以该光轴I为对称轴径向地相互对称，该透镜的物侧面于A区域具有凸面部、B区域具有凹面部而C区域具有凸面部，原因在于A区域相较于径向上紧邻该区域的外侧区域(即B区域)，朝平行于光轴的方向更为向外凸起，B区域则相较于C区域更为向内凹陷，而C区域相较于E区域也同理地更为向外凸起。「圆周附近区域」，是指位于透镜上仅供成像光线通过的曲面的圆周附近区域，亦即图中的C区域，其中，成像光线包括了主光线Lc(chief ray)及边缘光线Lm(marginal ray)。「光轴附近区域」是指该仅供成像光线通过的曲面的光轴附近区域，亦即图15中的A区域。此外，各透镜还包含一延伸部E，用以供该透镜组装于光学成像镜头内，理想的成像光线并不会通过该延伸部E，但该延伸部E的结构与形状并不限于此，以下的实施例为求附图简洁均省略了延伸部。Before starting to describe the present invention in detail, it should first be noted that in the drawings of the present invention, similar components are denoted by the same numerals. Wherein, "a lens has positive refractive power (or negative refractive power)" mentioned in this specification means that the lens has positive refractive power (or negative refractive power) in the vicinity of the optical axis. "The object side (or image side) of a lens has a convex surface (or concave surface) located in a certain area" means that the area is closer to the direction parallel to the optical axis than the area immediately outside the area in the radial direction. "Outwardly convex" (or "inwardly concave"). Take Figure 15 as an example, where I is the optical axis and the lens is radially symmetrical to each other with the optical axis I as the axis of symmetry, the object side of the lens has a convex surface in the A region, a concave surface in the B region, and a C region. The reason is that the A region is more convex in the direction parallel to the optical axis than the radially outer region (ie, the B region) of the region, and the B region is more convex than the C region. Concave inwardly, and area C is more outwardly convex than area E similarly. "Area near the circumference" refers to the area near the circumference of the curved surface on the lens through which only the imaging light passes, that is, the area C in the figure, where the imaging light includes the chief ray Lc (chief ray) and the marginal ray Lm (marginal ray). The "region near the optical axis" refers to the region near the optical axis of the curved surface through which only the imaging light passes, that is, the region A in FIG. 15 . In addition, each lens also includes an extension part E for the lens to be assembled in the optical imaging lens. The ideal imaging light does not pass through the extension part E, but the structure and shape of the extension part E are not limited thereto. In the following embodiments, extension parts are omitted for simplicity of the drawings.

如图1所示，本发明光学成像镜头1，从放置物体(图未示)的物侧2至成像的像侧3，沿着光轴(optical axis)4，依序包含有一光圈、第一透镜10、第二透镜20、第三透镜30、第四透镜40、第五透镜50、第六透镜60，滤光片72及成像面(image plane)71。一般说来，第一透镜10、第二透镜20、第三透镜30、第四透镜40、第五透镜50与第六透镜60都可以是由透明的塑料材质所制成，但本发明不以此为限。在本发明光学成像镜头1中，具有屈光率的镜片总共只有六片。光轴4为整个光学成像镜头1的光轴，所以每个透镜的光轴和光学成像镜头1的光轴都是相同的。As shown in FIG. 1 , the optical imaging lens 1 of the present invention includes a diaphragm, a first A lens 10 , a second lens 20 , a third lens 30 , a fourth lens 40 , a fifth lens 50 , a sixth lens 60 , a filter 72 and an image plane 71 . Generally speaking, the first lens 10, the second lens 20, the third lens 30, the fourth lens 40, the fifth lens 50 and the sixth lens 60 can all be made of transparent plastic material, but the present invention does not rely on This is the limit. In the optical imaging lens 1 of the present invention, there are only six lenses with refractive power. The optical axis 4 is the optical axis of the entire optical imaging lens 1 , so the optical axis of each lens is the same as the optical axis of the optical imaging lens 1 .

此外，光学成像镜头1还包含光圈(aperture stop)80，而设置于适当的位置。在图1中，光圈80是设置在物侧2与第一透镜10之间。当由位于物侧2的待拍摄物(图未示)所发出的光线(图未示)进入本发明光学成像镜头1时，即会经由光圈80、第一透镜10、第二透镜20、第三透镜30、第四透镜40、第五透镜50、第六透镜60与滤光片72之后，会在像侧3的成像面71上聚焦而形成清晰的影像。In addition, the optical imaging lens 1 also includes an aperture stop 80 disposed at a proper position. In FIG. 1 , the aperture 80 is disposed between the object side 2 and the first lens 10 . When the light (not shown) emitted by the object to be photographed (not shown) on the object side 2 enters the optical imaging lens 1 of the present invention, it will pass through the aperture 80, the first lens 10, the second lens 20, the second lens After the three lenses 30 , the fourth lens 40 , the fifth lens 50 , the sixth lens 60 and the filter 72 , they will focus on the imaging surface 71 of the image side 3 to form a clear image.

在本发明各实施例中，选择性设置的滤光片72还可以是具各种合适功能的滤镜，可滤除特定波长的光线(例如红外线)，置于第六透镜60与成像面71之间。滤光片72的材质为玻璃。In each embodiment of the present invention, the optional filter 72 can also be a filter with various suitable functions, which can filter out light of a specific wavelength (such as infrared rays), and is placed between the sixth lens 60 and the imaging surface 71 between. The material of the filter 72 is glass.

本发明光学成像镜头1中的各个透镜，都分别具有朝向物侧2的物侧面，与朝向像侧3的像侧面。另外，本发明光学成像镜头1中的各个透镜，亦都具有接近光轴4的光轴附近区域、与远离光轴4的圆周附近区域。例如，第一透镜10具有第一物侧面11与第一像侧面12；第二透镜20具有第二物侧面21与第二像侧面22；第三透镜30具有第三物侧面31与第三像侧面32；第四透镜40具有第四物侧面41与第四像侧面42；第五透镜50具有第五物侧面51与第五像侧面52；第六透镜60具有第六物侧面61与第六像侧面62。Each lens in the optical imaging lens 1 of the present invention has an object side facing the object side 2 and an image side facing the image side 3 respectively. In addition, each lens in the optical imaging lens 1 of the present invention also has an area near the optical axis close to the optical axis 4 and an area near the circumference far away from the optical axis 4 . For example, the first lens 10 has a first object side 11 and a first image side 12; the second lens 20 has a second object side 21 and a second image side 22; the third lens 30 has a third object side 31 and a third image Side 32; the fourth lens 40 has a fourth object side 41 and a fourth image side 42; the fifth lens 50 has a fifth object side 51 and a fifth image side 52; the sixth lens 60 has a sixth object side 61 and a sixth Like side 62.

本发明光学成像镜头1中的各个透镜，还都分别具有位在光轴4上的中心厚度T。例如，第一透镜10具有第一透镜厚度T1、第二透镜20具有第二透镜厚度T2、第三透镜30具有第三透镜厚度T3、第四透镜40具有第四透镜厚度T4，第五透镜50具有第五透镜厚度T5，第六透镜60具有第六透镜厚度T6。所以，在光轴4上光学成像镜头1中透镜的中心厚度总合称为ALT。亦即，ALT＝T1+T2+T3+T4+T5+T6。Each lens in the optical imaging lens 1 of the present invention also has a central thickness T on the optical axis 4 . For example, the first lens 10 has a first lens thickness T1, the second lens 20 has a second lens thickness T2, the third lens 30 has a third lens thickness T3, the fourth lens 40 has a fourth lens thickness T4, and the fifth lens 50 Having a fifth lens thickness T5, the sixth lens 60 has a sixth lens thickness T6. Therefore, the central thickness of the lens in the optical imaging lens 1 on the optical axis 4 is collectively referred to as ALT. That is, ALT=T1+T2+T3+T4+T5+T6.

另外，本发明光学成像镜头1中在各个透镜之间又具有位在光轴4上的空气间隙(air gap)。例如，第一透镜10到第二透镜20之间空气间隙宽度AG12、第二透镜20到第三透镜30之间空气间隙宽度AG23、第三透镜30到第四透镜40之间空气间隙宽度AG34、第四透镜40到第五透镜50之间空气间隙宽度AG45、第五透镜50到第六透镜60之间空气间隙宽度AG56。所以，第一透镜10到第六透镜50之间位于光轴4上各透镜间的五个空气间隙宽度的总合即称为AAG。亦即，AAG＝AG12+AG23+AG34+AG45+AG56。In addition, the optical imaging lens 1 of the present invention has an air gap on the optical axis 4 between each lens. For example, the air gap width AG12 between the first lens 10 and the second lens 20, the air gap width AG23 between the second lens 20 and the third lens 30, the air gap width AG34 between the third lens 30 and the fourth lens 40, The width of the air gap between the fourth lens 40 and the fifth lens 50 is AG45 , and the width of the air gap between the fifth lens 50 and the sixth lens 60 is AG56 . Therefore, the sum of the widths of the five air gaps between the first lens 10 to the sixth lens 50 between the lenses on the optical axis 4 is called AAG. That is, AAG=AG12+AG23+AG34+AG45+AG56.

Please refer to FIG. 16 , which is a first preferred embodiment of an electronic device 100 using the aforementioned optical imaging lens 1 . The electronic device 100 includes a casing 110 and an image module 120 installed in the casing 110 . FIG. 16 only takes a mobile phone as an example to illustrate the electronic device 100, but the type of the electronic device 100 is not limited thereto.

FIG. 16 illustrates the optical imaging lens 1 of the aforementioned first embodiment. In addition, the electronic device 100 further includes a lens barrel 130 for the optical imaging lens 1, a module housing unit (module housing unit) 140 for the lens barrel 130, and a substrate for the module housing unit 140. 172 , and the image sensor 70 disposed on the substrate 172 and located on the image side 3 of the optical imaging lens 1 . The image sensor 70 in the optical imaging lens 1 may be an electronic photosensitive component, such as a photosensitive coupling component or a complementary metal oxide semiconductor component. The imaging surface 71 is formed on the image sensor 70 .

本发明所使用的影像传感器70是采用板上连接式芯片封装的封装方式而直接连接在基板172上。这和传统芯片尺寸封装的封装方式的差别在于，板上连接式芯片封装不需使用保护玻璃。因此，在光学成像镜头1中并不需要在影像传感器70之前设置保护玻璃，然本发明并不以此为限。The image sensor 70 used in the present invention is directly connected to the substrate 172 in a chip-on-board package. The difference between this and the traditional chip-scale package packaging method is that the board-attached chip package does not need to use a protective glass.

Secondly, the image sensor 70 used in this embodiment is directly connected to the substrate 172 in a chip on board (COB) package, but the present invention is not limited thereto.

The module back unit 140 has a lens back seat 141 and an image sensor back seat 146 disposed between the lens back seat 141 and the image sensor 70 , but in other implementations, the image sensor back seat 146 does not necessarily exist. The lens barrel 130 is disposed coaxially with the lens rear seat 141 along the axis II′, and the lens barrel 130 is disposed inside the lens rear seat 141 .

另请参阅图17，为应用前述光学成像镜头1的可携式电子装置200的第二较佳实施例。第二较佳实施例的可携式电子装置200与第一较佳实施例的可携式电子装置100的主要差别在于：镜头后座141具有第一座体142、第二座体143、线圈144及磁性组件145。第一座体142供镜筒130设置并与镜筒130外侧相贴合且沿轴线I-I'设置、第二座体143沿轴线I-I'并环绕着第一座体142的外侧设置。线圈144设置在第一座体142的外侧与第二座体143的内侧之间。磁性组件145设置在线圈144的外侧与第二座体143的内侧之间。Please also refer to FIG. 17 , which is a second preferred embodiment of a portable electronic device 200 using the aforementioned optical imaging lens 1 . The main difference between the portable electronic device 200 of the second preferred embodiment and the portable electronic device 100 of the first preferred embodiment is that the lens rear seat 141 has a first seat body 142, a second seat body 143, a coil 144 and magnetic assembly 145. The first seat 142 is provided for the lens barrel 130 and fits on the outside of the lens barrel 130 and is arranged along the axis II'; the second seat 143 is arranged along the axis II' and surrounds the outside of the first seat 142 . The coil 144 is disposed between the outer side of the first base body 142 and the inner side of the second base body 143 . The magnetic component 145 is disposed between the outer side of the coil 144 and the inner side of the second seat 143 .

第一座体142可带着镜筒130及设置在镜筒130内的光学成像镜头1沿轴线I-I'，即图1的光轴4移动。影像传感器后座146则与第二座体143相贴合。滤光片72，则是设置在影像传感器后座146。第二实施例可携式电子装置200的其他组件结构则与第一实施例的可携式电子装置100类似，故在此不再赘述。The first seat 142 can move along the axis II′, that is, the optical axis 4 in FIG. 1 , with the lens barrel 130 and the optical imaging lens 1 disposed in the lens barrel 130 . The image sensor rear seat 146 is attached to the second seat body 143 . The filter 72 is disposed on the rear seat 146 of the image sensor. The structure of other components of the portable electronic device 200 of the second embodiment is similar to that of the portable electronic device 100 of the first embodiment, so details will not be repeated here.
