DETAILED DESCRIPTION

An image capturing lens assembly includes, in order from an object side to an image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, and a sixth lens element. The image capturing lens assembly has a total of six lens elements with refractive power.

The first lens element has positive refractive power, so that it provides the image capturing lens assembly with the positive refractive power as it needs to be. The first lens element has an object-side surface being convex in a paraxial region thereof, so that it is favorable for further enhancing the arrangement of the positive refractive power so as to reduce the total track length of the image capturing lens assembly.

The second lens element can have negative refractive power. Therefore, it is favorable for correcting the aberration of the first lens element with positive refractive power. Moreover, the second lens element can have an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof. Therefore, it is favorable for correcting the astigmatism of the image capturing lens assembly.

The third lens element can have positive refractive power. Therefore, it is favorable for balancing the arrangement of the positive refractive powers so as to reduce the sensitivity of the image capturing lens assembly.

The fourth lens element with refractive power has an object-side surface being concave in a paraxial region thereof. Therefore, it is favorable for correcting astigmatism.

The fifth lens element can have negative refractive power and has an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof, wherein the image-side surface of the fifth lens element has at least one convex shape in an off-axis region thereof. Therefore, it is favorable for further correcting the astigmatism and reducing the incident angle of the light projecting onto an image sensor so as to improve the responding efficiency of the image sensor.

The sixth lens element can have negative refractive power, an object-side surface being convex in a paraxial region thereof and an image-side surface being concave in a paraxial region thereof, wherein the image-side surface of the sixth lens element has at least one convex shape in an off-axis region thereof. Therefore, it is favorable for the principal point being positioned away from the image plane so as to reduce the total track length and effectively correct the aberration of the off-axis.

When a focal length of the third lens element is f3, and a focal length of the fourth lens element is f4, the following condition is satisfied: |f3/f4|<0.50. Therefore, it is favorable for reducing the sensitivity of the image capturing lens assembly so as to obtain better image quality.

When an axial distance between the third lens element and the fourth lens element is T34, and a central thickness of the fourth lens element is CT4, the following condition is satisfied: 0.9<T34/CT4. Therefore, it is favorable for assembling the image capturing lens assembly and maintaining a proper total track length thereof. In some embodiments, the following condition is satisfied: 1.25<T34/CT4<2.75.

When a central thickness of the fifth lens element is CT5, and a central thickness of the sixth lens element is CT6, the following condition is satisfied: 1.6<CT6/CT5. Therefore, it is favorable for avoiding the lens elements with an excessively thin thickness or an excessively thick thickness which are easily crackled or deformed during the manufacturing processes. In some embodiments, the following condition is satisfied: 2.0<CT6/CT5<4.0.

When a focal length of the fifth lens element is f5, and a focal length of the sixth lens element is f6, the following condition is satisfied: −0.65<f6/|f5|<0. Therefore, it is favorable for balancing the refractive powers of the fifth lens element and the sixth lens element so as to reduce the back focal length of the image capturing lens assembly. In some embodiments, the following condition is satisfied: −0.50<f6/|f5|<0.

When a curvature radius of the object-side surface of the sixth lens element is R11, and a curvature radius of the image-side surface of the sixth lens element is R12, the following condition is satisfied: 0<(R11+R12)/(R11−R12). Therefore, it is favorable for further correcting the astigmatism and reducing the back focal length thereof.

When a focal length of the image capturing lens assembly is f, the focal length of the third lens element is f3, the focal length of the fourth lens element is f4, and the focal length of the fifth lens element is f5, the following condition is satisfied: 0.20<|f/f3|+|f/f4|+|f/f5|<1.35. Therefore, it is favorable for balancing the arrangement of the refractive powers so as to keep a compact size. In some embodiments, the following condition is satisfied: 0.20<|f/f3|+|f/f4|+|f/f5|<1.0.

When an Abbe number of the first lens element is V1, an Abbe number of the second lens element is V2, and an Abbe number of the fourth lens element is V4, the following condition is satisfied: 0.6<(V2+V4)/V1<1.2. Therefore, it is favorable for effectively correcting the chromatic aberration of the image capturing lens assembly.

When a curvature radius of the object-side surface of the third lens element is R5, and a curvature radius of the image-side surface of the third lens element is R6, the following condition is satisfied: R5/|R6|<1.0. Therefore, it is favorable for correcting the astigmatism and spherical aberration of the image capturing lens assembly.

When the focal length of the image capturing lens assembly is f, the central thickness of the fourth lens element is CT4, the central thickness of the fifth lens element is CT5, and an axial distance between the fourth lens element and the fifth lens element is T45, the following condition is satisfied: 5≦f/(CT4+T45+CT5)<10. Therefore, it is favorable for avoiding the lens elements which are easily crackled or deformed during the manufacturing processes and maintaining a compact size.

According to the image capturing lens assembly of the present disclosure, the lens elements thereof can be made of glass or plastic material. When the lens elements are made of glass material, the distribution of the refractive power of the image capturing lens assembly may be more flexible to design. When the lens elements are made of plastic material, the manufacturing cost can be effectively reduced. Furthermore, surfaces of each lens element can be arranged to be aspheric, since the aspheric surface of the lens element is easy to form a shape other than spherical surface so as to have more controllable variables for eliminating the aberration thereof, and to further decrease the required number of the lens elements. Therefore, the total track length of the image capturing lens assembly can also be reduced.

According to the image capturing lens assembly of the present disclosure, each of an object-side surface and an image-side surface has a paraxial region and an off-axis region. The paraxial region refers to the region of the surface where light rays travel close to the optical axis, and the off-axis region refers to the region of the surface where light rays travel away from the optical axis. Particularly, when the lens element has a convex surface, it indicates that the surface is convex in the paraxial region thereof; when the lens element has a concave surface, it indicates that the surface is concave in the paraxial region thereof.

According to the image capturing lens assembly of the present disclosure, the image capturing lens assembly can include at least one stop, such as an aperture stop, a glare stop or a field stop. Said glare stop or said field stop is for eliminating the stray light and thereby improving the image resolution thereof.

According to the image capturing lens assembly of the present disclosure, an aperture stop can be configured as a front stop or a middle stop. A front stop disposed between an imaged object and the first lens element can provide a longer distance between an exit pupil of the image capturing lens assembly and the image plane and thereby improves the image-sensing efficiency of an image sensor. A middle stop disposed between the first lens element and the image plane is favorable for enlarging the field of view of the image capturing lens assembly and thereby provides a wider field of view for the same.

The present image capturing lens assembly can be optionally applied to moving focus optical systems. According to the image capturing lens assembly of the present disclosure, the image capturing lens assembly is featured with good correction ability and high image quality, and can be applied to 3D (three-dimensional) image capturing applications, in products such as digital cameras, mobile devices, digital tablets, wearable devices and other mobile terminals.

According to the present disclosure, an image capturing device is provided. The image capturing device includes the image capturing lens assembly according to the aforementioned image capturing lens assembly of the present disclosure, and an image sensor, wherein the image sensor is disposed on an image plane of the aforementioned image capturing lens assembly. In some embodiments, the image capturing device can further include a barrel member, a holding member or a combination thereof.

In FIG. 17, FIG. 18 and FIG. 19, an imaging device 10 may be installed in but not limited to a mobile terminal, including a smart phone (FIG. 17), a tablet personal computer (FIG. 18) or a wearable device (FIG. 19).
