As the advanced semiconductor manufacturing technologies have allowed the pixel size of sensors to be reduced and compact optical systems have gradually evolved toward the field of higher megapixels, there is an increasing demand for compact optical systems featuring better image quality.
A conventional optical system employed in a portable electronic product mainly adopts a four-element lens structure or a five-element lens structure. Due to the popularity of mobile products with high-end specifications, such as smart phones and tablet personal computers, the requirements for high resolution and image quality of present compact optical systems increase significantly. However, the conventional optical systems cannot satisfy these requirements of the compact optical systems.
Other conventional compact optical systems with six-element lens structure enhance image quality and resolution. However, the system cannot correct various aberrations of the system effectively due to the insufficient symmetry of the refractive power and the surface shapes of the first lens element and the sixth lens element of the system which thereby causes worse image quality. Moreover, the total track length cannot be reduced so as to restrict the application on the compact electronic device.

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, wherein the image capturing lens assembly has a total of six lens element with refractive power. The image capturing lens assembly further includes a stop, such as an aperture stop, which is located between an object and the third lens element.
An air distance is between two adjacent surfaces of any two adjacent lens elements, that is, each of the first through sixth lens elements of the image capturing lens assembly is a single and non-cemented lens element. Moreover, the manufacturing process of the cemented lenses is more complex than the non-cemented lenses. In particular, an image-side surface of one lens and an object-side surface of the following lens need to have accurate curvature to ensure these two lens elements will be highly cemented. However, during the cementing process, those two lens elements might not be highly cemented due to displacement and it is thereby not favorable for the image quality of the image capturing lens assembly. Therefore, each of the six lens elements of the image capturing lens assembly is separated from each other in the present disclosure for improving the problem generated by the cemented lens elements.
The first lens element with positive refractive power has an object-side surface being convex in a paraxial region thereof. Therefore, the positive refractive power of the first lens element is adjusted for reducing the total track length of the image capturing lens assembly.
The second lens element with negative refractive power can have an image-side surface being concave in a paraxial region thereof, so that the aberration generated from the first lens element with positive refractive power can be corrected.
The third lens element can have positive refractive power, and can have an object-side surface being concave in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof, that is, the third lens element is meniscus in the paraxial region thereof. Therefore, the excessive spherical aberration can be avoided, and the astigmatism can be reduced effectively.
The fourth lens element can have an object-side surface being concave in a paraxial region thereof and an image-side surface being convex in a paraxial region thereof, that is, the fourth lens element is meniscus in the paraxial region thereof. Therefore, the astigmatism can be corrected effectively.
The fifth lens element can have negative refractive power, and 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, that is, the fifth lens element is meniscus in the paraxial region thereof. Therefore, the Petzval Sum of the image capturing lens assembly can be corrected for obtaining a sharper image. Furthermore, at least one of the object-side surface and the image-side surface of the fifth lens element has at least one inflection point thereon, so that the incident angle of the off-axis on the image plane can be reduced so as to increase the responding efficiency of an image sensor.
The sixth lens element with positive refractive power can have an object-side surface being convex in a paraxial region thereof, and has an image-side surface being convex in a paraxial region thereof. Therefore the characteristic of the symmetry of the image capturing lens assembly can be obtained by the cooperation of the sixth lens element and the convex object-side surface of the first lens element with positive refractive power for controlling the various aberrations, and the compact size of the image capturing lens assembly can also be obtained.
When a focal length of the first lens element is f1, and a focal length of the sixth lens element is f6, the following condition is satisfied: 0<f1/f6<0.9. Therefore, the various aberrations of the image capturing lens assembly can be controlled and the total track length thereof can be reduced by the combination of the sixth lens element with positive refractive power and the first lens element with positive refractive power. Preferably, the following condition is satisfied: 0<f1/f6<0.5.
When a central thickness of the first lens element is CT1, a central thickness of the second lens element is CT2, a central thickness of the third lens element is CT3, a central thickness of the fourth lens element is CT4, a central thickness of the fifth lens element is CT5, a central thickness of the sixth lens element is CT6, and an axial distance between the object-side surface of the first lens element and the image-side surface of the sixth lens element is TD, and the following condition is satisfied: 0.55<(CT1+CT2+CT3+CT4+CT5+CT6)/TD<0.90. Therefore, it is favorable for manufacturing the lens elements so as to obtain the compact size of the image capturing lens assembly.
When a curvature radius of the image-side surface of the fifth lens element is R10, and a curvature radius of the object-side surface of the sixth lens element is R11, the following condition is satisfied: −0.3<R10/R11<0.5. Therefore, the astigmatism can be corrected effectively.
When a focal length of the image capturing lens assembly is f, and a curvature radius of the image-side surface of the sixth lens element is R12, the following condition is satisfied: −10<(f/R12)×10<0. Therefore, the characteristic of the symmetry of the image capturing lens assembly can be obtained for controlling the various aberrations.
A stop can also be placed between the object and the first lens element, wherein when an axial distance between the stop and the image plane is SL, and an axial distance between the object-side surface of the first lens element and the image plane is TL, the following condition is satisfied: 0.80<SL/TL<1.20. Therefore, the total track length can be reduced so as to maintain the compact size of the image capturing lens assembly. Preferably, the following condition is satisfied: 0.93<SL/TL<1.10.
When an axial distance between the fourth lens element and the fifth lens element is T45, and an axial distance between the fifth lens element and the sixth lens element is T56, the following condition is satisfied: 0.03<T45/T56<0.45. Therefore, it is favorable for assembling the lens elements and increasing the yield rate thereof.
When an Abbe number of the second lens element is V2, the following condition is satisfied: V2<25. Therefore, the chromatic aberration of the image capturing lens assembly can be corrected.
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: 0.1<(R5−R6)/(R5+R6)<0.3. Therefore, the spherical aberration can be reduced.
When a vertical distance between a maximum effective semi-diameter position on the object-side surface of the first lens element and an optical axis is SD11, and a vertical distance between a maximum effective semi-diameter position on the image-side surface of the sixth lens element and the optical axis is SD62, the following condition is satisfied: 0.2<SD11/SD62<0.50. Therefore, it is favorable for correcting the aberration of the field of view on the off-axis region.
When an angle between a tangent line extended from a position on the object-side surface of the fifth lens element at a height of one third of the maximum effective semi-diameter and a normal line to an optical axis is ANG51a (wherein when the angle from the normal line to the tangent line is clockwise, ANG51a is positive; and when the angle from the normal line to the tangent line is counterclockwise, ANG51a is negative), and an angle between a tangent line extended from a maximum effective semi-diameter position on the object-side surface of the fifth lens element and a normal line to the optical axis is ANG51b (wherein when the angle from the normal line to the tangent line is clockwise, ANG51b is positive; and when the angle from the normal line to the tangent line is counterclockwise, ANG51b is negative, and |ANG51b|<90 degrees), the following condition is satisfied: −3.0<ANG51a/ANG51b<0. Therefore, the suitable shape of the lens element is favorable for not only the manufacturing and molding of the lens elements, but also obtaining desirable spacing reduction when assembling.
When an axial distance between the first lens element and the second lens element is T12, and an axial distance between the second lens element and the third lens element is T23, the following condition is satisfied: 0.03<T12/723<0.4. Therefore, it is favorable for the assembling of the lens elements and increasing the yield rate.
When an axial distance between the image-side surface of the sixth lens element and an image plane is BL, which is a back focal length, and the axial distance between the object-side surface of the first lens element and the image plane is TL, the following condition is satisfied: 0<BL/TL<0.35. Therefore, the back focal length can be reduced so as to maintain the compact size.
When a curvature radius of an object-side surface of the fourth lens element is R7, and a curvature radius of an image-side surface of the fourth lens element is R8, the following condition is satisfied: −0.6<(R7−R8)/(R7+R8)<0.4. Therefore, the astigmatism can be corrected.
The image capturing lens assembly further includes an image sensor located on the image plane. When a maximum image height of the image capturing lens assembly is ImgH, and the axial distance between the object-side surface of the first lens element and the image plane is TL, the following condition is satisfied: TL/ImgH<2.0. Therefore, the compact size can be maintained for applied to the portable electronic product.
According to the image capturing lens assembly of the present disclosure, the lens elements can be made of plastic or glass material. When the lens elements are made of glass material, the distribution of the refractive power of the image capturing lens assembly can be more flexible to design. When the lens elements are made of plastic material, the manufacturing cost thereof can be reduced. Furthermore, surfaces of each lens element can be arranged to be aspheric to have more controllable variables for correcting the aberration thereof, and to further decrease the required number of the lens elements. Thus, the total track length of the image capturing lens assembly can be effectively reduced.
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 system and an image plane, which improves the image-sensing efficiency of the 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 system and thereby provides a wider field of view for the same.
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 correcting the unexpected light and thereby improving the image quality thereof.
According to the image capturing lens assembly of the present disclosure, when a lens element has a convex surface, it indicates that the surface is convex in a paraxial region thereof; and when a lens element has a concave surface, it indicates that the surface is concave in a paraxial region thereof. Particularly, the paraxial region thereof refers to the region of the surface where light rays travel close to an optical axis and an off-axis region thereof refers to the region of the surface where light rays travel away from the optical axis.
