20 1. PHOTOGRAPHING OPTICAL LENS ASSEMBLY CROSS-REFERENCE TO RELATED APPLICATIONS This non-provisional application claims priority under 35 U.S.C. S119(a) on Patent Application No(s) filed in Taiwan, R.O.C. on Mar. 25, 2011, the entire contents of which are hereby incorporated by reference. BACKGROUND 1. Technical Field The present disclosure relates to an optical lens assembly, and more particularly to a compact optical lens assembly. 2. Related Art In recent years, with the prosperity of photographing opti cal lens assemblies, the demand for compact photographing cameras increases exponentially. The photo-sensing device, e.g. a sensor, of an ordinary photographing camera is com monly selected from a charge coupled device (CCD) and a complementary metal-oxide semiconductor (CMOS) device. In addition, as the advanced semiconductor manufacturing technology enables the miniaturization of pixel size of sen sors, the resolution of a compact optical lens assembly is gradually increased, so that there is an increasing demand for a compact optical lens assembly capable of generating better quality image. A conventional compact photographing lens used in a mobile electronic device usually consists of four lens ele ments, which is disclosed in U.S. Pat. No. 7,365,920. How ever, with the growing popularity of high technology mobile devices including Smart Phone, and PDA (Personal Digital Assistant), the demand for the compact photographing lens with better resolution and image quality increases exponen tially. The conventional four lens assembly does not fulfill the specification of the high-level photographing lens assembly. With the electronic devices heading towards the direction of high functionality while being as Small and light as possible, the inventors recognize that an optical imaging system capable of improving the image quality of mobile electronic devices as well as miniaturizing the overall size of the camera lens equipped therewith is urgently needed.

The differences are described in detail in the following embodiments other than the embodiment described in FIG. 1. Taking FIG. 1A as an example, the photographing optical lens assembly 10 comprises, from an object side to an image side along an optical axis (from left to right in FIG. 1A) in sequence, a first lens element 110, a second lens element 120, a third lens element 130, a fourth lens element 140, a fifth lens element 150, and a sixth lens element 160. The first lens element 110 with positive refractive power provides part of the refractive power needed by the photo graphing optical lens assembly 10, and, therefore, helps reduce the total optical length of the photographing optical lens assembly 10. The first lens element 110 comprises a convex object-side Surface 111 and an image-side Surface 112. When the object-side surface 111 is convex, the positive refractive power of the first lens element 110 is increased which reduces the total optical length of the photographing optical lens assembly 10. The first lens element 110 is made of plastic, and the object-side Surface 111 and the image-side surface 112 are both aspheric. The second lens element 120 with negative refractive power corrects the aberration of the photographing optical lens assembly 10. The second lens element 120 comprises an object-side surface 121 and an image-side surface 122. The second lens element 120 is made of plastic, and the object side surface 121 and the image-side surface 122 are both aspheric. The third lens element 130 with positive refractive power may reduce the sensitivity of the photographing optical lens assembly 10. The third lens element 130 comprises an object side Surface 131 and an image-side Surface 132. The image side surface 132 is concave for correcting the aberration. The third lens element 130 is made of plastic, and both the object side surface 131 and the image-side surface 132 are aspheric. The fourth lens element 140 comprises a concave object side Surface 141 and a convex image-side Surface 142 for correcting the aberration of the photographing optical lens assembly 10. The fourth lens element 140 is made of plastic, and the object-side Surface 141 and the image-side Surface 142 are both aspheric. The fifth lens element 150 comprises a convex object-side surface 151 and a concave image-side surface 152, thereby effectively adjusting the astigmatism of photographing opti cal lens assembly 10. The fifth lens element 150 is made of plastic, and the object-side surface 151 and the image-side surface 152 are both aspheric. In addition, the fifth lens ele ment 150 has at least one inflection point. For example, the fifth lens element 150 has an inflection point 153 for reducing the angle at which the light is projected onto the image plane 150 from the off-axis field and further correcting the off-axis aberrations. The sixth lens element 160 comprises a convex object-side surface 161 and a concave image-side surface 162. When the image-side surface 162 of the sixth element 160 is concave, the principle point is moved toward the object side and, there fore, the total optical length of the photographing optical lens assembly 10 is reduced. When the object-side surface 161 is convex with the image-side surface 162 being concave, the distortion can be corrected. The sixth lens element 160 is made of plastic, and both the object-side surface 161 and the

22 5 image-side Surface 162 are aspheric. In addition, the sixth lens element 160 has at least one inflection point. For example, the sixth lens element 160 has an inflection point 163 that can reduce the angle at which the light is projected onto the image plane 150 from the off-axis field and further correct the off-axis aberrations. In the photographing opticallens assembly 10, the first lens element 110 with positive refractive power provides part of the refractive power needed by the photographing opticallens assembly 10 for reducing the total optical length. When the first lens element 110 has the convex object-side surface 111, the refractive power of the first lens element 110 can be further increased which reduces the total optical length of the photographing opticallens assembly 10. When the fourth lens element 140 has the concave object-side surface 141 and the convex image-side Surface 142, the aberration and chroma tism of the photographing optical lens assembly 10 are cor rected. When the fifth lens element 150 has the convex object side surface 151 and the concave image-side surface 152, the astigmatism of the photographing optical lens assembly 10 can be corrected. When the sixth lens element 160 has the concave image-side Surface 162, the total opticallength of the photographing optical lens assembly 10 can be effectively reduced. When the sixth lens element 160 has the convex object-side Surface 161 and the concave image-side Surface 162, the distortion of the photographing opticallens assembly 10 can be corrected. Furthermore, when the fifth lens element 150 has at least one inflection point 153, the angle at which the light is pro jected onto an image plane 180 from the off-axis field can be reduced to further correct the off-axis aberrations. When the fifth lens element 150 and the sixth lens element 160 are made of plastic, the manufacturing cost can be reduced. The photographing optical lens assembly 10 of the present disclosure satisfies the following condition: -0.3s.(Ro-Ro), (Ro-Ro)-0.6 (condition 1): Wherein R is the curvature radius of the object-side sur face 151; R is the curvature radius of the image-side surface 152. When the photographing opticallens assembly satisfies 10 Condition 1, the object-side surface 151 and the image-side surface 152 have the proper curvature radius which effec tively corrects the high order aberration in the lens assembly. Moreover, the photographing optical lens assembly 10 fur ther comprises an aperture stop 100 disposed in front of the second lens element 120. That is, the aperture stop 100 is on the object side of the second lens element 120. Also, the photographing optical lens assembly 10 comprises an infra red filter 170 and an image sensor 182 disposed on the image plane 180. The photographing optical lens assembly 10 of the present disclosure may further satisfy at least one of the following conditions: 0.8<ff{1.9 (condition 2): O.75<SD/TD<1.10 (condition 3): O.10<BFLATTL3035 (condition 4): 0.1<R/f-0.5 (condition 5): (T23+Ts), Tas1.0 (condition 6): TTL/ImgH-2.5 (condition 7): (condition 8): <(CT+CT)/f-0.19 (condition 9): -0.3<(R7-Rs)/(R,+Rs)<0.5 (condition 10): 23<V-V-40 (condition 11): Wherein SD is the axial distance between the aperture stop 100 and the image-side surface 162; TD is the axial distance between the object-side surface 111 and the image-side sur face 162; BFL is the axial distance between the image-side surface 162 and the image plane 180; TTL is the axial distance between the object-side surface 111 and the image plane 180; R is the curvature radius of the image-side Surface 162; T. is the axial distance between the image-side Surface 122 and the object-side surface 131; T is the axial distance between the image-side surface 132 and the object-side surface 141: Ts is the axial distance between the image-side surface 142 and the object-side surface 151; CT, is the axial distance between the object-side surface 121 and the image-side sur face 122, i.e. the central thickness of the second lens element; CT is the axial distance between the object-side surface 131 and the image-side surface 132, i.e. the central thickness of the third lens element; R, is the curvature radius of the object side surface 141; Rs is the curvature radius of the image-side surface 142: ImgH is half of the diagonal length of the effec tive photosensitive area of the image sensor 182; f is the focal length of the photographing optical lens assembly 10, f is the focal length of the first lens element 110; f, is the focal length of the fourth lens element 140; fs is the focallength of the fifth lens element 150; f is the focal length of the sixth lens element 160; V is the Abbe number of the first lens element 110, and V is the Abbe number of the second lens element 120. When the photographing optical lens assembly 10 satisfies Condition 2, the refractive power of the first lens element 110 is appropriate which helps control the total optical length of the photographing optical lens assembly 10. When the pho tographing optical lens assembly 10 satisfies Condition3, the aperture stop 100 has a proper position that provides the telecentric effect to enhance the image quality. When the photographing optical lens assembly 10 satisfies Condition 4. the back focal length is appropriate so that there is enough room for fabricating and focusing. When the photographing optical lens assembly 10 satisfies Condition 5, the total opti callength of the photographing optical lens assembly 10 can be reduced. When the photographing optical lens assembly 10 satisfies Condition 6, the aberration of the photographing optical lens assembly 10 is corrected. When the photographing optical lens assembly 10 satisfies Condition 7, the photographing optical lens assembly 10 is advantageous in miniaturization. When the photographing optical lens assembly 10 satisfies Condition 8, the refractive power of the fourth lens element 140, the fifth lens element 150, and the sixth lens element 160 are well balanced. The balanced refractive power benefits the correction of aberra tion and the reduction of the optical sensitivity of the photo graphing optical lens assembly 10. When the photographing optical lens assembly 10 satisfies Condition 9, the total opti callength of the photographing optical lens assembly 10 can be reduced. When the photographing optical lens assembly 10 satisfies Condition 10, the object-side surface 141 and the image-side Surface 142 have the proper curvature radius so that the aberration of the photographing optical lens assembly 10 is not excessive. When the photographing optical lens assembly 10 satisfies Condition 11, the chromatism of the photographing optical lens assembly 10 can be corrected. Furthermore, the lenses of the photographing optical lens assembly 10 can be made of glass or plastic. If a lens is made of glass, there is more freedom in distributing the overall refractive power for the photographing optical lens assembly 10. If a lens is made of plastic, the manufacturing cost can be

23 7 reduced. In addition, the surfaces of the lenses can be aspheric. Aspheric profile allows more design parameter free dom for the aberration correction which can reduce the required number of lenses to produce high quality images in the opticallens assembly, so that the total optical length of the photographing opticallens assembly 10 can be reduced effec tively. In the photographing optical lens assembly 10, a convex Surface means the Surface at a paraxial site is convex. A concave Surface means the Surface at a paraxial site is con CaV. Furthermore, at least one stop (such as glare stops, field stops, or other types of stops) may be disposed within the photographing optical lens assembly 10 if necessary for eliminating the stray light, adjusting the field of view, or other improvements concerning the image quality. As for the optical lens assembly 10, the specific schemes are further described with the following embodiments. Parameters in the embodiments are defined as follows. Fno is an f-number value of the photographing optical lens assem bly, and HFOV is a half of maximal field of view in the photographing opticallens assembly 10. The aspheric Surface in the embodiments may be represented by, but not limited to, the following aspheric surface equation (Condition ASP): WhereinY is the distance from the point on the curve of the aspheric Surface to the optical axis, X is the height of a point on the aspheric Surface at a distance Y from the optical axis relative to the tangential plane at the aspheric Surface vertex, k is a conic factor, Ai is an i' order aspheric surface coeffi cient, and in the embodiments, i may be, but is not limited to, 4, 6, 8, 10, 12, 14 and 16.

The sixth lens element 160 with negative refractive power comprises the convex object-side Surface 161, the concave image-side surface 162, and the inflection points 163. The aperture stop 100 can be disposed between the first lens element 110 and the second lens element 120.
