The six lens elements are, in order from an object side to an image side along a light path, 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. Each of the six lens elements has an object-side surface facing the object side and an image-side surface facing the image side.The first lens element may have a positive refractive power. Therefore, it is advantageous to reduce the size of the optical lens assembly for photography at an object end thereof. The object-side surface of the first lens element may be convex in a triaxial portion thereof. Therefore, it is advantageous to reduce the outer diameter of the optical lens assembly for photography at the object end thereof in order to achieve an improved screen-to-housing ratio.The object-side surface of the fourth lens element may be concave in a triaxial portion thereof. Therefore, it is preferable to adjust the surface shape and the refractive power of the fourth lens element so as to correct aberrations, thereby enlarging the image area. The image-side surface of the fourth lens element may be convex in a triaxial portion thereof. Therefore, it is advantageous to merge light to reduce the total track length of the lens.The image-side surface of the fifth lens element is concave in a triaxial portion thereof. Therefore, it is advantageous for the correction of distortions to improve the image quality in the central field of view.The object-side surface of the sixth lens element is convex in a triaxial portion thereof. Therefore, it is advantageous for cooperation with the surface shape of the image-side surface of the sixth lens element to correct curvature of field and astigmatism. The image-side surface of the sixth lens element may be concave in a triaxial portion thereof. Therefore, it is advantageous for the reduction of the back focus width to reduce the lens size.According to the present disclosure, the image-side surface of the fifth lens element may have at least one critical point in an off-axis region thereof. Therefore, it is advantageous for increasing the aspherical surface variation on the image-side surface of the fifth lens element, thereby correcting coma accumulated at the object end of the lens. According to the present disclosure, the object-side surface of the sixth lens element has at least one critical point in an off-axis region thereof. Therefore, it is advantageous for the correction of aberrations such as image distortion, thereby improving image quality. According to the present disclosure, the image-side surface of the sixth lens element may have at least one critical point in an off-axis region thereof. Therefore, it is advantageous for ensuring a certain degree of variation in the overall surface shape of the image-side surface of the sixth lens element, thereby eliminating distortion. See FIG. 33, which shows a schematic view of the critical points C on the image-side surface of the fifth lens element E 5, the object-side surface of the sixth lens element E 6, and the image-side surface of the sixth lens element E 6 according to the first embodiment of the present disclosure.

The fabrication process of cemented lenses is more complex than that of non-cemented lenses, particularly when an image-side surface of one lens element and an object-side surface of the following lens element must have accurate curvatures to ensure that both lenses are properly cemented. Moreover, these two lens elements may not be cemented well during the cementing process due to misalignment, which is disadvantageous for image quality.

See FIG. 34 which shows a schematic view of ET 1 and ET 4 according to the first embodiment of the present disclosure.According to the present disclosure, the foregoing features and conditions may be used in various combinations to achieve respective effects.According to the present disclosure, the lens elements of the optical lens assembly for photography may be made of either glass or plastic material. When the lens elements are made of glass material, the refractive power distribution of the optical lens assembly for photography can be more flexible, and the influence on imaging caused by a change in the ambient temperature can be reduced. The glass lens element may be made either by grinding or by molding. If the lens elements are made of plastic material, the manufacturing cost can be effectively reduced. Moreover, the surfaces of each lens element may be spherical or aspherical. Spherical lens elements are easy to manufacture. The design of aspherical lens elements enables more control variables for eliminating aberrations and for reducing the required number of lens elements, whereby the total track length of the optical lens assembly for photography can be effectively shortened. In addition, the aspherical surfaces can be formed by plastic injection molding or glass casting.According to the present disclosure, when a lens surface is aspherical, it means that the lens surface has an aspherical shape in the entire optically effective area thereof or a part thereof.According to the present disclosure, the material of one or more lens elements may optionally include an additive that generates light absorption and interference effects and changes the transmittance of the lens elements in a particular wavelength range to reduce unwanted stray light or color variations. For example, the additive may optionally filter out light in the wavelength range of 600 nm to 800 nm to reduce excessive red light and / or near infrared light, or optionally filter out light in the wavelength range of 350 nm to 450 nm to prevent excessive blue light and / or near ultraviolet light from disturbing the final image. The additive may be homogeneously mixed with a plastic material used to manufacture a lens element of mixed material by injection molding. Moreover, the additive may be applied to the lens surfaces to achieve the above-mentioned effects.According to the present disclosure, each of the lens-side surface and the image-side surface has a perpendicular region and an off-axis region. The triaxial region refers to the region of the surface in which light rays pass close to the optical axis, and the off-axis region refers to the region of the surface that is away from the multiaxial region. In particular, unless otherwise stated, when the lens element has a convex surface, it means that the surface in the triaxial portion thereof is convex; when the lens element has a concave surface, it means that the surface in the multiaxial portion thereof is concave. Moreover, when a portion of the power or focal point of a lens element is not defined, this means that the portion of the power or focal point of the lens element is in its triaxial region.According to the present disclosure, an inflection point is a point on the surface of the lens element at which the surface changes from concave to convex or vice versa. A critical point is a non-axial point of the lens surface at which its tangent is perpendicular to the optical axis. In this regard, see FIG. 33, which shows a schematic view of inflection points P on the image-side surface of the first lens element E 1, the image-side surface of the second lens element E 2, the object-side surface of the third lens element E 3, the image-side surface of the third lens element E 3, the object-side surface of the fourth lens element E 4, the image-side surface of the fourth lens element E 4, the object-side surface of the fifth lens element E 5, the image-side surface of the fifth lens E 5, the object-side surface of the sixth lens E 6, and the image-side surface of the sixth lens E 6 according to the first embodiment of the present disclosure. The above-mentioned inflection points P on the image-side surface of the first lens element E1, the image-side surface of the second lens element E2, the object-side surface of the third lens element E3, the image-side surface of the third lens element E3, the object-side surface of the fourth lens element E4, the image-side surface of the fourth lens element E4, the object-side surface of the fifth lens element E5, the image-side surface of the fifth lens element E5, the object-side surface of the sixth lens element E6, and the image-side surface of the sixth lens element E6 in FIG. 33 are exemplary. Each of the lens surfaces in various embodiments of the present disclosure may also have one or more inflection points.According to the present disclosure, the image surface of the optical lens assembly for photography based on the corresponding image sensor may be flat or curved, particularly, a curved surface that is concave and faces the object side of the optical lens assembly for photography.According to the present disclosure, an image correction unit such as an image field beam may be optionally disposed between the lens element disposed along the optical path closest to the image side of the optical lens assembly for photography and the image surface to correct aberrations such as curvature of the image field. The optical properties of the image correction unit, such as curvature, thickness, refractive power, position and surface shape (convex or concave surface with spherical, aspherical, diffractive or Fresnel types), can be adjusted according to the construction of the image acquisition unit. In general, a preferred image correction unit is, for example, a thin transparent member having a concave object-side surface and a planar image-side surface, and the thin transparent member is disposed in the vicinity of the image surface.According to the present disclosure, at least one light-redirecting member such as a prism or a mirror, which may have a planar, spherical, aspherical, or free-form surface, may be optionally disposed between an imaged object and the image surface on the imaging radiation path, so that the optical lens assembly for photography may be arranged more flexibly in space and therefore the dimensions of an electronic device are not limited by the total track length of the optical lens assembly for photography. Specifically, see FIGS. 35 and 36, FIG. 35 is a schematic view of a configuration of a light redirecting member in an optical lens assembly for photography according to an embodiment of the present disclosure, and FIG. 36 is a schematic view of another configuration of a light redirecting member in an optical lens assembly for photography according to an embodiment of the present disclosure.

The light-diverting element LF may be disposed between the imaged object and a lens group LG of the optical lens assembly for photography as shown in FIG. 35, or may be disposed between a lens group LG of the optical lens assembly for photography and the image surface IMG as shown in FIG. 36. Also, see FIG. 37 which is a schematic view of a configuration of two light redirecting members in an optical lens assembly for photography according to an embodiment of the present disclosure.

The first light-redirecting element LF 1 is disposed between the imaged object and a lens group LG of the photographing optical lens assembly, the second light-redirecting element LF 2 is disposed between the lens group LG of the photographing optical lens assembly and the image surface IMG, and the propagating direction of the light on the first optical axis OA 1 may be the same direction as the propagating direction of the light on the third optical axis OA 3, as shown in FIG. 37. The optical lens assembly for photography may optionally be provided with three or more light redirecting members, and the present disclosure is not limited to the type, number, and position of the light redirecting members of the embodiments disclosed in the aforementioned figures.According to the present disclosure, the optical lens assembly for photography may include at least one aperture such as an aperture stop, a blend stop, or a field stop. The aperture or the field aperture is adjusted so as to eliminate stray light and thereby improve the image quality.According to the present disclosure, an aperture stop can be configured as a front stop or as a middle stop. A front aperture disposed between an imaged object and the first lens element may provide a greater distance between an exit pupil of the photographing optical lens assembly and the image surface to produce a telecentric effect, thereby improving image sensitivity of an image sensor (e.g., CCD or CMOS). A central aperture disposed between the first lens element and the image surface is advantageous for increasing the angle of view of the optical lens assembly for photography, thereby providing a wider field of view for it.According to the present disclosure, the optical lens assembly for photography may include an aperture control unit. The aperture control unit may be a mechanical component or a light modulator that can control the size and shape of the aperture by electricity or electrical signals. The mechanical component may include a movable member, for example, a blade assembly or a light shielding film. The light modulator may include a shielding member such as a filter, an electrochromic material, or a liquid crystal layer. The aperture control unit controls the amount of incident light or the exposure time to improve the image quality adjustment capability. Moreover, the aperture control unit may be the aperture stop of the present disclosure, which changes the F-number to achieve various image effects such as the depth of field or the lens speed.According to the present disclosure, the photographing optical lens assembly may include one or more optical elements for limiting the shape of light passing through the photographing optical lens assembly. Each optical element may be, but is not limited to, a filter, a polarizer, etc., and each optical element may be, but is not limited to, a one-piece element, a composite component, a thin film, etc. The optical element may be disposed on the object side or the image side of the optical lens assembly for photography or between two adjacent lens elements to transmit light in a certain shape and thereby meet application requirements.According to the present disclosure, the optical lens assembly for photography may include at least one optical lens element, an optical element, or a carrier having at least one surface with a low reflection layer. The low reflection layer can effectively reduce stray light generated due to light reflection at the interface. The low reflection layer may be disposed in an optically non-effective area of an object-side surface or an image-side surface of the optical lens element or a connection surface between the object-side surface and the image-side surface. The optical element may be a light blocking member, an annular spacer, a tube member, a cover glass, a blue glass, a filter, a color filter, an optical path deflection member, a prism, a mirror, and so forth. The carrier may be a base for holding a lens assembly, a microlens disposed on an image sensor, a substrate surrounding the image sensor, a glass plate for protecting the image sensor, etc.According to the present disclosure, the object side and the image side are defined according to the optical axis direction, and the axial optical data is calculated along the optical axis. When the optical axis is redirected by a light redirecting element, the axial optical data is also calculated along the redirected optical axis.According to the above description of the present disclosure, the following specific embodiments are provided for further explanation.1.
