DETAILED DESCRIPTION

An optical imaging lens assembly includes nine lens elements. The nine lens elements are, in order from an object side to an image side along an optical path, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, a seventh lens element, an eighth lens element and a ninth lens element. Each of the nine lens elements of the optical imaging lens assembly has an object-side surface facing toward the object side and an image-side surface facing toward the image side.

The first lens element has negative refractive power. Therefore, it is favorable for enlarging the field of view so as to capture image data of wider range.

The second lens element has negative refractive power. Therefore, it is favorable for effectively balancing the refractive power of the first lens element so as to prevent overly large curvature of the first lens element causing excessive aberrations. The object-side surface of the second lens element can be convex in a paraxial region thereof. Therefore, it is favorable for adjusting the surface shape and refractive power of the second lens element so as to improve image quality at the paraxial region. The image-side surface of the second lens element is concave in a paraxial region thereof. Therefore, it is favorable for adjusting the shape of the image-side surface of the second lens element so as to correct aberrations generated by large incident angle.

The image-side surface of the third lens element can be convex in a paraxial region thereof. Therefore, it is favorable for balancing spherical aberration and coma.

The object-side surface of the fourth lens element can be concave in a paraxial region thereof. Therefore, it is favorable for balancing the incident angle of light in the optical imaging lens assembly with a large view angle so as to prevent divergence of light rays. The image-side surface of the fourth lens element is convex in a paraxial region thereof. Therefore, it is favorable for the fourth lens element to have light converging capability so as to prevent insufficient refraction of light from the peripheral region which may cause ineffective light convergence.

The fifth lens element can have positive refractive power. Therefore, it is favorable for converging light so as to reduce the size of the optical imaging lens assembly. The object-side surface of the fifth lens element can be convex in a paraxial region thereof. Therefore, it is favorable for adjusting the surface shape and refractive power of the fifth lens element so as to reduce the size and correct aberrations.

The sixth lens element can have negative refractive power. Therefore, it is favorable for balancing the refractive power of the seventh lens element and reducing the back focal length. The image-side surface of the sixth lens element is concave in a paraxial region thereof. Therefore, it is favorable for adjusting the refraction direction of light rays from the sixth lens element so as to enlarge the image surface.

The object-side surface of the seventh lens element can be convex in a paraxial region thereof. Therefore, it is favorable for reducing the back focal length and correcting off-axis aberrations.

The eighth lens element has negative refractive power. Therefore, it is favorable for effectively controlling the back focal length of the optical imaging lens assembly so as to prevent excessive long total track length of the optical imaging lens assembly. The object-side surface of the eighth lens element is concave in a paraxial region thereof. Therefore, it is favorable for controlling the angle of light incident onto the object-side surface of the eighth lens element so as to prevent overly large incident angle which may cause divergence of light rays and low illuminance at the periphery region of the image.

Among the nine lens elements of the optical imaging lens assembly, there can be at least one lens element having at least one inflection point. In detail, among the first lens element through the ninth lens element, there can be one or more lens elements each having at least one inflection point, and said one lens element having at least one inflection point refers to a lens element in which at least one of the object-side surface and the image-side surface has at least one inflection point. Therefore, it is favorable for increasing the optical design flexibility for manufacturing of lens elements and correcting aberrations. Moreover, at least one of the object-side surface and the image-side surface of the third lens element can have at least one inflection point. Therefore, it is favorable for adjusting the peripheral shape design of the third lens element so as to correct astigmatism. Moreover, the object-side surface of the third lens element can have at least one inflection point. Moreover, the image-side surface of the eighth lens element can have at least one inflection point. Therefore, it is favorable for adjusting the angle of light incident onto the image surface so as to control the angle of peripheral light rays, thereby preventing vignetting in the peripheral region of the image and reducing distortion. Moreover, at least one of the object-side surface and the image-side surface of the ninth lens element can have at least one inflection point. Therefore, it is favorable for enhancing the aberration correction capability of the ninth lens element at the peripheral region of images. Please refer to FIG. 33, which shows a schematic view of inflection points P of the third lens element E3, the seventh lens element E7, the eighth lens element E8 and the ninth lens element E9 according to the 1st embodiment of the present disclosure.

According to the present disclosure, the aforementioned features and conditions can be utilized in numerous combinations so as to achieve corresponding effects.

According to the present disclosure, the lens elements of the optical imaging lens assembly can be made of either glass or plastic material. When the lens elements are made of glass material, the refractive power distribution of the optical imaging lens assembly may be more flexible, and the influence on imaging caused by external environment temperature change may be reduced. The glass lens element can either be made by grinding or molding. When the lens elements are made of plastic material, the manufacturing costs can be effectively reduced. Furthermore, surfaces of each lens element can be arranged to be spherical or aspheric. Spherical lens elements are simple in manufacture. Aspheric lens element design allows more control variables for eliminating aberrations thereof and reducing the required number of lens elements, and the total track length of the optical imaging lens assembly can therefore be effectively shortened. Additionally, the aspheric surfaces may be formed by plastic injection molding or glass molding.

According to the present disclosure, when a lens surface is aspheric, it means that the lens surface has an aspheric shape throughout its optically effective area, or a portion(s) thereof.

According to the present disclosure, one or more of the lens elements' material may optionally include an additive which generates light absorption and interference effects and alters the lens elements' transmittance in a specific range of wavelength for a reduction in unwanted stray light or color deviation. 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 may optionally filter out light in the wavelength range of 350 nm to 450 nm to reduce excessive blue light and/or near ultraviolet light from interfering the final image. The additive may be homogeneously mixed with a plastic material to be used in manufacturing a mixed-material lens element by injection molding. Moreover, the additive may be coated on the lens surfaces to provide the abovementioned effects.

According to 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 away from the paraxial region. Particularly, unless otherwise stated, 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. Moreover, when a region of refractive power or focus of a lens element is not defined, it indicates that the region of refractive power or focus of the lens element is in the paraxial region thereof.

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 where its tangent is perpendicular to the optical axis. Please refer to FIG. 33, which shows a schematic view of critical points C of the third lens element E3, the eighth lens element E8 and the ninth lens element E9 according to the 1st embodiment of the present disclosure. In FIG. 33, the object-side surface of the third lens element E3 and the image-side surface of the ninth lens element E9 each has a critical point C in an off-axis region thereof, and the image-side surface of the eighth lens element E8 and the object-side surface of the ninth lens element E9 each has two critical points C in an off-axis region thereof. The 1st embodiment of the present disclosure shown in FIG. 33 is only exemplary. Each of the lens elements in various embodiments of the present disclosure can have one or more critical points in an off-axis region thereof.

According to the present disclosure, the image surface of the optical imaging lens assembly, based on the corresponding image sensor, can be flat or curved, especially a curved surface being concave facing towards the object side of the optical imaging lens assembly.

According to the present disclosure, an image correction unit, such as a field flattener, can be optionally disposed between the lens element closest to the image side of the optical imaging lens assembly along the optical path and the image surface for correction of aberrations such as field curvature. The optical characteristics of the image correction unit, such as curvature, thickness, index of refraction, position and surface shape (convex or concave surface with spherical, aspheric, diffractive or Fresnel types), can be adjusted according to the design of the image capturing unit. In general, a preferable image correction unit is, for example, a thin transparent element having a concave object-side surface and a planar image-side surface, and the thin transparent element is disposed near the image surface.

According to the present disclosure, at least one light-folding element, such as a prism or a mirror, can be optionally provided between an imaged object and the image surface on the imaging optical path, and the surface shape of the prism or mirror can be planar, spherical, aspheric or freeform surface, such that the optical imaging lens assembly can be more flexible in space arrangement, and therefore the dimensions of an electronic device is not restricted by the total track length of the optical imaging lens assembly. Specifically, please refer to FIG. 35 and FIG. 36. FIG. 35 shows a schematic view of a configuration of one light-folding element in an optical imaging lens assembly according to one embodiment of the present disclosure, and FIG. 36 shows a schematic view of another configuration of one light-folding element in an optical imaging lens assembly according to one embodiment of the present disclosure. In FIG. 35 and FIG. 36, the optical imaging lens assembly can have, in order from an imaged object (not shown in the figures) to an image surface IMG along an optical path, a first optical axis OA1, a light-folding element LF and a second optical axis OA2. The light-folding element LF can be disposed between the imaged object and a lens group LG of the optical imaging lens assembly as shown in FIG. 35, or disposed between a lens group LG and the image surface IMG of the optical imaging lens assembly as shown in FIG. 36. Furthermore, please refer to FIG. 37, which shows a schematic view of a configuration of two light-folding elements in an optical imaging lens assembly according to one embodiment of the present disclosure.

The first light-folding element LF1 is disposed between the imaged object and a lens group LG of the optical imaging lens assembly, the second light-folding element LF2 is disposed between the lens group LG and the image surface IMG of the optical imaging lens assembly, and the travelling direction of light on the first optical axis OA1 can be the same direction as the travelling direction of light on the third optical axis OA3 as shown in FIG. 37. The optical imaging lens assembly can be optionally provided with three or more light-folding elements, and the present disclosure is not limited to the type, amount and position of the light-folding elements of the embodiments disclosed in the aforementioned figures.

According to the present disclosure, the optical imaging 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 set for eliminating the stray light and thereby improving image quality thereof.

According to 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 optical imaging lens assembly and the image surface to produce a telecentric effect, and thereby improves the image-sensing efficiency of an image sensor (for example, CCD or CMOS). A middle stop disposed between the first lens element and the image surface is favorable for enlarging the viewing angle of the optical imaging lens assembly and thereby provides a wider field of view for the same.

According to the present disclosure, the optical imaging lens assembly can include an aperture control unit. The aperture control unit may be a mechanical component or a light modulator, which can control the size and shape of the aperture through electricity or electrical signals. The mechanical component can include a movable member, such as a blade assembly or a light shielding sheet. The light modulator can include a shielding element, such as a filter, an electrochromic material or a liquid-crystal layer. The aperture control unit controls the amount of incident light or exposure time to enhance the capability of image quality adjustment. In addition, the aperture control unit can be the aperture stop of the present disclosure, which changes the f-number to obtain different image effects, such as the depth of field or lens speed.

According to the present disclosure, the optical imaging lens assembly can include one or more optical elements for limiting the form of light passing through the optical imaging lens assembly. Each optical element can be, but not limited to, a filter, a polarizer, etc., and each optical element can be, but not limited to, a single-piece element, a composite component, a thin film, etc. The optical element can be located at the object side or the image side of the optical imaging lens assembly or between any two adjacent lens elements so as to allow light in a specific form to pass through, thereby meeting application requirements.

According to the present disclosure, the optical imaging lens assembly can include at least one optical lens element, an optical element, or a carrier, which has 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 can be disposed in an optical non-effective area of an object-side surface or an image-side surface of the said optical lens element, or a connection surface between the object-side surface and the image-side surface. The said optical element can be a light-blocking element, an annular spacer, a barrel element, a cover glass, a blue glass, a filter, a color filter, an optical path folding element (e.g., a reflective element), a prism, a mirror, etc. The said carrier can be a base for supporting a lens assembly, a micro lens 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 image side are defined in accordance with the direction of the optical axis, and the axial optical data are calculated along the optical axis. Furthermore, if the optical axis is deflected by a light-folding element, the axial optical data are also calculated along the deflected optical axis.

11th Embodiment

FIG. 21 is a perspective view of an image capturing unit according to the 11th embodiment of the present disclosure. In this embodiment, an image capturing unit 100 is a camera module including a lens unit 101, a driving device 102, an image sensor 103 and an image stabilizer 104. The lens unit 101 includes the optical imaging lens assembly as disclosed in the 1st embodiment, a barrel and a holder member (their reference numerals are omitted) for holding the optical imaging lens assembly. However, the lens unit 101 may alternatively be provided with the optical imaging lens assembly as disclosed in other embodiments of the present disclosure, and the present disclosure is not limited thereto. The imaging light converges in the lens unit 101 of the image capturing unit 100 to generate an image with the driving device 102 utilized for image focusing on the image sensor 103, and the generated image is then digitally transmitted to other electronic component for further processing.

The driving device 102 can have auto focusing functionality, and different driving configurations can be obtained through the usages of voice coil motors (VCM), micro electro-mechanical systems (MEMS), piezoelectric systems or shape memory alloy materials. The driving device 102 is favorable for obtaining a better imaging position of the lens unit 101, so that a clear image of the imaged object can be captured by the lens unit 101 with different object distances. The image sensor 103 (for example, CMOS or CCD), which can feature high photosensitivity and low noise, is disposed on the image surface of the optical imaging lens assembly to provide higher image quality.
