[0050] Throughout the drawings and detailed description, the same reference numerals represent the same elements. For clarity, illustration, and convenience, the drawings may not be drawn to scale, and the relative sizes, proportions, and descriptions of the elements in the drawings may be exaggerated. DETAILED DESCRIPTION

[0051] Hereinafter, although examples of the present disclosure will be described in detail with reference to the accompanying drawings, it should be noted that the examples are not limited thereto.

[0052] The following specific embodiments are provided to help the reader gain a comprehensive understanding of the methods, devices, and / or systems described herein. However, various changes, modifications, and equivalents of the methods, devices, and / or systems described herein will be apparent after understanding the present disclosure. For example, the order of operations described herein is merely an example and is not limited to the order set forth herein, but may be changed as will be apparent after understanding the present disclosure, except for operations that must occur in a certain order. In addition, descriptions of features known in the art may be omitted for clarity and brevity.

[0053] The features described herein may be implemented in different forms and are not to be construed as being limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways to implement the methods, devices, and / or systems described herein that will be apparent after understanding the present disclosure.

[0054] Throughout the specification, when an element (such as a layer, a region, or a substrate) is described as being “on”, “connected to”, or “coupled to” another element, it may be directly “on”, directly “connected to”, or directly “coupled to” the other element, or one or more other elements may be present between them. Conversely, when an element is described as being “directly” “on”, “directly connected to”, or “directly coupled to” another element, there are no other elements present between them.

[0055] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more of the associated listed items; similarly, "at least one of..." includes any one of the associated listed items and any combination of any two or more of the associated listed items.

[0056] Although terms such as "first", "second", and "third" may be used herein to describe various members, components, regions, layers, or portions, these members, components, regions, layers, or portions are not limited by these terms. Instead, these terms are only used to distinguish one member, component, region, layer, or portion from another member, component, region, layer, or portion. Therefore, the first member, first component, first region, first layer, or first portion mentioned in the examples described herein may also be referred to as the second member, second component, second region, second layer, or second portion without departing from the teachings of the examples.

[0057] In describing the present disclosure below, terms related to components of the present disclosure are named in consideration of the function of each component and thus should not be construed as limiting the technical components of the present disclosure.

[0058] For ease of description, spatially relative terms such as "above", "upper", "below", "lower", etc. may be used herein to describe the relationship of one element to another element as shown in the drawings. In addition to the orientation depicted in the drawings, such spatially relative terms are intended to also include different orientations of the device in use or operation. For example, if the device in the drawings is turned over, an element described as being "above" or "upper" relative to another element will then be "below" or "lower" relative to the other element. Therefore, the term "above" includes both the orientation of the above and below, depending on the spatial orientation of the device. The device may also be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative terms used herein will be interpreted accordingly.

[0059] The terms used herein are only used to describe various examples and are not used to limit the present disclosure. The articles "a", "an" and "the" are intended to include plural forms as well, unless the context clearly indicates otherwise. The terms "include", "comprise" and "have" specify the presence of stated features, quantities, operations, components, elements and / or combinations thereof, but do not exclude the presence or addition of one or more other features, quantities, operations, components, elements and / or combinations thereof.

[0060] Due to manufacturing techniques and / or tolerances, the shapes shown in the drawings may vary. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings but include shape variations that occur during manufacturing.

[0061] Herein, it is noted that the use of the term “may” with respect to an example, such as with respect to what an example may include or implement, means that there is at least one example that includes or implements this feature, and all examples are not limited thereto.

[0062] As will be apparent after understanding the present disclosure, the features of the examples described herein may be combined in various ways. In addition, although the examples described herein have multiple configurations, other configurations are also possible, as will be apparent after understanding the present disclosure.

[0063] One aspect of the present disclosure may be directed to providing an imaging lens system capable of achieving high-resolution imaging even in a low-light environment.

[0064] Another aspect of the present disclosure may be directed to providing an imaging lens system having a wide field of view while having a low f-number.

[0065] In this specification, the first lens refers to the lens closest to the object (or subject), and the tenth lens refers to the lens closest to the imaging plane (or image sensor). In this specification, the units of the radius of curvature, thickness, TTL (the distance from the object side of the first lens to the imaging plane), IMG HT (the height of the imaging plane), and the focal length of the lens are expressed in millimeters (mm).

[0066] The thickness of the lens, the distance between the lenses, and the TTL refer to the distance of the lenses along the optical axis. In addition, in the description of the lens shape, a configuration in which one surface is convex means that the paraxial region of the surface is convex, and a configuration in which one surface is concave means that the paraxial region of the surface is concave. Therefore, even when it is described that one surface of the lens is convex, the edge of the lens may be concave. Similarly, even when it is described that one surface of the lens is concave, the edge of the lens may be convex.

[0067] The imaging lens system described herein may be configured to be installed in a portable electronic device. For example, the imaging lens system may be installed in a smart phone, a notebook computer, an augmented reality device, a virtual reality device (VR), a portable game console, etc. However, the scope of use and examples of the imaging lens system described herein are not limited to the above-mentioned electronic devices. For example, the imaging lens system may provide a narrow installation space, but may also be applied to electronic devices that require high-resolution imaging.
