Cross Reference to Related Applications
The present application claims the benefit of priority of korean patent application No. 10-2022-0168000, filed on the korean intellectual property agency at month 5 of 2022, the entire disclosure of which is incorporated herein by reference for all purposes.

Detailed Description
Hereinafter, although examples of the present disclosure will be described in detail with reference to the accompanying drawings, it should be noted that examples are not limited thereto.
The following detailed description is provided to assist the reader in obtaining a thorough understanding of the methods, apparatus, and/or systems described herein. However, various changes, modifications, and equivalents of the methods, devices, and/or systems described herein will be apparent after an understanding of 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 altered as will be apparent after an understanding of the disclosure, except for operations that must occur in a certain order. In addition, descriptions of features known in the art may be omitted for the sake of clarity and conciseness.
The features described herein may be implemented in different forms and are not to be construed as limited to the examples described herein. Rather, the examples described herein are provided merely to illustrate some of the many possible ways to implement the methods, devices, and/or systems described herein that will be apparent upon an understanding of the present disclosure.
Throughout the specification, when an element (such as a layer, region or substrate) is referred to as being "on," "connected to" or "coupled to" another element, it can be directly on, connected to or coupled to the other element or one or more other elements intervening therebetween. In contrast, when an element is referred to as being "directly on," "directly connected to," or "directly coupled to" another element, there are no other elements intervening therebetween.
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; likewise, "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.
Although terms such as "first," "second," and "third" may be used herein to describe various elements, components, regions, layers or sections, these elements, components, regions, layers or sections should not be limited by these terms. Rather, these terms are only used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Thus, a first member, first component, first region, first layer, or first portion mentioned in examples described herein may also be referred to as a second member, second component, second region, second layer, or second portion without departing from the teachings of the examples.
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 technical components of the present disclosure.
Spatially relative terms, such as "above," "upper," "lower," and the like, may be used herein for ease of description to describe one element's relationship to another element as illustrated in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "above" or "upper" relative to another element would then be "below" or "lower" relative to the other element. Thus, the term "above" includes both above and below orientations, depending on the spatial orientation of the device. The device may also be oriented in other ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
The terminology used herein is for the purpose of describing various examples only and is not intended to be limiting of the disclosure. The articles "a," "an," and "the" are intended to also include the plural forms unless the context clearly indicates otherwise. The terms "comprises," "comprising," and "having" specify the presence of stated features, amounts, operations, components, elements, and/or combinations thereof, but do not preclude the presence or addition of one or more other features, amounts, operations, components, elements, and/or groups thereof.
The shapes of the illustrations as a result of manufacturing techniques and/or tolerances, are to be expected to vary. Accordingly, examples described herein are not limited to the particular shapes shown in the drawings, but include shape changes that occur during manufacture.
In this context, it is noted that the term "may" is used with respect to an example, for example with respect to what an example may include or implement, meaning that there is at least one example that includes or implements this feature, and that all examples are not limited thereto.
As will be apparent after an understanding of the present disclosure, the features of the examples described herein may be combined in various ways. Further, while the examples described herein have a variety of configurations, other configurations are possible as will be apparent after an understanding of the present disclosure.
An aspect of the present disclosure may be directed to providing an imaging lens system capable of achieving high resolution imaging even in low light environments.
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.
In this specification, the first lens refers to a lens nearest to an object (or subject), and the tenth lens refers to a lens nearest to an imaging plane (or image sensor). In this specification, units of a radius of curvature, a thickness, TTL (distance from an object side surface of the first lens to an imaging surface), IMG HT (height of the imaging surface), and a focal length of the lens are expressed in millimeters (mm).
The thickness of the lenses, the distance between the lenses, and TTL refer to the distance of the lenses along the optical axis. Further, 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. Thus, 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.
