     DETAILED DESCRIPTION OF EMBODIMENTS 
     The present disclosure will be further described below in detail in combination with the accompanying drawings and the embodiments. It could be appreciated that the specific embodiments described herein are merely used for explaining the relevant invention, rather than limiting the invention. In addition, it should be noted that, for the ease of description, only the parts related to the relevant invention are shown in the accompanying drawings. 
     It should be understood that in the present disclosure, when an element or a layer is referred to as being “on,” “connected to” or “coupled to” another element or layer, it may be directly on, connected or coupled to another element or layer, or an intervening element or layer may be present. When an element is referred to as being “directly on,” “directly connected to” or “directly coupled to” another element or layer, there are no intervening elements or layers present. The same reference numerals designate the same elements throughout this specification. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. 
     It should be understood that, although terms such as “first” and “second” may be used herein to describe various elements, components, areas, layers and/or sections, these elements, components, areas, layers and/or sections should not be limited by these terms. These terms are used to distinguish one element, component, area, layer or section from another element, component, area, layer or section. Thus, a first element, component, area, layer or section discussed below could be termed a second element, component, area, layer or section without departing from the teachings of the present disclosure. 
     The terminology used herein is for the purpose of describing specific implementations only and is not intended to limit the present disclosure. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should be further understood that the terms “comprising,” “including,” “having” and variants thereof, when used in this specification, specify the presence of stated features, entireties, steps, operations, elements and/or components, but do not preclude the presence or addition of one or more other features, entireties, steps, operations, elements, components and/or groups thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items. Expressions such as “at least one of,” when preceding a list of elements, modify the entire list of elements rather than an individual element in the list. Further, the use of “may,” when describing implementations of the present disclosure, relates to “one or more implementations of the present disclosure.” In addition, the term “exemplary” is intended to refer to an example or illustration. 
     Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the present disclosure belongs. It should be further understood that terms (i.e., those defined in commonly used dictionaries) should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. 
     It should also be noted that the embodiments in the present disclosure and the features in the embodiments may be combined with each other on a non-conflict basis. The present disclosure will be described below in detail with reference to the accompanying drawings and in combination with the embodiments. 
     The present disclosure provides an imaging lens assembly. The imaging lens assembly according to the present disclosure is provided with, sequentially from an object side to an image side of the imaging lens assembly, a first lens having a positive refractive power, a second lens having a negative refractive power, and at least one subsequent lens. In embodiments of the present disclosure, an object-side surface of the first lens is a convex surface, and an image-side surface of the second lens is a concave surface. In the embodiments of the present disclosure, at least one of the first lens, the second lens, or the at least one subsequent lens is a glass aspheric lens. 
     In an implementation, the at least one subsequent lens includes, sequentially from the second lens to the image side along an optical axis, a third lens, a fourth lens, and a fifth lens. The third lens may have a positive refractive power, the fourth lens may have a negative refractive power, and the fifth lens may have a negative refractive power. 
     In an implementation, the at least one subsequent lens includes, sequentially from the second lens to the image side along an optical axis, a third lens, a fourth lens, a fifth lens, and a sixth lens. The third lens may have a positive refractive power or a negative refractive power, and the fourth lens may have a positive refractive power or a negative refractive power. The fifth lens may have a positive refractive power or a negative refractive power, and the sixth lens may have a positive refractive power or a negative refractive power. 
     In the embodiments of the present disclosure, a transmittance T 1  of the imaging lens assembly corresponding to a wave band of 650 nm satisfies: T 1 &gt;85%. A transmittance T 2  of the imaging lens assembly corresponding to a wave band of 490 nm satisfies: T 2 &gt;88%. A transmittance T 3  of the imaging lens assembly corresponding to a wave band of 430 nm satisfies: T 3 &gt;75%. An optical lens of glass material is used in the imaging lens assembly of the present disclosure, so that the lens assembly has a higher transmittance, and thus the lens assembly has higher brightness, a higher permeability, and a higher color reproduction performance during the imaging. 
     In the embodiments of the present disclosure, an influence ratio dng/dt of a unit temperature to a unit refractive index of the glass aspheric lens and a influence ratio dni/dt of a unit temperature to a unit refractive index of a lens closest to the image side satisfy: |dng/dt|/|dni/dt|&lt;0.1, and more specifically, satisfy: |dng/dt|/|dni/dt|≤0.03. By satisfying the above relationship, it may be ensured that the lens assembly has high resolution at different temperatures, which reduces the sensitivity of the lens assembly to the temperature. 
     In the embodiments of the present disclosure, an abbe number Vg of the glass aspheric lens and an abbe number Vi of the lens closest to the image side satisfy: 0.35&lt;Vg/Vi&lt;1.5, and more specifically, satisfy: 0.37≤Vg/Vi≤1.46. When the glass lens is used in the imaging lens assembly of the present disclosure, the abbe number of the glass lens is reasonably distributed by satisfying the above relationship, which is conductive to greatly reducing the chromatic aberration of the optical system. 
     In the embodiments of the present disclosure, a refractive index Ng of the glass aspheric lens satisfies: 1.5≤Ng≤2.0, and more specifically, satisfies: 1.5≤Ng≤1.92. By satisfying the above relationship, the range of the refractive index of the glass lens is reasonably selected to avoid the use of the high-priced glass, thereby ensuring the cost of the lens assembly. 
     In the embodiments of the present disclosure, an effective focal length f of the imaging lens assembly and an entrance pupil diameter of the imaging lens assembly satisfy: 1.5&lt;f/EPD&lt;2.5, and more specifically, satisfy: 1.68≤f/EPD≤2.28. The imaging lens assembly satisfying the above relationship has a larger luminous flux, which makes the lens assembly acquire sufficiently high brightness. 
     In the embodiments of the present disclosure, the effective focal length f of the imaging lens assembly and an effective focal length fg of the glass aspheric lens satisfy: −0.6&lt;f/fg&lt;1.2, and more specifically, −0.52≤f/fg≤1.05. By satisfying the above relationship, the refractive power of the glass lens in the entire system can be reasonably distributed, which makes the system acquire a higher MTF performance. 
     In the embodiments of the present disclosure, the effective focal length f of the imaging lens assembly and a radius of curvature R 1  of the object-side surface of the first lens satisfy: 2&lt;f/R 1 &lt;4, and more specifically, satisfy: 2.35≤f/R 1 ≤3.85. By satisfying the above relationship, the radius of curvature of the object-side surface of the first lens is set within a reasonable range, which ensures that the entire lens assembly has a good tolerance sensitivity, to match the processing capability. 
     In the embodiments of the present disclosure, the radius of curvature R 1  of the object-side surface of the first lens and a radius of curvature R 4  of the image-side surface of the second lens satisfy: 0&lt;R 1 /R 4 &lt;1.0, and more specifically, satisfy: 0.43≤R 1 /R 4 ≤0.91. By satisfying the above relationship, the curvature of the first lens can be effectively matched with the curvature of the second lens, and thus the lateral chromatic aberration of the system may be reduced, which ensures that the color reproduction during the use of the chip is not affected. 
     The present disclosure is further described below in combination with specific embodiments.

     Here, x is the sag—the axis-component of the displacement of the surface from the aspheric vertex, when the surface is at height h from the optical axis; c is the paraxial curvature of the aspheric surface, and c=1/R (i.e., the paraxial curvature c is the reciprocal of the radius of curvature R in Table 2 above); k is the conic coefficient (given in Table 2); and Ai is the correction coefficient of the i th  order of the aspheric surface. 
     Table 3 below shows the high-order coefficients A 4 , A 6 , A 8 , A 10 , A 12 , A 14 , and A 16  applicable to the aspheric surfaces S 1 -S 12  of the aspheric lenses in this embodiment.

     The second lens E 2  may have a negative refractive power, an object-side surface S 3  of the second lens E 2  may be a convex surface, and an image-side surface S 4  of the second lens E 2  may be a concave surface. 
     The third lens E 3  may have a positive refractive power, an object-side surface S 5  of the third lens E 3  may be a convex surface, and an image-side surface S 6  of the third lens E 3  may be a convex surface. 
     The fourth lens E 4  may have a positive refractive power, an object-side surface S 7  of the fourth lens E 4  may be a concave surface, and an image-side surface S 8  of the fourth lens E 4  may be a convex surface. 
     The fifth lens E 5  may have a positive refractive power, an object-side surface S 9  of the fifth lens E 5  may be a concave surface, and an image-side surface S 10  of the fifth lens E 5  may be a convex surface. 
     The sixth lens E 6  may have a negative refractive power, an object-side surface S 11  of the sixth lens E 6  may be a convex surface, and an image-side surface S 12  of the sixth lens E 6  may be a concave surface. 
     Table 4 below shows the effective focal lengths f 1 -f 6  of the first to sixth lenses E 1 -E 6 , the total effective focal length f of the imaging lens assembly, the total length TTL of the imaging lens assembly, and the half of the maximal field-of-view HFOV of the imaging lens assembly.

     Embodiment 3 
     An imaging lens assembly according to Embodiment 3 of the present disclosure is described below with reference to  FIGS. 11-15 . 
       FIG. 11  is a schematic structural diagram illustrating the imaging lens assembly according to Embodiment 3. The imaging lens assembly includes, sequentially from an object side to an image side, a first lens E 1 , a second lens E 2 , a third lens E 3 , a fourth lens E 4 , a fifth lens E 5 , and a sixth lens E 6 . 
     The first lens E 1  may have a positive refractive power. An object-side surface S 1  of the first lens E 1  may be a convex surface, and an image-side surface S 2  of the first lens E 1  is a concave surface. 
     The second lens E 2  may have a negative refractive power. An object-side surface S 3  of the second lens E 2  may be a convex surface, and an image-side surface S 4  of the second lens E 2  may be a concave surface. 
     The third lens E 3  may have a positive refractive power. An object-side surface S 5  of the third lens E 3  may be a convex surface, and an image-side surface S 6  of the third lens E 3  may be a concave surface. 
     The fourth lens E 4  may have a positive refractive power. An object-side surface S 7  of the fourth lens E 4  may be a convex surface, and an image-side surface S 8  of the fourth lens E 4  may be a concave surface. 
     The fifth lens E 5  may have a positive refractive power. An object-side surface S 9  of the fifth lens E 5  may be a convex surface, and an image-side surface S 10  of the fifth lens E 5  may be a convex surface. 
     The sixth lens E 6  may have a negative refractive power. An object-side surface S 11  of the sixth lens E 6  may be a concave surface, and an image-side surface S 12  of the sixth lens E 6  may be a concave surface. 
     Table 7 below shows the effective focal lengths f 1 -f 6  of the first to sixth lenses E 1 -E 6 , the total effective focal length f of the imaging lens assembly, the total length TTL of the imaging lens assembly, and the half of the maximal field-of-view HFOV of the imaging lens assembly.
