[0091] The following detailed description of the features and advantages of this utility model in the embodiments is sufficient to enable any person skilled in the art to understand the technical content of this utility model and implement it accordingly. Based on the disclosure of this specification, the scope of the claims, and the accompanying drawings, any person skilled in the art can easily understand the related objectives and advantages of this utility model. The following embodiments further illustrate the viewpoints of this utility model in detail, but are not intended to limit the scope of this utility model in any way.

[0092] This invention provides an image capturing device, comprising an imaging lens and a photosensitive element assembly. The imaging lens is disposed on the object side of the photosensitive element assembly. The photosensitive element assembly includes an electronic photosensitive element. The electronic photosensitive element is disposed on the imaging surface of the imaging lens. The photosensitive element assembly may further include elements such as a filter element, but this invention is not limited thereto.

[0093] The imaging lens includes multiple lenses, a lens barrel, a first through-hole element, and a second through-hole element.

[0094] These lenses are arranged sequentially along an optical axis. These lenses include a first lens and at least one other lens. The first lens may be the one of these lenses closest to the object side of the imaging lens. Alternatively, the first lens may be closer to the object side of the imaging lens than the at least one other lens.

[0095] The microscope tube may include a microscope tube through-hole element. Specifically, the microscope tube may include a tubular portion and the aforementioned microscope tube through-hole element, wherein the microscope tube through-hole element is fixed to the tubular portion, and the microscope tube through-hole element may include a through-hole portion.

[0096] The tubular portion surrounds the optical axis and provides space for these lenses.

[0097] The through-hole extends towards the optical axis. Furthermore, the through-hole can extend from the tubular portion towards the optical axis. The through-hole may have a lens tube light-transmitting hole, a first stepped surface, a first connecting surface, and a second stepped surface.

[0098] The light-passing aperture of the lens barrel is located on the object side of the first lens.

[0099] The first step surface can be closer to the optical axis than the second step surface. The first step surface can be closer to the light passage of the lens tube than the second step surface.

[0100] The first connecting surface connects the first step surface and the second step surface.

[0101] The second step surface may at least partially overlap with the first lens in a direction parallel to the optical axis.

[0102] A first through-hole element is disposed between the first lens and the through-hole portion to separate the first lens and the through-hole portion. The side of the first through-hole element away from the through-hole portion is supported by the first lens to maintain the distance between the first lens and the light-transmitting aperture of the first lens barrel. A gap is formed between the first through-hole element and the first stepped surface. The first through-hole element may have a first light-transmitting aperture, a third stepped surface, a second connecting surface, and a fourth stepped surface.

[0103] The first light-transmitting aperture is set to correspond to the light-transmitting aperture of the lens barrel.

[0104] The first through-hole element can substantially contact the second stepped surface of the through-hole portion. Furthermore, the third stepped surface of the first through-hole element substantially contacts the second stepped surface of the through-hole portion.

[0105] The second connecting surface extends from the side of the third step surface near the optical axis toward the first step surface. The second connecting surface and the first connecting surface are spaced apart.

[0106] The fourth step surface extends from the side of the second connecting surface closest to the first step surface towards the optical axis. The aforementioned gap is formed between the fourth step surface and the first step surface.

[0107] The second through-hole element can be a light-shielding plate. The second through-hole element is disposed in the gap. The second through-hole element can contact the through-hole portion and the first through-hole element through the first connecting surface and the second connecting surface, respectively. The second through-hole element has a second light-transmitting hole. The second light-transmitting hole is disposed opposite to the first light-transmitting hole.

[0108] By setting the first through-hole element, the distance between the first lens and the light-transmitting hole of the lens barrel can be maintained, while the second through-hole element is kept within the gap, thereby reducing the tolerance between the first light-transmitting hole and the lens and improving the optical imaging quality of the imaging lens.

[0109] Furthermore, by coordinating the arrangement of the lens barrel aperture, the first aperture, and the second aperture, the incident light at large angles can be improved, thereby avoiding glare and enhancing the optical imaging quality of the imaging lens.

[0110] In some embodiments of this utility model, by setting the through hole on the object side of the first lens, stray light entering the imaging lens can be reduced, thereby further ensuring the optical imaging quality.

[0111] In some embodiments of this invention, the design of the second stepped surface can improve the alignment between the light-transmitting aperture and the first lens, thereby maintaining optical imaging quality.

[0112] In some embodiments of this utility model, the arrangement of the first step surface, the second step surface, the third step surface, the first connecting surface, and the second connecting surface can be coordinated to align the second light-transmitting hole with the light-transmitting hole of the lens barrel, thereby ensuring optical imaging quality.

[0113] In some embodiments of this utility model, a stepped structure is formed by the third step surface, the second connecting surface and the fourth step surface, which makes it easier to maintain the second through hole element in the gap, thereby ensuring optical imaging quality.

[0114] The through-hole portion may further have a first conical surface. The first conical surface moves away from the optical axis from the lens barrel light-transmitting hole toward the direction closer to the second through-hole element.

[0115] The first through-hole element may further have a second conical surface. The second conical surface moves away from the optical axis from the first through-hole in a direction closer to the second through-hole element.

[0116] At least one of the first and second conical surfaces may include an anti-reflective structure. The anti-reflective structure surrounds the optical axis. The anti-reflective structure includes multiple protrusions. These protrusions may be arranged sequentially in the direction surrounding the optical axis. These protrusions may also be each in a ring shape and arranged sequentially in a direction away from the optical axis. Through the design of the anti-reflective structure, glare caused by the reflection of non-imaging light rays through the first or second conical surface can be reduced, thereby ensuring optical imaging quality.

[0117] The minimum thickness of the through-hole portion at the first step surface in the direction parallel to the optical axis can be less than the minimum thickness of the through-hole portion at the second step surface in the direction parallel to the optical axis. This prevents deformation during assembly and maintains optical imaging quality.

[0118] The shortest distance between the first lens and the first light-transmitting aperture can be less than the shortest distance between the second through-hole element and the first light-transmitting aperture. This reduces the risk of glare caused by light passing through the edge of the first lens, thus ensuring optical imaging quality.

[0119] The shortest distance between the first lens and the first aperture can be less than the shortest distance between the first lens and the second aperture. This improves the effect of the first aperture element in blocking stray light, thereby further ensuring optical imaging quality.

[0120] The minimum width of the gap between the first stepped surface and the first through-hole element in the direction parallel to the optical axis is G, and the shortest distance between the first stepped surface and the second stepped surface in the direction parallel to the optical axis is D12. These distances can satisfy the following conditions: 0.06 ≤ G / D12 ≤ 0.5. This maintains the gap distance and further reduces assembly tolerances. Alternatively, the following conditions can also be satisfied: 0.08 ≤ G / D12 ≤ 0.45. Furthermore, the following condition can also be satisfied: 0.1 ≤ G / D12 ≤ 0.4.

[0121] When the second through-hole element is a light-shielding plate, the minimum width of the gap between the first stepped surface and the first through-hole element in the direction parallel to the optical axis is G, and the thickness of the light-shielding plate is T, which can satisfy the following condition: 1.03 ≤ G / T ≤ 1.97. This prevents the first through-hole element from squeezing the light-shielding plate, thus avoiding deformation of the light-shielding plate. It can also satisfy the following condition: 1.1 ≤ G / T ≤ 1.92.

[0122] The lens barrel aperture, the first aperture, and the second aperture each have a maximum opening diameter. The maximum opening diameter of the lens barrel aperture is Dib, the maximum opening diameter of the first aperture is Di1, and the maximum opening diameter of the second aperture is Di2, which can satisfy the following conditions: 0.85 ≤ Dib / Di2 ≤ 1.15; and 0.85 ≤ Di1 / Di2 ≤ 1.15. This improves the optical imaging quality of large-angle incident light and avoids glare. It can also satisfy the following conditions: 0.8 ≤ Dib / Di2 ≤ 1.2; and 0.8 ≤ Di1 / Di2 ≤ 1.2. Furthermore, it can also satisfy the following conditions: 0.9 ≤ Dib / Di2 ≤ 1.1; and 0.9 ≤ Di1 / Di2 ≤ 1.1.

[0123] The minimum thickness of the through-hole portion at the first step surface in the direction parallel to the optical axis is T1, and the thickness of the first through-hole element in the direction parallel to the optical axis is TS1, which can satisfy the following condition: 0.14 ≤ T1 / TS1 ≤ 0.92. This maintains the distance between the first lens and the light-transmitting aperture of the lens barrel, thus maintaining optical imaging quality. It can also satisfy the following condition: 0.2 ≤ T1 / TS1 ≤ 0.7.

[0124] The various technical features in the imaging lens and image acquisition device of this utility model can be combined and configured to achieve the corresponding effects.

[0125] Based on the above implementation methods, specific embodiments are presented below and described in detail with reference to the accompanying drawings.

[0128] This embodiment provides an imaging lens 1, which includes multiple lenses 12, a lens barrel 14, a first through-hole element 16, and a second through-hole element 18.

[0129] Lenses 12 are arranged sequentially along an optical axis OA. Each lens 12 includes a first lens 121 and a plurality of other lenses 122. The first lens 121 is the one of the lenses 12 closest to the object side of the imaging lens 1. Alternatively, the first lens 121 is closer to the object side of the imaging lens 1 than the other lenses 122. The imaging lens 1 also includes spacers SP for separating the lenses 12 and fixtures RT for fixing the lenses 12.

[0130] The lens tube 14 includes a tubular portion 142 and a through-hole portion 144.

[0131] The tubular portion 142 surrounds the optical axis OA, and the tubular portion 142 has multiple inner annular surfaces 1420 for mounting elements such as the lens 12, the first through-hole element 16, the spacer SP, and the fixing element RT.

[0132] The through-hole portion 144 extends from the tubular portion 142 toward the optical axis OA. The through-hole portion 144 has a lens tube light-transmitting hole 144a, a first stepped surface 144b, a first connecting surface 144c, and a second stepped surface 144d.

[0133] The light-transmitting aperture 144a of the lens barrel is located on the object side of the first lens 121.

[0134] The first step surface 144b is closer to the optical axis OA than the second step surface 144d. The first step surface 144b is closer to the lens tube aperture 144a than the second step surface 144d.

[0135] The first connecting surface 144c connects the first step surface 144b and the second step surface 144d.

[0136] The second step surface 144d at least partially overlaps with the first lens 121 in a direction parallel to the optical axis OA.

[0137] A first through-hole element 16 is disposed between the first lens 121 and the through-hole portion 144 to space the first lens 121 and the through-hole portion 144. The side of the first through-hole element 16 away from the through-hole portion 144 is supported by the first lens 121 to maintain the distance between the first lens 121 and the light-transmitting aperture 144a of the lens barrel. A gap GP is formed between the first through-hole element 16 and the first stepped surface 144b. The first through-hole element 16 has a first light-transmitting aperture 166a, a third stepped surface 166b, a second connecting surface 166c, and a fourth stepped surface 166d.

[0138] The first light-transmitting aperture 166a is set to correspond with the light-transmitting aperture 144a of the lens barrel.

[0139] The third step surface 166b of the first through hole element 16 is in solid contact with the second step surface 144d of the through hole portion 144.

[0140] The second connecting surface 166c extends from the side of the third step surface 166b near the optical axis OA toward the first step surface 144b. The second connecting surface 166c and the first connecting surface 144c are spaced apart.

[0141] The fourth step surface 166d extends from the side of the second connecting surface 166c near the first step surface 144b towards the optical axis OA. The aforementioned gap GP is formed between the fourth step surface 166d and the first step surface 144b.

[0142] The second through-hole element 18 is a light-shielding plate. The second through-hole element 18 is disposed in the gap GP. The second through-hole element 18 contacts the through-hole portion 144 through the first step surface 144b and the first connecting surface 144c. The second through-hole element 18 has a second light-transmitting hole 188a. The second light-transmitting hole 188a is disposed opposite to the first light-transmitting hole 166a.

[0143] In this embodiment, the through-hole portion 144 further has a first conical surface 144e. The first conical surface 144e moves away from the optical axis OA from the lens barrel light-transmitting hole 144a toward the second through-hole element 18.

[0144] The first through-hole element 16 further has a second conical surface 166e. The second conical surface 166e is away from the optical axis OA from the first light-transmitting hole 166a in a direction closer to the second through-hole element 18.

[0145] like Figure 5As shown, the minimum thickness T1 of the through hole portion 144 at the first step surface 144b in the direction parallel to the optical axis OA is less than the minimum thickness T2 of the through hole portion 144 at the second step surface 144d in the direction parallel to the optical axis OA.

[0146] like Figure 7 As shown, the shortest distance SD1 between the first lens 121 and the first light-transmitting hole 166a is less than the shortest distance SD2 between the second through-hole element 18 and the first light-transmitting hole 166a.
