The connecting surface connects the optically effective surface and the outer diameter surface. The reflective element carrier is configured to fix the reflective element and embed the reflective element therein, and the reflective element and the reflective element carrier are integrally formed by insert molding. The optically effective surface is a plane. The reflective element carrier includes a covering portion disposed on the connecting surface. When the reflective element is viewed in a direction parallel to the normal axis, the edge profile of the outer diameter surface is shielded by the covering portion of the reflective element carrier. The maximum profile area is Ac, the optically effective area is Ao, and the height difference between the optically effective surface and a surface of the covering portion in the direction parallel to the normal axis is ΔH, which satisfies the following conditions: 0 mm 2 Ao < Ac ≤ 250 mm 2 ; and -0.15 mm ≤ ΔH ≤ 0.005 mm. In this way, the folding of the light path by the reflective element helps to miniaturize the imaging lens.

[0158] Specifically, the optically effective surface can provide the normal axis, and the incident light path can be reflected symmetrically about the normal axis to the emergent light path. The optically effective area can be the total area exposed after the reflective element is embedded in the reflective element carrier, and the range of the maximum profile area shielded by the covering portion of the reflective element carrier is excluded, but the present disclosure is not limited thereto. The reflective element can be a mirror element, and the reflective element carrier can be made of black plastic, but the present disclosure is not limited thereto. The edge profile can be a profile line of the outer diameter surface projected onto a plane perpendicular to the normal axis in a direction parallel to the normal axis, and the maximum profile area is the area enclosed by the profile line, wherein the plane is in the same plane as the optically effective surface. In the reflective element, the edge profile of the outer diameter surface can be partially shielded or fully shielded by the covering portion of the reflective element carrier. When the optically effective surface is higher than a surface of the covering portion in the direction parallel to the normal axis, ΔH is defined as a positive value; and when the optically effective surface is lower than a surface of the covering portion in the direction parallel to the normal axis, ΔH is defined as a negative value.

[0159] The reflective element carrier can further include an opposite portion disposed between the outer diameter surface and the opposite surface, and the covering portion and the opposite portion overlap in the direction parallel to the normal axis. Therefore, the reflective element carrier embeds and fixes the reflective element therein through the covering portion and the opposite portion, which can reduce the assembly error between the reflective element and the reflective element carrier; that is, the reflective element and the reflective element carrier can be prevented from coming loose.

[0160] The reflective element carrier can further comprise an opposite portion disposed between the outer diameter surface and the opposite surface, and the covering portion and the opposite portion do not overlap along the direction parallel to the normal axis. Therefore, by disposing the covering portion and the opposite portion of the reflective element carrier in a staggered manner, the design margin of the mold can be improved. Specifically, the covering portion and the opposite portion of the reflective element carrier can be disposed alternately along a circumferential direction around the normal axis, but the present disclosure is not limited thereto. In this way, the reflective element and the reflective element carrier are not detached.

[0161] The optically effective surface of the reflective element has a surface precision PV, and the incident light path and the normal axis have an included angle θ' using a detection wavelength λ, which satisfies the following conditions: PV < λ / 5; and 0 degrees < θ' < 90 degrees. By configuring a preferable surface precision setting range, it can be ensured that the reflected image is not distorted, and the imaging quality is improved. Specifically, λ can be 625 nm, λ / 5 can be 125 nm, λ / 10 can be 62.5 nm, or λ can be 632.8 nm, λ / 5 can be 126.56 nm, and λ / 10 can be 63.28 nm, but the present disclosure is not limited thereto. θ' can be 45 degrees, but the present disclosure is not limited thereto.

[0162] The maximum profile area is Ac, and the optically effective area is Ao, which satisfies the following conditions: 0 mm 2 Ao < Ac ≤ 200 mm 2 By configuring a preferable area setting range, it is beneficial to the miniaturization of the imaging lens.

[0163] The height difference between the optically effective surface and the surface of the covering portion along the direction parallel to the normal axis is ΔH, which satisfies the following conditions: -0.1 mm ≤ ΔH ≤ 0.003 mm. In this way, the optically effective surface does not protrude from the surface of the covering portion of the reflective element carrier, and it can be ensured that the optically effective surface will not be damaged by the mold, and the product yield is improved.

[0164] The reflective element carrier can further comprise a positioning structure. By means of the positioning structure, the reflective element and the reflective element carrier are accurately positioned, and the product quality is improved. Specifically, in the insert injection process, the reflective element is first positioned with the positioning structure at the end of the mold, then plastic injection molding is performed, the reflective element carrier covering the reflective element is formed, and after demolding, the part is transferred to the hole left by the positioning structure at the end of the original mold. This hole is the positioning structure.

[0165] The imaging lens has an optical axis, and the optical axis and the incident light path can be parallel to each other. Under certain conditions, the optical axis can also meet the definition of the incident light path, that is, the optical axis is the incident light path, which can be turned by the reflective element.

The reflective element has a normal axis, and the reflective element is used to fold an incident light path to an emergent light path symmetrically about the normal axis. The reflective element includes an optically effective surface, an opposite surface, an outer diameter surface, and a connecting surface. The normal axis passes through the optically effective surface perpendicularly, and the area passed through by the normal axis can define an optically effective area. The opposite surface is disposed opposite to the optically effective surface. The outer diameter surface surrounds the optically effective surface and can define an edge profile, and the edge profile can define a maximum profile area. The connecting surface connects the optically effective surface and the outer diameter surface. The reflective element carrier is used to fix the reflective element and embed the reflective element therein, and the reflective element and the reflective element carrier are made by insert molding. The optically effective surface is a plane. The reflective element carrier includes a covering portion disposed on the connecting surface. When the reflective element is observed in a direction parallel to the normal axis, the edge profile of the outer diameter surface is shielded by the covering portion of the reflective element carrier. The maximum profile area is Ac, the optically effective area is Ao, and the angle occupied by the range of the maximum profile area shielded by the covering portion in a circumferential direction about the normal axis is θ, which satisfies the following conditions: 0 mm 2 Ao < Ac ≤ 250 mm 2 ; and 180 degrees ≤ θ ≤ 360 degrees. In this way, the folding of the light path by the reflective element helps to miniaturize the imaging lens.

[0169] The reflective element carrier can further include an opposite portion disposed between the outer diameter surface and the opposite surface, and the covering portion and the opposite portion overlap in the direction parallel to the normal axis. Thus, the reflective element carrier embeds and fixes the reflective element therein through the covering portion and the opposite portion, which can reduce the assembly error between the reflective element and the reflective element carrier.

[0170] The reflective element carrier further includes an opposite portion disposed between the outer diameter surface and the opposite surface, and the covering portion and the opposite portion do not overlap in the direction parallel to the normal axis. Thus, the covering portion and the opposite portion of the reflective element carrier are arranged in a staggered manner, which can improve the mold design margin.

[0171] The optically effective surface of the reflective element has a surface precision PV, and an incident light path and the normal axis have an included angle θ' using a detection wavelength λ, which satisfies the following conditions: PV < λ / 5; and 0 degrees < θ' < 90 degrees. Thus, by setting a preferable surface precision range, it can be ensured that the reflected image is not distorted, and the imaging quality is improved.

[0172] The maximum contour area is Ac, and the optical effective area is Ao, which satisfies the following conditions: 0mm 2 Ao < Ac ≤ 200mm 2 Therefore, by setting the area range, the imaging lens is miniaturized.

The opposite surface is arranged opposite to the optical effective surface. The outer diameter surface surrounds the optical effective surface and can define an edge contour, and the edge contour can define a maximum contour area. The connecting surface connects the optical effective surface and the outer diameter surface. The reflective element carrier is used to fix the reflective element and embed the reflective element therein, and the reflective element and the reflective element carrier are made by one-piece molding. The optical effective surface is a plane. The reflective element carrier includes a covering portion arranged on the connecting surface. When the reflective element is observed in a direction parallel to the normal axis, the edge contour of the outer diameter surface is shielded by the covering portion of the reflective element carrier. The height difference between the optical effective surface and a surface of the covering portion in the direction parallel to the normal axis is ΔH, which satisfies the following condition: -0.15mm ≤ ΔH ≤ 0.005mm. Therefore, the folding of the light path by the reflective element helps to miniaturize the imaging lens.

[0174] The reflective element carrier can further include an opposite portion arranged between the outer diameter surface and the opposite surface, and the covering portion and the opposite portion overlap in the direction parallel to the normal axis. Therefore, the reflective element carrier embeds and fixes the reflective element therein through the covering portion and the opposite portion, which can reduce the assembly error between the reflective element and the reflective element carrier.

[0175] The reflective element carrier can further include an opposite portion arranged between the outer diameter surface and the opposite surface, and the covering portion and the opposite portion do not overlap in the direction parallel to the normal axis. By arranging the covering portion and the opposite portion of the reflective element carrier in a staggered manner, the mold design margin can be improved.

[0176] The optical effective surface of the reflective element has a surface precision PV, and the incident light path and the normal axis have an included angle θ' using a detection wavelength λ, which satisfies the following conditions: PV < λ / 5; and 0 degrees < θ' < 90 degrees. Therefore, by setting the surface precision range, the image after reflection can be ensured to be not distorted, and the imaging quality is improved.

[0177] The height difference between the optical effective surface and the surface of the covering portion in the direction parallel to the normal axis is ΔH, which satisfies the following condition: -0.1 mm≤ΔH≤0.003 mm. In this way, the optical effective surface is not protruded from the surface of the covering portion of the reflective element carrier, and the optical effective surface is not damaged by the mold, thereby improving the yield of the product.

[0178] The present disclosure provides an imaging lens, which includes a reflective element and a reflective element carrier. The reflective element has a normal axis, and the reflective element is used to fold an incident light path to an emergent light path symmetrically about the normal axis. The reflective element includes an optical effective surface, an opposite surface, an outer diameter surface, and a connecting surface. The normal axis is perpendicular to the optical effective surface, and the area through which the normal axis passes can define an optical effective area. The opposite surface is arranged opposite to the optical effective surface. The outer diameter surface surrounds the optical effective surface and can define an edge profile, and the edge profile can define a maximum profile area. The connecting surface connects the optical effective surface and the outer diameter surface. The reflective element carrier is used to fix the reflective element and embed the reflective element therein, and the reflective element and the reflective element carrier are integrally formed by insert molding. The optical effective surface is a plane. The reflective element carrier includes a covering portion arranged on the connecting surface.

The reflective element carrier further includes a step structure, and the step structure includes a step surface. The step structure is arranged adjacent to the optical effective surface. The height difference between the step surface and a surface of the covering portion in the direction parallel to the normal axis is ΔE, which satisfies the following condition: -0.25 mm≤ΔE≤0.25 mm. In this way, the folding of the light path by the reflective element helps to miniaturize the imaging lens.

[0179] Specifically, the step surface of the step structure can be a parting position in the mold design, but the present disclosure is not limited thereto. When the step surface is higher than a surface of the covering portion in the direction parallel to the normal axis, ΔE is defined as a positive value; and when the step surface is lower than a surface of the covering portion in the direction parallel to the normal axis, ΔE is defined as a negative value.

[0180] The reflective element carrier can further include an opposite portion arranged between the outer diameter surface and the opposite surface, and the covering portion and the opposite portion overlap in the direction parallel to the normal axis. Therefore, the reflective element is embedded and fixed in the reflective element carrier by the covering portion and the opposite portion, and the assembly error between the reflective element and the reflective element carrier can be reduced.

[0181] The reflective element carrier can further include an opposite portion arranged between the outer diameter surface and the opposite surface, and the covering portion and the opposite portion do not overlap in the direction parallel to the normal axis.
