[0046] The present disclosure provides an imaging lens arrangement comprising an optical plastic element. The optical plastic element comprises an incidence surface, an exit surface, and at least one connecting surface. Imaging light enters the optical plastic element through the incidence surface and exits the optical plastic element through the exit surface. The connecting surface is used to connect the incidence surface and the exit surface, the connecting surface comprising a sprue, a divergent nozzle surface, and a gate remnant. The sprue is located on the connecting surface and is raised relative to an adjacent section of the connecting surface. The divergent nozzle surface is connected to the sprue and the adjacent section, and the divergent nozzle surface diverges from the sprue in a direction of the adjacent section.The gate remnant is located on a surface of the sprue remnant, with one contour of the gate remnant being linear and the gate remnant extending over the surface of the sprue remnant. When projected along a direction in a front view of the adjacent section of the joint surface, if one projection surface of the divergent nozzle surface is As and one projection surface of the sprue remnant is Ag, the following condition is satisfied: 0.08 ≤ As / Ag ≤ 0.68.

[0047] Furthermore, the optical plastic element can include a reflective surface. The imaging light can change direction through the reflective surface, and the connecting surface can link the incident surface, the reflective surface, and the exit surface. Specifically, if the optical plastic element includes the incident surface, the reflective surface, the exit surface, and the connecting surface, the optical plastic element is a plastic prism; if the optical plastic element includes the incident surface, the exit surface, and the connecting surface, the optical plastic element is a plastic lens element.

[0048] Furthermore, as the surface precision requirements of the optical plastic element increase, a large sprue area is necessary to improve part quality. The sprue is the cut mark of the injection molding channel and can also be referred to as the flow mark, but this is not the only possible function. The area surrounding the conventional sprue has vertical surfaces, which is not advantageous for light-blocking processes, and the large sprue area presents problems such as an uneven cut surface and high convexity, easily leading to stray light. Therefore, the imaging lens arrangement of the present disclosure, which features a divergent nozzle surface, is advantageous for subsequent light-blocking processes such as laser roughening, coating, coloring, and other additional procedures, thereby reducing the stray light generated around the sprue.Furthermore, the divergent nozzle area has the effect of adjusting the injection rate, which is advantageous for increasing injection molding quality. The appropriate area ratio is beneficial for achieving a balance between part quality and imaging quality. Moreover, the gate residue of the imaging lens arrangement of this disclosure is a mark created by cutting the injection port, which is the common point where the two cutting devices meet in the closed state. This is advantageous for improving the flatness and increasing the cutting efficiency of the injection port. The gate residue and the adjacent sprue residue appear different. In particular, they can be distinguished by their surface properties, such as gloss, color, and roughness. Furthermore, the projection area can be calculated by image recognition.Since the surface properties and angles of inclination between the sprue, the divergent nozzle surface, and the interface differ, both gloss and color make a difference. Therefore, the area can be calculated, but the calculation method is not limited to this; the area can also be calculated by measuring the surface contour.

[0049] When projecting along the direction in the front view of the adjacent section of the joining surface, if the projection area of ​​the adjacent section is Ac, the projection area of ​​the divergent nozzle surface is As, and the projection area of ​​the sprue residue is Ag, the following condition can be met: 0.48 ≤ (As+Ag) / Ac ≤ 3.8. Therefore, it is advantageous to improve part quality by considering the large area fraction of the sprue residue and the divergent nozzle surface. Furthermore, the following conditions can be met: 0.16 ≤ As / Ag ≤ 0.56; and 0.51 ≤ (As+Ag) / Ac ≤ 2.3.

[0050] The divergent nozzle surface can be arranged around the sprue. This prevents stray light from forming around the sprue.

[0051] If the angle between the divergent nozzle surface and the adjacent section is θs, the following condition can be met: 105 degrees ≤ θs ≤ 160 degrees. This is advantageous for the additional method of light blocking of the divergent nozzle surface. Furthermore, the following condition can be met: 120 degrees ≤ θs ≤ 150 degrees.

[0052] The imaging lens assembly defines an optical axis, and if the distance along the optical axis between the incidence and exit surfaces is Dio, and the perpendicular distance between the surface of the sprue and the optical axis is Dg, the following condition can be met: 0.1 ≤ Dg / Dio ≤ 2.1. Therefore, for the miniature design of the imaging lens assembly, it is advantageous if the sprue of the optical plastic element is located close to the optical axis, and the longer distance along the optical axis is advantageous for the telephoto lens assembly. Furthermore, the following condition can be met: 0.1 ≤ Dg / Dio ≤ 0.7.

[0053] The joining surface can further include a multitude of irregular depressions, and these irregular depressions are located at least on the surface of the sprue. Therefore, the surface of the sprue can be roughened by the laser process. Most of the irregular depressions have a width between 1 µm and 100 µm, but this is not the limit. A minority of irregular depressions may be located near the laser path, allowing these irregular depressions to be combined to create wider depressions, which is advantageous for dispersing stray light.

[0054] Furthermore, the arrangement of the irregular depressions can extend from the surface of the sprue remnant to the divergent nozzle surface. This prevents the scattered light from being reflected around the sprue remnant.

[0055] The optical plastic element can further include a light-blocking layer to prevent light from passing through it, and the light-blocking layer is located at least at the sprue and the divergent nozzle surface. This is advantageous for reducing reflection, the sprue, and the scattered light generated around the sprue. Specifically, the light-blocking layer can be, but is not limited to, a dark resin coating, a light-curing coating, a metal oxide coating, etc. The light-blocking layer can also be located at least at the incidence surface, the exit surface, and the adjacent section. Furthermore, a light-transmitting aperture can be formed by the pattern of the light-blocking layer with a serrated profile.

[0056] One form of gate remnant can be a polygon with at least five vertices. The polygon has multiple vertices, and the gate remnant is a connecting line between any two vertices, which are not adjacent. Therefore, the gate remnant is the connecting line between two non-adjacent vertices, which is advantageous for improving the cutting quality of the injection molding channel. Furthermore, the polygonal gate remnant is advantageous for image capture and light blocking. In particular, some of the polygon's vertices can be parallel to surfaces with optical functions, such as the incident, exit, and reflected surfaces, which is also beneficial for improving injection molding quality.

[0057] The present disclosure provides an imaging lens arrangement that defines an optical axis and includes an optical plastic element. The optical plastic element comprises an incidence surface, an exit surface, and at least one connecting surface. Imaging light enters the optical plastic element through the incidence surface and exits the optical plastic element through the exit surface. The connecting surface is used to connect the incidence surface and the exit surface, the connecting surface comprising a sprue, a divergent nozzle surface, and a gate remnant. The sprue is located on the connecting surface and is raised relative to an adjacent section of the connecting surface.The divergent nozzle surface is connected to the sprue and the adjacent section, and the divergent nozzle surface diverges from the sprue in one direction of the adjacent section. The gate is located on a surface of the sprue, with one contour of the gate being linear and extending across the surface of the sprue. If the height of the sprue relative to the adjacent section is Hs, and the perpendicular distance between the surface of the sprue and the optical axis is Dg, the following condition is met: 0.02 ≤ Hs / Dg ≤ 0.12. Therefore, the optical surface can be avoided by cutting the injection port with the appropriate height ratio, and the miniature design of the imaging lens assembly can be achieved.

[0058] Furthermore, the optical plastic element can include a reflective surface. The imaging light can change direction through the reflective surface, and the connecting surface can link the incident surface, the reflective surface, and the exit surface. Specifically, if the optical plastic element includes the incident surface, the reflective surface, the exit surface, and the connecting surface, the optical plastic element is a plastic prism; if the optical plastic element includes the incident surface, the exit surface, and the connecting surface, the optical plastic element is a plastic lens element.

[0059] Furthermore, as the surface precision requirements of the optical plastic element increase, a large sprue area is necessary to improve part quality. The sprue is the cut mark of the injection molding channel and can also be referred to as the flow mark, but this is not the only possible function. The area surrounding the conventional sprue has vertical surfaces, which is not advantageous for light-blocking processes, and the large sprue area presents problems such as an uneven cut surface and high convexity, easily leading to stray light. Therefore, the imaging lens arrangement of the present disclosure, which features a divergent nozzle surface, is advantageous for subsequent light-blocking processes such as laser roughening, coating, coloring, and other additional procedures, thereby reducing the stray light generated around the sprue.Furthermore, the divergent nozzle area has the effect of adjusting the injection rate, which is advantageous for increasing injection molding quality. In addition, the gate residue of the imaging lens arrangement of this disclosure is a mark created by cutting the injection port, which is the common point where the two cutting devices meet in the closed state. This is advantageous for improving the flatness and increasing the cutting efficiency of the injection port. The gate residue and the adjacent sprue residue appear different. In particular, they can be distinguished by their surface properties, such as gloss, color, and roughness.

[0060] If the height of the sprue remnant relative to the adjacent section Hs is , the following condition can be met: 0.08 mm ≤ Hs ≤ 0.68 mm. Furthermore, the following condition can be met: 0.12 mm ≤ Hs ≤ 0.68 mm. Furthermore, the following condition can be met: 0.14 mm ≤ Hs ≤ 0.68 mm.

[0061] The divergent nozzle surface can be arranged around the sprue. This prevents stray light from forming around the sprue.

[0062] If the angle between the divergent nozzle surface and the adjacent section is θs, the following condition can be met: 105 degrees ≤ θs ≤ 160 degrees. This is advantageous for the additional method of light blocking of the divergent nozzle surface. Furthermore, the following condition can be met: 120 degrees ≤ θs ≤ 150 degrees.

[0063] If the optical axis distance between the incidence and exit surfaces is Dio, and the perpendicular distance between the surface of the sprue and the optical axis is Dg, the following condition can be met: 0.1 ≤ Dg / Dio ≤ 2.1. Therefore, for the miniature design of the imaging lens assembly, it is advantageous if the sprue of the optical plastic element is located close to the optical axis, and the longer optical axis distance is advantageous for the telephoto lens assembly. Furthermore, the following condition can be met: 0.1 ≤ Dg / Dio ≤ 0.7.

[0064] The interface can further include a multitude of irregular depressions, and these irregular depressions are located at least on the surface of the sprue. Therefore, the surface of the sprue can be roughened by the laser process. Most of the irregular depressions have a width between 1 µm and 100 µm, which is advantageous for dispersing the stray light.

[0065] Furthermore, the arrangement of irregular depressions can extend from the surface of the sprue to the divergent nozzle surface. This allows the scattered light to be dispersed, preventing it from being reflected around the sprue.

[0066] The optical plastic element can further include a light-blocking layer to prevent light from passing through it, and the light-blocking layer is located at least at the sprue and the divergent nozzle surface. This is advantageous for reducing reflection, the sprue, and the scattered light generated around the sprue. Specifically, the light-blocking layer can be, but is not limited to, a dark resin coating, a light-curing coating, a metal oxide coating, etc. The light-blocking layer can also be located at least at the incidence surface, the exit surface, and the adjacent section. Furthermore, a light-transmitting aperture can be formed by the pattern of the light-blocking layer with a serrated profile.

[0067] One form of gate remnant can be a polygon with at least five vertices. The polygon has multiple vertices, and the gate remnant is a connecting line between any two vertices, which are not adjacent. Therefore, the gate remnant is the connecting line between two non-adjacent vertices, which is advantageous for improving the cutting quality of the injection molding channel. Furthermore, the polygonal gate remnant is advantageous for image capture and light blocking. In particular, some of the polygon's vertices can be parallel to surfaces with optical functions, such as the incident, exit, and reflected surfaces, which is also beneficial for improving injection molding quality.
