The present disclosure provides a glass lens having an optical axis and including an optical portion and a peripheral portion, wherein the optical axis passes through the optical portion and the peripheral portion is distal from the optical axis. The peripheral portion includes an outer diameter surface, a first curved surface, a protruding surface, and a connecting surface. The outer diameter surface defines the outer diameter of the glass lens and extends along the direction of the optical axis. The first curved surface is connected to the outer diameter surface and extends from the outer diameter surface toward the optical axis. The protruding surface is arranged opposite to the first curved surface, and the protruding surface extends and protrudes from the outer diameter surface in a direction away from the first curved surface, and the peripheral portion is smoothly connected from the first curved surface to the protruding surface. The connecting surface gradually approaches the optical axis from the first curved surface toward the direction away from the protruding surface, and the connecting surface is connected to the optical part. On a section parallel to and passing through the optical axis, the radius of curvature of the first curved surface is R, the length of the outer diameter surface is L, and it meets the following conditions: 0.01 R/L 9.85.

By continuously approaching the optical axis from the raised surface toward the first curved surface, the connecting surface controls the flow of glass and prevents defects. The first curved surface and the raised surface are positioned opposite the outer diameter, and the perimeter is smoothly connected from the first curved surface to the raised surface, ensuring optimized outer diameter surface quality. The aforementioned R/L ratio range further ensures the optimal fit between the first curved surface and the raised surface.

Specifically, the outer diameter of a glass lens refers to the outer diameter used for measurement, support, and control, not the maximum diameter range. Furthermore, a glass lens generally refers to a lens primarily composed of minerals. Its composition can be glass materials such as silicon oxide, aluminum oxide, potassium oxide, sodium oxide, and boron oxide. Metals, non-metallic materials, and polymers may be added to impart functional properties such as UV resistance, infrared resistance, and reflection of specific wavelengths, but this is not limited to these.

On a section perpendicular to the optical axis and passing through the outer diameter surface, the true circularity of the outer diameter surface may not be greater than 0.05mm. This prevents eccentricity during assembly.

In the direction perpendicular to the optical axis, the maximum distance between the protruding surface and the outer diameter surface is Pmax, which can meet the following conditions: 0.02mm Pmax 1.0mm. This prevents defects on the raised surface that could affect optical quality.

The peripheral portion may further include an arc end, wherein the arc end is formed on a side of the protruding surface away from the first arc surface, and the curvature radius of the arc end is Rp, which can meet the following conditions: 0.02mm Rp 0.5mm. This allows for controlled outer diameter molding accuracy to maintain industrial applicability and mass production quality.

The connecting surface may include a second curved surface, wherein the second curved surface is adjacent to a side of the first curved surface that is remote from the outer diameter surface and extends from the first curved surface toward the optical axis. Furthermore, on a cross section parallel to and passing through the optical axis, the distance C between an end of the first curved surface that is near the outer diameter surface and an end of the second curved surface that is remote from the outer diameter surface satisfies the following conditions: 0.05 mm C 1.13mm. This facilitates demoulding to ensure and improve the accuracy of the outer diameter surface.

The glass lens may further include a low-reflection surface, wherein the connecting surface may further include a transition surface that smoothly connects the first curved surface and the second curved surface, with the low-reflection surface disposed on the transition surface. This prevents glare caused by light reflecting off the transition surface, thereby reducing the negative impact of surrounding elements on optical quality. Furthermore, the low-reflection surface may be disposed on at least one of the outer diameter surface, the first curved surface, and the protruding surface. This prevents glare caused by light passing through the connecting surface, thereby improving optical performance. Specifically, the low-reflection surface may achieve the aforementioned effect by providing, but is not limited to, a light-shielding layer, an anti-reflection layer, or an anti-reflection structure.

The glass lens may further include a first platform surface, and the first platform surface is perpendicular to the outer diameter surface, wherein the length of the outer diameter surface in a cross section parallel to and passing through the optical axis is L; the width of the first platform surface in a direction perpendicular to the optical axis is W1, which can meet the following conditions: 0.14 L/W1 3.8. The first mesa surface can improve the glass lens assembly process, thereby increasing yield. Furthermore, the first mesa surface can be disposed on the side of the raised surface facing away from the outer diameter surface, between the raised surface and the outer diameter surface, or on the side of the curved surface facing away from the outer diameter surface, but the above examples are not limited thereto.

The glass lens may further include a second platform surface, wherein the second platform surface is disposed opposite the first platform surface, the first platform surface and the second platform surface are parallel, and the parallelism between the first platform surface and the second platform surface may not exceed 0.05 mm. This ensures its assemblability.

The glass lens may further include a tapered surface, wherein the tapered surface is disposed on a side of the protruding surface away from the outer diameter surface, and the tapered surface extends in a direction away from the protruding surface and close to the optical axis. In a cross section parallel to and passing through the optical axis, the angle between the tapered surface and the outer diameter surface is DOC, which can meet the following conditions: 10 degrees DOC 60 degrees. This allows for the adjustment and control of the glass flow direction, ensuring the formability of the glass lens and improving optical quality.

On a section parallel to and passing through the optical axis, the length of the outer diameter is L, which satisfies the following conditions: 0.03mm L. This ensures the stability of the surrounding area.

The various technical features of the glass lens disclosed above can be combined and configured to achieve corresponding effects.

This disclosure provides an imaging lens comprising the aforementioned glass lens, at least one optical element, and a lens carrier. The optical element is disposed along the optical axis of the glass lens, and the glass lens and the optical element are mounted on the lens carrier. Specifically, the optical element may be, but is not limited to, a light shielding plate, a spacer element, a fixed element, a lens, a reflective element, and the like.

The lens carrier is in physical contact with the outer diameter surface of the glass lens and may include a protrusion-matching structure. The protrusion-matching structure is positioned opposite the protrusion of the glass lens, with a gap formed between the protrusion and the protrusion-matching structure. The physical contact between the lens carrier and the outer diameter surface and the gap between the protrusion and the protrusion prevents skew of the glass lens, thereby ensuring optical quality.

Please refer to Figures 1E and 1F. Figure 1E shows an enlarged partial view of the imaging device 10 according to the first embodiment of Figure 1D, and Figure 1F shows a schematic diagram of the first lens 111 according to the first embodiment of Figure 1D. As shown in Figures 1E and 1F, the first lens 111 has an optical axis X and includes an optical portion 140 and a peripheral portion 150. The optical axis X passes through the optical portion 140, and the peripheral portion 150 is spaced apart from the optical axis X. The peripheral portion 150 includes an outer diameter surface 151, a first curved surface 152, a protruding surface 153, and a connecting surface 154.

Specifically, outer surface 151 defines the outer diameter of first lens 111 and extends along optical axis X. First curved surface 152 is connected to outer surface 151 and extends from outer surface 151 toward optical axis X. Raised surface 153 is disposed opposite outer surface 151 and extends away from first curved surface 152. The peripheral portion 150 smoothly connects from first curved surface 152 to raised surface 153. Connecting surface 154 gradually approaches optical axis X from first curved surface 152 away from raised surface 153 and is connected to optical portion 140.

The connecting surface 154 continuously approaches the optical axis X from the protruding surface 153 toward the first curved surface 152 to control the flow of glass, thereby preventing defects. Furthermore, by arranging the first curved surface 152 and the protruding surface 153 opposite the outer diameter surface 151 and ensuring a smooth connection between the peripheral portion 150 and the first curved surface 152 and the protruding surface 153, the quality of the outer diameter surface 151 is optimized.

Specifically, the outer diameter surface 151 defines the outer diameter of the first lens 111, which refers to the outer diameter size of the first lens 111 used for measurement, support, and control, rather than the maximum diameter range.

The first lens 111 may further include a first platform surface 161 and a second platform surface 162, wherein the first platform surface 161 is perpendicular to the outer diameter surface 151 and may be disposed on a side of the first curved surface 152 away from the outer diameter surface 151, with the lens carrier 130 physically contacting the first platform surface 161. The second platform surface 162 is disposed opposite the first platform surface 161 and is parallel to the second platform surface 162. The parallelism between the first platform surface 161 and the second platform surface 162 may be no greater than 0.05 mm, and the second platform surface 162 is physically contacting the second lens 112. The first platform surface 161 improves the assembly process of the first lens 111 and the stability of the fit between the components. The relative positioning of the first platform surface 161 and the second platform surface 162 ensures assembly performance, thereby improving yield.

As shown in Figure 1F, the connecting surface 154 may include a second curved surface 155 and a transition surface 156.

This facilitates demolding and ensures and improves the precision of the outer diameter surface 151.

The first lens 111 may further include a low-reflection surface 170, disposed between the first curved surface 152 and the transition surface 156. This prevents glare caused by light reflecting off the connecting surface 154 and the transition surface 156, thereby reducing the negative impact of the peripheral portion 150 on optical quality and improving optical performance. In the first embodiment, the low-reflection surface 170 is a light-shielding layer, which is used only to indicate its location and not its actual thickness.

The first lens 111 may further include a tapered surface 180 , disposed on the side of the protruding surface 153 distal from the outer diameter surface 151 . The tapered surface 180 extends away from the protruding surface 153 and toward the optical axis X. This allows for adjustable control of the glass flow direction, ensuring the formability of the first lens 111 and improving optical quality. Furthermore, the tapered surface 180 is in physical contact with the second lens 112 to reduce inter-lens offset, thereby improving stacking quality.

The protrusion-matching structure 131 is positioned opposite the protrusion 153 of the first lens 111, with a gap G1 formed between the protrusion 153 and the protrusion-matching structure 131. The physical contact between the lens carrier 130 and the outer diameter surface 151 and the gap G1 between the protrusion 153 prevents the first lens 111 from tilting, thereby ensuring optical quality.

The second lens 112 may include a protrusion-surface-corresponding structure 132 , wherein the protrusion-surface-corresponding structure 132 is disposed opposite the protrusion surface 153 of the first lens 111 , and a gap G2 is formed between the protrusion surface 153 and the protrusion-surface-corresponding structure 132 .

The peripheral portion 150 may further include an arc end 157 , wherein the arc end 157 is formed on a side of the protruding surface 153 away from the first arc surface 152 , and the arc end 157 may be disposed on a side of the protruding surface 153 facing the protruding surface corresponding structure 132 .

On a section perpendicular to the optical axis X and passing through the outer diameter surface 151, the true circularity of the outer diameter surface 151 may not be greater than 0.05mm. This prevents eccentricity during assembly.
