A lens barrel includes a lens barrel surrounding wall and a cover member. The lens barrel surrounding wall surrounds an optical axis. The lens barrel surrounding wall includes a lens element accommodating portion abutted against lens elements. The lens barrel surrounding wall has an object side connecting surface closest to an object side and facing the object side. An inner diameter of the lens element accommodating portion closest to the object side is greater than an inner diameter of the lens element accommodating portion closest to an image side. The cover member has an image side connecting surface facing the image side. The image side connecting surface of the cover member is fixed on the object side connecting surface of the lens barrel surrounding wall, wherein a maximum outer diameter of the cover member is less than or equal to a maximum outer diameter of the lens barrel surrounding wall.

Lens barrel

A spacer assembly suitable of being applied in an optical imaging lens is provided. The spacer assembly includes a front spacer, a rear spacer, and a middle light-shielding sheet. The front spacer, the middle light-shielding sheet, and the rear spacer are sequentially arranged from an object side to an image side. Each of the front spacer and the rear spacer has an object-side mechanical surface facing the object side and an image-side mechanical surface facing the image side. The object-side mechanical surface of the rear spacer bears on the middle light-shielding sheet.

Spacer assembly

An optical lens including a light-shielding sheet and a spacer sequentially arranged along an optical axis from a first side to a second side is provided. No other element is disposed between the light-shielding sheet and the spacer. A second side surface of the light-shielding sheet includes a first surface. A first side surface of the spacer includes an abutting surface and a connecting surface connected to each other, and the connecting surface has a protrusion portion. A cross-sectional line of the abutting surface of the spacer in a radial direction is a straight line and abuts against the first surface of the light-shielding sheet, and an abutment between the abutting surface and the first surface falls on a first reference plane. The light-shielding sheet and a most protruding portion of the protrusion portion are located on a same side of the first reference plane.

Optical lens

A lens barrel, including a barrel wall and a sleeve, is provided. The barrel wall extends from an object side to an image side around an optical axis, and has a lens barrel inner surface facing the optical axis and a lens barrel outer surface facing away from the lens barrel inner surface. The lens barrel outer surface includes a lens barrel object-side surface facing the object side. The sleeve is fixed on the lens barrel outer surface and partially embedded in the barrel wall. The sleeve has an object-side end closest to the object side and an image-side end closest to the image side. The object-side end does not extend beyond the lens barrel object-side surface not covered by the sleeve and closest to the object-side end in a direction parallel to the optical axis.

An optical imaging lens, sequentially including at least one lens element and an optical ring element from an object side to an image side along an optical axis, is provided. The optical ring element is located on a side of the lens element closest to the image side and facing the image side, and has an object-side bearing surface facing the object side and in contact with the closest lens element. The object-side bearing surface has an object-side outer periphery and an object-side inner periphery, and the object-side inner periphery is located between the optical axis and the object-side outer periphery. The object-side bearing surface has at least one groove, and the at least one groove extends to the object-side inner periphery along a radial direction.

Optical imaging lens

A spacer, including a spacer body, a light transmissive film, and a light absorbing film, is provided. The spacer body has an outer side surface, an inner inclined surface, an object side surface, and an image side surface. The object side surface faces an object side and connects the outer side surface with the inner inclined surface. The image side surface faces an image side and connects the outer side surface with the inner inclined surface. The inner inclined surface is located between an optical axis of the spacer and the outer side surface, and includes an inner edge adjacent to the optical axis and an outer edge away from the optical axis. The inner edge forms a light through hole. The light transmissive film and the light absorbing film are disposed on the inner inclined surface. All surfaces facing the optical axis are inclined relative to the optical axis.

Spacer

A lens barrel module is disclosed to include a lens barrel unit and a flow path unit. The lens barrel unit extends along an axis and includes a peripheral wall that surrounds the axis and that has a first end adjacent to an object side of a lens assembly and a second end opposite to the first end and adjacent to an image side of the lens assembly. The peripheral wall defines an accommodation space configured as a series of accommodation sections for receiving the optical members. The flow path unit is formed in the lens barrel module and is in spatial communication with at least two of the accommodation sections. A lens assembly including the lens barrel module is also disclosed.
