A lens module includes a lens barrel and a first optical lens. The lens barrel includes a first lens chamber and a second lens chamber arranged along an optical axis, wherein an inner edge surface of the lens barrel has an extension portion, the extension portion is located between the first lens chamber and the second lens chamber and defines a light-passing hole, and the first lens chamber communicates with the second lens chamber via the light-passing hole. The first optical lens is disposed in the first lens chamber and has a first optical zone surrounding the optical axis and a first non-optical zone surrounding an outside of the first optical zone, wherein the first non-optical zone includes a first protrusion, and the first protrusion is disposed in the light-passing hole.

Lens module

A lens module includes: a lens barrel including a annular structure, an inner annular surface surrounding the central axis and an outer annular surface opposite to and surrounding the inner annular surface, wherein the inner annular surface forms an accommodating space; an optical lens assembly and an optical filter sequentially disposed in the accommodating space from the object side to the image side; wherein the annular structure is disposed on the inner annular surface and surrounds the central axis, the annular structure includes at least two step portions and at least two bevel portions, all the step portions and the bevel portions are close to the image side, and the optical filter is disposed on the step portions; and the step portions and the bevel portions are alternately disposed along a annular path of the inner annular surface.

An optical element is ring-shaped and has an inner peripheral face. The inner peripheral face is formed with a bumpy section. The bumpy section is formed with a plurality of grooves. The grooves are disposed around an axial direction of the optical element. A rib is formed between any adjacent two of the grooves. Each of the grooves has a fifth end and a sixth end along the axial direction. A width of each of the grooves along a circumferential direction is increasing from the sixth end toward the fifth end so that a third angle between two lateral walls of each of the grooves is larger than 0 degree but smaller than 90 degrees.

Lens mount, optical element, and lens module

A light blocking plate is adapted for being installed on a lens wherein the lens has an optical portion and a positioning portion surrounding the optical portion. The light blocking plate includes an annular body which is formed with a through hole at a central portion thereof. The annular body has a first face and a second face. The annular body has an inner rim and an outer rim. The through hole is defined by the inner rim. One of the first face and the second face is adapted for being disposed on the positioning portion of the lens. The inner rim is formed with a plurality of notches so that the inner rim has a contour which is not smooth circular. Thus, halo disturbance can be reduced.

Light blocking plate and lens assembly including the same

The present invention provides an exhausting structure for lens. The exhausting structure is used for being disposed and fixed between a lens and an optical apparatus. The exhausting structure is formed with an air channel. The air channel has a first opening and a second opening. A projecting outline of the first opening in a projecting direction is separated from a projecting outline of the second opening in the projecting direction. Thereby, the air channel allows air to flow therethrough. Further, an air pressure caused by the change of the temperature in the exhausting structure can be released so as to prevent the air from pressing the lens or apparatus. The exhausting structure can also prevent a light from entering into the base through the air channel.
