摘要： An imaging lens module includes a lens element having an optical axis, a lens carrier and a variable through hole assembly. The lens carrier accommodates the lens element and sequentially includes an object-side portion, an image-side portion and a tubular portion. The object-side portion configured for light entering the imaging lens module forms a minimum opening of the lens carrier. The variable through hole assembly is disposed on the object-side portion and includes rotatable blades rotatably disposed about the optical axis and configured to form a through hole with a variable size. Moreover, the object-side portion further has a guiding structure guiding the movement of the rotatable blades and located further away from the optical axis than the minimum opening. Moreover, the object-side portion and the image-side portion form an air sleeve therebetween, and the air sleeve is located further away from the optical axis than the tubular portion.

摘要： This disclosure provides a lens assembly that has an optical path and includes a lens element and a light-blocking membrane layer. The lens element has an optical portion, and the optical path passes through the optical portion. The light-blocking membrane layer is coated on the lens element and adjacent to the optical portion. The light-blocking membrane layer has a distal side and a proximal side that is located closer to the optical portion than the distal side. The proximal side includes two extension structures and a recessed structure. Each of the extension structures extends along a direction away from the distal side, and the extension structures are not overlapped with each other in a direction in parallel with the optical path. The recessed structure is connected to the extension structures and recessed along a direction towards the distal side.

摘要： An imaging lens assembly module includes a lens barrel, a catadioptric lens assembly, an imaging lens assembly, a first fixing element and a second fixing element. The lens barrel has a first relying surface and a second relying surface, which face towards an object side of the imaging lens assembly module. The catadioptric lens assembly relies on the first relying surface. The imaging lens assembly is disposed on an image side of the catadioptric lens assembly, and relies on the second relying surface. The first fixing element is for fixing the catadioptric lens assembly to the lens barrel. The second fixing element is for fixing the imaging lens assembly to the lens barrel. The catadioptric lens assembly is for processing at least twice internal reflections of an image light in the imaging lens assembly module, and for providing optical refractive power.

摘要： A photographing module includes a lens assembly, a reflection element, an image sensor, and lens element, reflection element and image sensor driving modules. An axial voice coil motor of the lens element driving module moves the lens assembly along a lens optical axis. A rotating connection part and a curved recess structure are disposed between a holder and a carrier movable relative to the holder. A lateral voice coil motor of the reflection element driving module drives the carrier carrying the reflection element to rotate around an axis passing through the rotating connection part. A plurality of rollable elements are located between and in contact with the fixed member and the movable plate. A lateral voice coil motor of the image sensor driving module drives the movable plate carrying the image sensor to move based on a dynamic axis orthogonal to the lens optical axis.

摘要： An imaging lens system includes a lens barrel element and an imaging lens assembly disposed on the lens barrel element and including a first imaging lens element, a spacer element and a second imaging lens element. The spacer element has a second object-side contact surface corresponding to a first image-side contact surface of the first imaging lens element. The second imaging lens element has a third object-side contact surface corresponding to a second image-side contact surface of the spacer element. The lens barrel element and the spacer element form a buffer structure closer to an optical axis than the first image-side contact surface and including a first gap and a second gap located closer to the optical axis than the first gap. The first gap overlaps the third object-side contact surface in a direction parallel to the optical axis. A step difference is between the first and second gaps.
