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： A controllable aperture stop includes a light pass portion, a fixed portion, a driving part and rollable elements. The light pass portion includes movable blades together surrounding a light pass aperture. The fixed portion has shaft structures corresponding to the movable blades. The driving part includes a rotatable element, a magnet and a coil. The rotatable element is for driving the movable blades to rotate relative to the shaft structures to adjust the size of the light pass aperture. The magnet is disposed on the rotatable element. The coil corresponds to the magnet. The magnet and the coil are to drive the rotatable element to rotate around the light pass aperture. The rollable elements are disposed between the fixed portion and the rotatable element and arranged around the light pass aperture, so the rotatable element is rotatable relative to the fixed portion.

摘要： An imaging lens system has an optical axis and an image surface through which the optical axis passes. The imaging lens system includes a plastic lens barrel surrounding the optical axis. The plastic lens barrel includes an image-side portion and an object-side aperture through which the optical axis passes, and the image-side portion is located between the image surface and the object-side aperture. The image-side portion includes a protrusive structure surrounding the optical axis and extending towards the image surface. The protrusive structure has an inner surface facing the optical axis, an outer surface disposed opposite to the inner surface and located farther away from the optical axis than the inner surface and a reflection-reducing surface extending towards the image surface and connected to and located between the inner surface and the outer surface. The protrusive structure includes a reflection-reducing structure disposed on the reflection-reducing surface.

摘要： An imaging lens includes a central optical path, a plurality of lens elements sequentially arranged along the central optical path, a wide-range low reflection layer, and an infrared light reduction layer. The plurality of lens elements include a first lens element. The wide-range low reflection layer is disposed on an object-side surface of the first lens element, and the average reflectance of the wide-range low reflection layer to light with a wavelength ranging from 750 to 1050 nanometers is less than or equal to 0.98%. The infrared light reduction layer is located closer to an image side than the wide-range low reflection layer, and the average reflectance of the infrared light reduction layer to light with a wavelength ranging from 750 to 1050 nanometers is greater than or equal to 50%. The central optical path passes through a paraxial region of the first lens element.

摘要： An imaging lens with an optical axis includes a lens carrier and a variable through hole assembly. The lens carrier is configured for at least one lens element to be disposed therein, and the lens carrier includes a mount structure. The variable through hole assembly includes a plurality of movable blades and a rotatable element. The movable blades movably and together surround the optical axis to form a through hole, and a size of the through hole is variable by movement of the movable blades. The rotatable element is connected to the movable blades, and the rotatable element moves the movable blades to vary the size of the through hole. At least one of the movable blades and the rotatable element of the variable through hole assembly is disposed on the mount structure.

摘要： A light pass aperture module, in order along a central axis, includes a blade assembly and a cap. The blade assembly includes a plurality of blades. The blades form a light pass aperture, and the light pass aperture is variable in size with the central axis as a center. The cap covers the blade assembly. The cap has a through hole, and the through hole is disposed corresponding to the light pass aperture. The cap includes a surface level down structure. The surface level down structure is disposed corresponding to one of the blades, and the surface level down structure is closer to the one blade than the through hole.
