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 annular optical element having an optical axis includes an outer diameter surface, an inner annular surface, an object-side surface and an image-side surface. The object-side surface includes an annular reflecting surface, an annular auxiliary surface and a connecting surface. The annular reflecting surface is inclined with the optical axis. The annular auxiliary surface is closer to the optical axis than the annular reflecting surface is to the optical axis. The connecting surface is for connecting to an optical element, wherein the connecting surface is closer to the optical axis than the annular auxiliary surface is to the optical axis. The image-side surface is located opposite to the object-side surface and includes an annular optical surface. A V-shaped groove is formed by the annular auxiliary surface and the annular reflecting surface of the object-side surface.

摘要： A camera module includes an imaging lens assembly module and an image sensor. The image sensor is disposed on an image surface of the imaging lens assembly module and includes a photoelectric converting layer, a micro lens arrays layer, a light filtering layer and an anti-reflecting layer. The photoelectric converting layer is for converting a light signal to an electric signal. The micro lens arrays layer is for converging an energy of the imaging light into the photoelectric converting layer. The light filtering layer is for absorbing a light at a certain wavelength region of the imaging light. The anti-reflecting layer is disposed on a surface of at least one of the light filtering layer and the micro lens arrays layer and includes an irregular nano-crystallite structure layer and an optical connecting layer. The optical connecting layer is connected to the irregular nano-crystallite structure layer.

摘要： An imaging lens assembly includes a plastic barrel and a lens set, and the lens set is disposed in the plastic barrel. The plastic barrel includes an object-side outer surface, a first inner surface and a second inner surface. The lens set has an optical axis, and includes, in order from an object side to an image side thereof, at least one plastic lens element and a spacer. A light-absorbing coating is disposed on the plastic lens element. The spacer includes an object-side connecting surface and a relative surface. When the object-side connecting surface is connected with a neighboring object-side optical element, the relative surface is out of touch with the neighboring object-side optical element. There is an overlap between the second inner surface and the relative surface along a direction parallel to the optical axis.
