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 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 optical lens assembly includes a lens barrel and an optical lens group. The lens barrel includes a light entering hole, which is configured for allowing a light to enter the lens barrel. The lens barrel accommodates the optical lens group, and an optical axis passes through the optical lens group. The optical lens group includes a plurality of lens elements and at least one light blocking sheet. The light blocking sheet is an opaque sheet-shaped element and surrounds the optical axis to form a light passing hole. The light blocking sheet includes an object-side surface and an image-side surface, and the object-side surface is located more adjacent to the light entering hole than the image-side surface thereto. A first film layer is disposed on the object-side surface.

摘要： An imaging lens assembly includes a lens barrel, optical lens elements, an annular retaining element and a nano-microstructure. The optical lens elements include at least one optical lens element disposed in the lens barrel. The annular retaining element is physically contacted with the optical lens element, and the annular retaining element includes an object-side surface, an image-side surface, an outer diameter surface and a light-through hole. The outer diameter surface is connected to the object-side surface and the image-side surface. The light-through hole is formed by gradually tapering from the object-side surface and the image-side surface towards the optical axis. The nano-microstructure has a plurality of irregular ridged convexes. The nano-microstructure is located between a lens barrel area defined via the lens barrel and a lens element area defined via the optical lens element on a direction vertical to the optical axis.
