Abstract: A catadioptric optical membrane, which is disposed on a surface of a substrate, includes a reflection membrane and a matting membrane. The reflection membrane is disposed on an effective optical path area of the substrate and includes a reflection metal membrane and a reflection oxidation membrane. The reflection oxidation membrane includes a first reflection oxidation membrane and a second reflection oxidation membrane. The reflection metal membrane is farther away from the substrate than the first reflection oxidation membrane. The second reflection oxidation membrane is farther away from the substrate than the reflection metal membrane. The matting membrane is disposed on a non-effective optical path area of the substrate. The matting membrane includes a deep-color membrane and a first anti-reflection membrane. The deep-color membrane includes a deep-color metal membrane and a deep-color oxidation membrane. The deep-color membrane is farther away from the substrate than the first anti-reflection membrane.

Abstract: A camera module includes an imaging lens assembly and an image sensor. An image is formed on the image sensor via the imaging lens assembly, the image sensor is disposed on an image side of the imaging lens assembly, and the imaging lens assembly includes a lens barrel, a plurality of plastic lens elements and a first light blocking sheet. The plastic lens elements are disposed in the lens barrel. The first light blocking sheet is disposed in the lens barrel and has a non-circular opening. A portion of the image formed via the imaging lens assembly is a defocused image, and a shape of at least one portion of the defocused image is non-circular and corresponding to a shape of the non-circular opening of the first light blocking sheet.

Abstract: An optical lens system includes six lens elements from an object side to an image side, the six lens elements are, in order from the object side to the image side, a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element and a sixth lens element. Each of the six lens elements has an object-side surface towards the object side and an image-side surface towards the image side. The image-side surface of the second lens element is concave in a paraxial region thereof. The third lens element has positive refractive power. The image-side surface of the fourth lens element is concave in a paraxial region thereof. The image-side surface of the sixth lens element includes at least one inflection point.

Abstract: An imaging lens assembly includes three lens elements which are, in order from an object side to an image side along an optical path: a first lens element, a second lens element and a third lens element. Each of the three lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. The object-side surface of the second lens element is concave in a paraxial region thereof. At least one surface of at least one lens element in the imaging lens assembly has at least one inflection point.

CPC classification number: G02B17/0856 , G02B13/0045
Abstract: An imaging system lens assembly includes a first lens group and a second lens group. The first lens group includes a first catadioptric lens element and a second catadioptric lens element, the second lens group includes at least one lens element. Each of an object-side surface and an image-side surface of the first catadioptric lens element and the second catadioptric lens element includes a central region and a peripheral region. The peripheral region of the object-side surface of the first catadioptric lens element includes a first refracting surface. The peripheral region of the image-side surface of the second catadioptric lens element includes a first reflecting surface. The central region of the object-side surface of the first catadioptric lens element includes a second reflecting surface. The central region of the image-side surface of the second catadioptric lens element includes a last refracting surface.
