摘要： A photographing optical lens assembly includes five lens elements with refractive power, in order from an object side to an image side. The first lens element with refractive power has a convex object-side surface. The second lens element with positive refractive power has an object-side surface and an image-side surface both being aspheric. The third lens element has positive refractive power. The fourth lens element with refractive power has a concave object-side surface. The fifth lens element with refractive power has an object-side surface and a concave image-side surface with at least one inflection point, both the object-side surface and the image-side surface being aspheric.

摘要： An imaging lens assembly includes a plastic barrel and an optical element set. The optical element set includes an optical lens element, a light blocking sheet and a light-shielding layer. At least one surface of an object-side peripheral surface and an image-side peripheral surface of the optical lens element includes an annular side wall. An annular abutting surface of the light blocking sheet and the annular side wall of the optical lens element are disposed correspondingly to each other. The light-shielding layer surrounds a central opening of the light blocking sheet and includes an annular concave-curved portion. The annular concave-curved portion is for retaining the light blocking sheet, so that there is no relative displacement in a direction parallel to an optical axis between the annular abutting surface of the light blocking sheet and the annular side wall of the optical lens element.

摘要： An imaging lens assembly includes a first optical element and a low-reflection layer. The first optical element has a central opening, and includes a first surface, a second surface and a first outer diameter surface. The first outer diameter surface is connected to the first surface and the second surface. The low-reflection layer is located on at least one of the first surface and the second surface, and includes a carbon black layer, a nano-microstructure and a coating layer. The nano-microstructure is directly contacted with and connected to the carbon black layer, and the nano-microstructure is farther from the first optical element than the carbon black layer from the first optical element. The coating layer is directly contacted with and connected to the nano-microstructure, and the coating layer is farther from the first optical element than the nano-microstructure from the first optical element.

摘要： An imaging optical element set has an optical axis, and includes an object-side lens element, an image-side lens element and a light blocking sheet. The light blocking sheet is interposed between the object-side lens element and the image-side lens element, and includes an object-side outer surface, an image-side outer surface, an outer diameter portion, an inner diameter portion and a height compensation structure. The image-side outer surface is opposite to the object-side outer surface. The outer diameter portion has an outer diameter surface connected to the object-side outer surface and the image-side outer surface. The inner diameter portion has an inner diameter surface connected to the object-side outer surface and the image-side outer surface. The height compensation structure is in full circle form, and is for adjusting a height difference between the inner diameter surface and the outer diameter surface along a direction parallel to the optical axis.
