摘要： A zoom lens includes, in order from an object side to an image side, a first lens unit having negative refractive power, and a plurality of subsequent lens units. The zoom lens further includes an aperture stop. For zooming, the first lens unit is fixed, and the plurality of subsequent lens units move to change a distance between adjacent lens units. Predetermined inequalities are satisfied.

摘要： An imaging lens assembly includes a plastic barrel and an imaging lens set. The plastic barrel includes an object-side aperture and a first annular surface. The imaging lens set includes a plurality of optical elements, wherein at least one of the optical elements is a plastic lens element, and the plastic lens element includes an effective optical portion, a peripheral portion, a second annular surface, and an object-side connecting surface. The peripheral portion is formed around the effective optical portion. The second annular surface is formed on an object-side surface of the plastic lens element and surrounds the effective optical portion. The object-side connecting surface is formed on the object-side surface of the plastic lens element and surrounds the effective optical portion, and the object-side connecting surface is connected with one of the optical elements disposed on an object side of the plastic lens element.

摘要： A four-piece optical image capturing system. In order from an object side to an image side, the optical image capturing system along the optical axis includes a first lens with positive refractive power; a second lens with refractive power; a third lens with refractive power; and a fourth lens with refractive power; and at least one of the image-side surface and object-side surface of each of the four lenses are aspheric. The optical image capturing system can increase aperture value and improve the imagining quality for use in compact cameras.

摘要： An optical imaging lens includes a first lens element, a second lens, an aperture stop, a third lens element and a fourth lens element from an object side to an image side in order along an optical axis, and each lens element has an object-side surface and an image-side surface. An optical axis of the image-side surface of the first lens element is convex and an optical axis of the image-side surface of the fourth lens element is concave. HFOV stands for the half field of view of the entire optical imaging lens and TTL is a distance from the object-side surface of the first lens element to an image plane along the optical axis to satisfy HFOV/TTL≤1.500°/mm.

摘要： A photographing lens assembly includes at least four lens elements that are, in order from an object side to an image side along an optical path, a first lens element, a second lens element, at least one subsequent lens element and a last lens element that is closest to an image surface. Each of the at least four lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. At least one surface among lens surfaces from the image-side surface of the second lens element to the object-side surface of the last lens element is a metasurface having a subwavelength microstructure.

摘要： An image lens assembly includes, in order from an object side to an image side along an optical path, a first lens group, a second lens group, a third lens group and a fourth lens group. A total number of lens elements in the image lens assembly is seven. The first lens group includes a first lens element with positive refractive power and a second lens element with negative refractive power. Each of the second lens group and the third lens group includes at least one lens element. The fourth lens group includes a seventh lens element. When the image lens assembly is focusing or zooming, a relative position between the first lens group and an image surface is fixed, a relative position between the fourth lens group and the image surface is fixed, and the second lens group and the third lens group move along the optical axis.
