    摘要: A fixed focus image capturing lens, including a first lens group, a second lens group, and an aperture, is provided. The first lens group includes a first lens, a second lens, a third lens, and a fourth lens in sequence from an object side of the fixed focus image capturing lens to an image side thereof. The refractive powers of the first lens, the second lens, and the third lens are all negative. The second lens group includes four lenses having refractive power. The four lenses include a cemented lens. The aperture is disposed between the first lens group and the second lens group.

    摘要: A lens assembly includes a first lens group, a second lens group and an aperture. The first lens group includes two lenses with refractive power. The second lens group with a positive refractive power includes at least two lenses with refractive power. The aperture is disposed between the first lens group and the second lens group. The lens assembly includes 5 to 8 lenses with refractive power. D1 is the diameter of the lens surface of the first lens group farthest from the second lens group. LT is the length on the optical axis of the lens from the lens surface farthest from the imaging plane of the lens assembly to the lens surface closest to the imaging plane of the lens assembly. IMH is the maximum imaging height of lens assembly on the imaging plane, wherein the lens assembly satisfies conditions: 3.5

    摘要: A lens structure includes a lens cone, at least one lens and an acrylate adhesive. The lens cone includes at least one contacting structure. The lens is disposed within the lens cone and abuts against the contacting structure. The acrylate adhesive covers an interface between the lens cone and the lens, wherein a coverage area of the acrylate adhesive accounts for more than 70% of a surface area of a side surface of the lens.

    摘要: A lens including a filter, an aperture stop, and a lens set sequentially arranged along a first direction is provided. The filter includes a central region and a peripheral region. The central region has a first light transmission band for a wavelength range of a visible light and a second light transmission band for a wavelength range of an infrared light. The peripheral region surrounds the central region. The peripheral region has a third light transmission band for the wavelength range of the infrared light and is substantially opaque to the visible light, and an area of one portion of the central region surrounded by the peripheral region is tapered toward the first direction.

    摘要: An optical lens includes a first lens group and a second lens group. The first lens group has at least two lenses that include at least one aspheric lens, the second lens group has at least four lenses that includes at least one aspheric lens, and a total number of lenses with refractive powers in the optical lens is smaller than nine. The first and the second lens groups include a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens in order from the magnified side to the minified side. The first lens to the sixth lens have respective refractive powers of negative, negative, positive, positive, negative and positive.
