  • Patent number: 10551593
    Abstract: An optical lens including a first lens group and a second lens group is provided. The first lens group is arranged between a magnified side and a minified side. The first lens group includes a lens closest to the magnified side. A refractive power of the lens is negative, and at least one surface of the lens is an aspherical surface. The second lens group is arranged between the first lens group and the minified side. A distance between the first lens group and the second lens group is smaller than 0.7 millimeter. The optical lens is complied with conditions of 0.53<EFL/IH<0.7, FOV?150 degrees, and F?2.8, where EFL is an effective focal length, IH is an image height on an imaging plane at the minified side, FOV is a maximum field of view, and F is f-number.

  • Patent number: 9829677
    Abstract: An optical lens including a first lens group located between a magnified side and a minified side and a second lens group between the first lens group and the minified side is provided. The first lens group has a negative power and includes a first lens. The first lens is a plastic aspheric and meniscus lens. Besides, the first lens has a negative power and a convex surface facing the magnified side. The second lens group has a positive power and includes a second lens, a third lens having a negative power, and a fourth lens. Every two of the second, third, and fourth lenses have an air interval between these lenses. The Abbe number of each of at least three of the lenses is greater than 20. A material of at least one of the lenses is glass. At least one of the lenses is a spherical lens.
