    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.

    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 fixed focal imaging lens includes two lens sets and an aperture stop. One of the two lens sets is disposed between a magnified side and the aperture stop. The other one of the two lens sets is disposed between the aperture stop and a minified side. The lens set disposed between the magnified side and the aperture stop includes an aspheric lens and a compound lens, wherein the aspheric lens is a lens closest to the magnified side in the lens set, and the compound lens includes a plurality of lenses combined together. The lens set disposed between the aperture stop and the minified side includes a compound lens and an aspheric lens, wherein the compound lens includes a plurality of lenses combined together, and the aspheric lens is a lens closest to the minified side in the lens set.
