Abstract: An optical lens includes a first lens group with negative refractive power, a second lens group with positive refractive power, and an aperture stop disposed between the first lens group and the second lens group. A total number of lenses in the first lens group is less than three, and a total number of lenses in the second lens group is less than five. The second lens group includes a first lens, a second lens and a third lens arranged in order in a direction away from the aperture stop. Each of the first lens and the second lens is an aspheric lens, and one of the first lens and the second lens has a diffractive optical surface.

Abstract: An optical lens includes five aspheric lenses and an aperture stop. The five aspheric lenses are, arranged in order from a first side to a second side, a first lens, a second lens, a third lens, a fourth lens and a fifth lens, and the aperture stop is disposed between the first lens and the second lens. An image height at the image plane is denoted as H, the image height is equally divided into ten sections to from ten height positions 0.1H, 0.2H, 0.3H, 0.4H, 0.5H, 0.6H, 0.7H, 0.8H, 0.9H and 1H. Chief rays traveling through the optical lens and to the ten height positions respectively form ten angles with respect to a normal of an image plane, and each of the ten angles is smaller than 10 degrees.

Abstract: A zoom lens is provided. The zoom lens includes a first lens group, a second lens group, a third lens group and an aperture stop. The second lens group is disposed between the first lens group and the third lens group. The aperture stop is disposed between the first lens group and the second lens group. When the zoom lens zooms, the aperture stop is fixed without moving and the first lens group correspondingly moves.

Abstract: An optical lens includes a first lens group and a second lens group. The first lens group is disposed between a magnified side and a minified side and has a negative refractive power. The second lens group is disposed between the first lens group and the minified side and has a positive refractive power. The optical lens is capable of forming an image at the magnified side. F/H>0.52, where F is an effective focal length, and H is an image height. A viewing angle is greater than 116.7 degrees.

Abstract: On embodiment of the invention discloses an optical lens including five lens group and an aperture stop. Each lens group includes at least one lens with refractive power, and the aperture stop is fixed in a position between a second lens group and a third lens group. Further, a distance between a first lens group and a fifth lens group remains fixed during zooming or focusing, and respective distances of the second lens group and a fourth lens group relative to the fifth lens group vary during zooming or focusing.
