    摘要: A fixed focal length 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 fixed focal length lens satisfies F/H>0.52, where F is an effective focal length of the fixed focal length, and H is an image height.

    摘要: A fixed-focus lens disposed between an enlarged side and a reduced side is provided. An f-number of the fixed-focus lens is smaller than or equal to 2. The fixed-focus lens includes a first lens group and a second lens group. The first lens group includes a first lens, wherein the first lens is an aspheric lens. The second lens group, disposed between the first lens group and the reduced side, has a positive dioptre. The second lens group includes a second lens, wherein the second lens is an aspheric lens. The fixed-focus lens focuses by moving the first and the second lens group and satisfies 0.1

    摘要: An optical element is provided in the present invention, which comprises an element body and a plurality of microlens elements. The element body has a first surface disposed thereon. The plural microlens elements are arranged two-dimensionally on the first surface. The size and shape for each microlens elements may be different from each other and the arrangement for the plural microlens elements on the first surface may be random and arbitrary so that the optical element of the present invention are capable of performing light diffusion and light-redirecting effects without generating interference fringes.
