摘要： An optical lens assembly includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens, all of which are arranged in order from an object side to an image side along an optical axis. The first lens is a meniscus lens with positive refractive power. The second lens is with positive refractive power. The third lens is with negative refractive power. The fourth lens is with positive refractive power and includes a convex surface facing the image side. The fifth lens is with negative refractive power and includes a concave surface facing the object side. The sixth lens is with positive refractive power and includes a convex surface facing the image side.

摘要： A lens assembly for display includes a display, a lens assembly, and a prism assembly. The display emits a first light beam. The prism assembly includes a first, second prisms, and an optical multilayer film, wherein the first prism includes a first, second, and third surfaces; the second prism includes a fourth, fifth, sixth, seventh, and eighth surfaces; and the optical multilayer film is disposed between the third and fifth surfaces. A second light beam enters the first prism through the first surface and exits by the second surface. The first light beam exits the lens assembly and enters the second prism through the eighth surface, and exits the first prism by the second surface. The lens assembly and the prism assembly satisfy: 0.80%≤E1/E0≤0.95%; wherein E0 is an energy of the first light beam emitted from the display and E1 is an energy of the first light beam passes through the lens assembly.

摘要： An optical device includes an objective module, a prism module and an ocular module. The prism module includes a first prism, a second prism, a third prism and a first coating. The prism module is disposed between the objective module and the ocular module. A first light beam emitted by an object sequentially passes through the objective module, the prism module and the ocular module. Central axes of the objective module and the ocular module are in parallel without overlapping.

摘要： A range finder includes a prism module and a prism adjusting mechanism. The prism module includes a fixing prism group and a movable prism group, wherein the fixing prism group is adjacent to the movable prism group. The prism adjusting mechanism includes a first adjusting group and a second adjusting group, wherein the first adjusting group includes a first adjusting member and a second adjusting member, and the second adjusting group includes a third adjusting member. The first adjusting member or the second adjusting member is rotated to axially move so that the movable prism group is rotated with respect to the fixing prism group about a first axis, the third adjusting member is rotated to axially move so that the movable prism group is rotated with respect to the fixing prism group about a second axis, and the first axis is perpendicular to the second axis.
