    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: A prism module includes a first prism including a first surface, a second surface and a third surface, a roof prism including a roof surface and a fourth surface, a second prism including a fifth surface, a sixth surface and a seventh surface, and a third prism including a light access surface, a first reflecting surface and a second reflecting surface. A light source is disposed above the second prism and adjacent to the first and the roof prisms. A light beam emitted by the light source enters and is reflected by the third prism, enters the second prism through the seventh surface, passes through the sixth surface, enters the first prism through the third surface, and is reflected by the second surface to leave the prism module. The light beam leaving the prism module is parallel to a baseline passing through the first, the second and the fourth surfaces.

    摘要: A rotating shaft mechanism includes a first connecting portion, a second connecting portion, a central shaft rotatably connected to the first connecting portion and the second connecting portion, and an adjusting unit disposed on the central shaft. The adjusting unit includes an adjusting ring disposed around the central shaft, a first washer disposed around the central shaft and configured to generate a force to the first connecting portion or the second connecting portion. A position of the adjusting ring with respect to the central shaft is axially adjustable for adjusting the force so that the first connecting portion or the second connecting portion is rotatable or fixed relative to the central shaft.
