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 and light transmitter module includes a prism holder, a light transmitter, a prism module, a drive circuit board, a shield, and a fixing assembly. The light transmitter is configured to emit or receive a light beam along a light axis. The prism module includes an inclined plane and is disposed within the prism holder with the inclined plane exposed. The drive circuit board is disposed above the inclined plane, and intersects with the light axis at a first angle. The shield is disposed on the drive circuit board. The fixing assembly connects to the prism holder, is configured to fix the drive circuit board, and includes a hole through which the light transmitter is exposed. A binocular capable of measuring distance includes a first optical system and a second optical system. The first optical system or/and the second optical system include the prism and light transmitter module.

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: An ocular structure for observation apparatus includes a first member, a second member and a main body. The first member includes at least one slot and a plurality of first limiting mechanisms. The second member includes at least one slider extending into the slot and a plurality of second limiting mechanisms. The main body includes an ocular lens unit, wherein the first member and the second member are mounted on the main body. The slider is moved in the slot when the first member and the second member are in relative rotation, and the first limiting mechanisms directly or indirectly match the second limiting mechanisms to position the first member with respect to the second member.
