Problems solved by technology

One is that the space provided by the prism to the display device is narrow, resulting in a small display field of view, only 1 / 3 of the field of view of the other optical path. It can only display simple characters such as a row of four-digit characters, etc., and cannot achieve a large field of view. graphic display
Second, because the spectroscopic film is far away from the normal incidence, the transmittance of the system is less than 35%, the brightness of the displayed image is extremely low, and the product cannot be used during the day
The imaging lens group has narrow space, simple structure, poor imaging quality, and unclear additional graphic information, making it difficult to see characters

Embodiment 1

[0041] see Figure 1 to Figure 5 Shown, a kind of binoculars with digital display laser ranging function, including objective lens assembly, light splitting and image combining prism system and eyepiece assembly, described light splitting and image combining prism system is arranged between objective lens assembly and eyepiece assembly;

[0042] The light-splitting and image-combining prism system includes a roof prism 4 and a compound prism. In the binoculars of the binoculars, the compound prism in one of the tubes is composed of an isosceles prism 2, a right-angle prism A1, and a right-angle prism B 3. Among them, the right-angle prism A1 It has the same shape as rectangular prism B 3 and is symmetrically abutted on the two isosceles surfaces of isosceles prism 2 respectively; wherein the compound prism in the other tube is composed of rectangular prism A1 and rectangular prism 25; wherein the rectangular prism 25 A right-angled surface 26 is longer than the slope of the ri...

Abstract

The invention discloses a binocular telescope capable of digital display and laser range finding. The telescope comprises an object lens assembly, a light splitting and coincidence prism system and anocular lens assembly, the light splitting and coincidence prism system arranged between the object lens assembly and the ocular lens assembly comprises a ridge prism and a composite prism; the composite prism is formed by combining an isosceles prism, a rectangular prism A and a rectangular prism B, and the rectangular prism A and the rectangular prism B are the same in shape and symmetrically abut against two isosceles sides of the isosceles prism respectively. or the composite prism is formed by combining the rectangular prism A with the rectangular prism B, and one right-angle surface of the rectangular prism is greater than the inclined surface of the rectangular prism A, and abuts against the inclined surface of the rectangular prism A. The binocular telescope is capable of observation, laser range finding, as well as displaying characteristics as an optical virtual sight bead and the measurement distance in the field of view.

Description

technical field [0001] The invention relates to a digital display laser ranging binoculars, belonging to the technical field of optical instruments. Background technique [0002] At present, the laser ranging binoculars have the problem that they cannot meet the actual mass production and demand from the perspective of optical and mechanical properties. Products with good performance have complex optical and mechanical structures and difficult processes. Low-end products cannot meet the requirements of actual use due to their poor performance. There are three types of erecting prisms used in laser ranging binoculars: Porro prisms, Schmidt prisms and Abbe prisms. In comparison, the Porro prism with the same material has a slightly smaller field of view and a slightly larger space volume, so the resulting product is relatively bulky. The Schmidt special Han prism is compact in size, but it loses a lot of light energy, and it is difficult to enlarge the aperture. After compo...
