Abstract

The invention provides a laser emitting coupling device, a laser emitting and display coupling device, a laser receiving coupling device, a laser receiving and display coupling device and a straight tube type double-tube distance measuring telescope. A beam splitter prism is arranged, the beam splitter prism is installed between the emergent surface of a roof prism in an image inversion prism anda focal plane of an objective lens group and is arranged in a manner of sharing the same optical axis with the image inversion prism. The beam splitter prism comprises a first right-angle prism facingthe objective lens group and a second right-angle prism facing the ocular lens group. The inclined plane of the first right-angle prism is used as a first inclined plane and is attached to the inclined plane, as a second inclined plane, of the second right-angle prism; the first inclined surface is plated with a light-splitting high-reflection film for natural light transmission and laser total reflection; the laser transmitters or the laser receivers are correspondingly arranged on the side portions of the first rectangular prisms, and the distances between the light-emitting points of the laser transmitters and the intersection points of the receiving points of the laser receivers and the corresponding optical axes and the corresponding first inclined planes are equal to the distances between the intersection points and the corresponding focal planes.

Description

technical field

[0001] The invention belongs to the technical field of laser range-finding telescopes, and in particular relates to a laser emitting coupling device, a laser receiving coupling device and straight-tube type binocular range-finding telescopes. Background technique

[0002] The popular civilian binoculars on the market are called prism binoculars, which can be divided into Paul prism binoculars, Abbe prism binoculars and Behan roof prism binoculars according to the characteristics of the rubber prisms used.

[0003] Such as Figure 5 As shown, the Behan roof prism binoculars 200 are also called straight-tube binoculars, and the left and right lens tubes (not shown in the figure) are respectively accommodated in order by an objective lens group 210, a relay prism 220 and an eyepiece. Group 230. Since the incident optical axis and the outgoing optical axis of the relay prism 220 are coaxial, and the objective lens group 210 is coaxial with the corresponding eyep...

Embodiment Construction

[0037] The conception of the present invention, concrete structure and the technical effect that will be described further below in conjunction with accompanying drawing, to fully understand the purpose of the present invention's laser emitting coupling device, laser receiving coupling device and straight tube type binocular ranging telescope, feature and Effect.

[0038]

[0039] figure 1 It is the optical principle block diagram of the straight barrel type binocular ranging telescope in the embodiment of the present invention.

[0040] Such as figure 1 As shown, in this embodiment, the straight-tube binocular ranging telescope 100 is improved on the basis of the existing straight-tube binocular telescope 200, and is used for measuring the distance of a selected object to be measured. The straight barrel binocular ranging telescope 100 includes a right lens barrel part 10, a left lens barrel part 20, a laser emitting coupling device 30, a laser receiving coupling device...
