Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a beam splitting system, which has the advantages of providing a beam splitting system with a simple and compact structure, which can split multiple beams, and solves the problem of cost changes in manufacturing caused by customized prisms. High, a prism is specially customized to be used in conjunction with the Schmidt-Biehan prism system (Paul prism system, Abbe prism system, etc.) to realize the combination (separation) of beams. Such a system structure requires Relatively high, processing also requires special fixtures

Embodiment 1

[0025] see Figure 1-5 , a beam splitting system, comprising an eyepiece observation system 1, a first half pentaprism 2, a photoelectric conversion device 3, a second half pentaprism 4, a branch optical path lens group 5, a display device 6, an objective lens group 7 and a roof prism 8, The right side of the eyepiece observation system 1 is placed with the first half pentaprism 2, the minimum acute angle number in the second half pentaprism 4 is equal to the minimum acute angle number in the first half pentaprism 2, the first half pentaprism 2 The bottom surface is provided with a coating, the first half pentaprism 2 and the second half pentaprism 4 are glass, and the top surface of the second half pentaprism 4 is provided with a coating, the first half pentaprism 2 is inclined, and the second half five The prism 4 is obliquely arranged, and the first half pentaprism 2 is manufactured by fine grinding, the angle of the first half pentaprism 2 is exactly the same as that of th...

Embodiment 2

[0027] see Figure 6-10 , a beam splitting system, the roof prism 8 is located on the upper left side of the first half pentaprism 2, the branch optical path lens group 5 and the display device 6 are obliquely arranged, and the photoelectric conversion device 3 is parallel to the opposite surface of the second half pentaprism 4.

[0028] The optical path in the second embodiment is subdivided into r4 / r5 / r6, Figure 8 , Figure 9 and Figure 10 The optical path diagram of r4 / r5 / r6 in turn, the optical path diagram of r4 / r5 / r6 in the second embodiment is obviously different from the optical path diagram of r1 / r2 / r3 in the first embodiment, the optical path diagram of r4 / r5 / r6 is used to express the implementation In Example 2, the optical path reentry mode of each optical path can be used in combination with each other. Except for the above differences, the second embodiment is the same as the first embodiment.

[0029] To sum up, the beam splitting system traditionally needs...

Abstract

The invention relates to the technical field of prisms, and discloses a light beam separation system. The system comprises an eyepiece observation system, a first half pentaprism, a photoelectric conversion device, a second half pentaprism, a branch optical path lens group, a display device, an objective lens group and a roof prism, wherein the first half pentaprism is placed on the right side ofthe eyepiece observation system, the second half pentaprism is bonded to the bottom of the first half pentaprism, the photoelectric conversion device is located below the second half pentaprism, and the roof prism is located on the upper right portion of the first half pentaprism. The light beam splitting system achieves the purpose of dividing one path of light into two or more paths, and can achieve the purpose that the three paths of light can be coaxial, namely, coaxial light is split out or extra light is supplemented into a main light path; an existing light path beam splitting system onthe market is high in cost and high in universality and machining and assembling difficulty due to the fact that a prism is specially customized; according to the invention, the light splitting of the light path can be achieved only by additionally arranging one half pentaprism, so the structure is simple, and the machining cost is low.

Description

technical field [0001] The invention relates to the technical field of prisms, in particular to a beam splitting system. Background technique [0002] Prisms are polyhedrons made of transparent materials (such as glass and crystal, etc.), and are widely used in optical instruments. Prisms can be divided into several types according to their properties and uses. "Dispersion prism", the more commonly used is the equilateral prism, which changes the direction of light in periscopes, binocular telescopes and other instruments to adjust its imaging position, which is called "total reflection prism", and generally uses right-angle prisms. [0003] According to a spectroscopic prism assembly and a spectroscopic system disclosed in Chinese invention CN 205749884 U, the spectroscopic system can only divide one path of light into two paths, and cannot realize the combination or separation of the third path of light, and its compensation prism is a Customized prisms, custom prisms wil...
