Description

Technical Field

[0001] This application relates to the field of pentaprism equipment technology, and more specifically, to a depolarizing pentaprism. Background Technology

[0002] A pentagonal prism is one of the beam deflectors for a fixed angle. It has two uses: first, regardless of the angle of incidence on the first face, the outgoing light deflects the incident light at a certain angle; second, unlike a right-angle prism, the image it forms has neither rotation nor specular reflection. Pentagonal prisms are commonly used in camera viewfinders, image observation systems, or measuring instruments. Depolarized light refers to the process of converting light waves with polarization characteristics into an unpolarized state.

[0003] Most depolarizing pentagonal prisms on the market currently lack a device for adjusting the prism angle. For example, Chinese patent (authorization announcement number CN205643757U) discloses a depolarizing pentagonal prism comprising a pentagonal prism body and a wedge. The pentagonal prism body is connected to the longest hypotenuse of the wedge via an inclined surface adjacent to the right-angle face. The pentagonal prism body and the wedge are made of the same substrate material. A depolarizing dielectric film layer and an adhesive layer are provided between the mating surfaces of the pentagonal prism body and the wedge. The depolarizing dielectric film layer is deposited on the pentagonal prism body, and the adhesive layer is bonded between the depolarizing dielectric film layer and the wedge. This invention overcomes the shortcomings of commonly used metal depolarizing films in existing pentagonal prisms, such as poor depolarizing effect, short service life, high design and production control difficulty, poor compatibility with adhesives, and poor repeatability and stability. It has the advantages of good depolarizing effect, good compatibility with various adhesives, low difficulty in precise design and production control, and high repeatability and stability.

[0004] Regarding the aforementioned technologies, the inventors believe that it is difficult for experimenters to achieve precise experimental measurement angles by manually adjusting the mirror surface of the depolarizing pentagonal prism. Furthermore, it cannot intuitively demonstrate the relationship between the angles of the incident and reflected rays, resulting in poor experimental stability, measurement errors, and affecting the measurement of the depolarization effect. Utility Model Content

[0005] To address the aforementioned issues, this application provides a depolarizing pentagonal prism.

[0006] The depolarizing pentagonal prism provided in this application adopts the following technical solution:

[0007] A depolarizing pentagonal prism includes a mounting base. A support rod is fixedly connected to the upper surface of the mounting base. A connecting seat is fixedly connected to the top of the support rod. A mounting box is fixedly connected to the upper surface of the connecting seat. A cylinder and a motor are fixedly connected inside the mounting box. Four sets of cylinders are respectively installed at the four vertices of the mounting box. Each cylinder's output end is movably connected to a telescopic rod. A fixing plate is fixedly installed at the other end of the telescopic rod. A connecting hole is opened inside the fixing plate. A rotating rod is provided at the output end of the motor. The rotating rod extends through the connecting hole to the outside of the fixing plate. A mounting rod is fixedly connected to the side of the fixing plate away from the mounting box. Two sets of mounting rods are provided. A suction cup is fixedly connected to the rotating rod. A mirror body is provided on the outside of the suction cup.

[0008] Furthermore, a measuring plate is provided at the bottom of the mounting base.

[0009] The above technical solution allows the incident light to be reflected onto the measuring plate through the mirror, making it easier for experimenters to understand the experimental data and promptly detect the depolarization effect.

[0010] Furthermore, the measuring plate is L-shaped, and the surface of the measuring plate is provided with scale marks.

[0011] With the above technical solution, the measuring plate is set in an L-shape, which not only allows it to receive incident light in the horizontal direction, but also to measure the projection distance of incident light in the vertical direction. The projection distance can be accurately measured by the scale marks set on the measuring plate, which facilitates the analysis and judgment of the measurement results by the experimental personnel.

[0012] Furthermore, a control panel is fixedly connected to the outer side of the support rod, and the control panel is electrically connected to the cylinder and the motor.

[0013] The above technical solution utilizes the electrical connection between the control panel and the cylinder and motor, allowing experimenters to easily control the cylinder and motor through the control panel.

[0014] Furthermore, an adsorption membrane is provided at the axis of the mirror body, and the suction cup is movably connected to the adsorption membrane.

[0015] Through the above technical solution, the adsorption membrane can be replaced at any time at the axis of different experimental mirrors. By utilizing the adsorption effect between the suction cup and the adsorption membrane, the stability between the rotating rod and the mirror can be improved.

[0016] Furthermore, the main material of the mirror body is a mixture of H-K9 L and quartz, and an interference film is coated on its surface.

[0017] Through the above technical solutions, H-K9L has excellent light transmittance and mechanical properties, which can improve the precision of the mirror's depolarization effect. The quartz material can enhance the hardness of the mirror and, to a certain extent, prevent the mirror from being damaged by impacts.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] The experimenter can control the operation of the cylinder and motor through the control panel. First, the cylinder is adjusted to move the telescopic rod installed at its output end to the appropriate measurement position. Then, the motor is adjusted to rotate the rotating rod, causing the mirror to rotate to the appropriate measurement angle. Then, incident light is used to illuminate the mirror. The mechanical rotation and telescopic action can improve the accuracy of the experimental measurement and reduce the experimental error caused by manually adjusting the mirror angle to a certain extent. It also improves the stability of the anti-polarization effect measurement. At the same time, the light reflected by the mirror can be projected onto the measurement plate after exiting the mirror, which facilitates the collection and analysis of the measurement results by the experimenter.

[0028] Example 1:

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a depolarizing pentagonal prism. Please refer to the embodiments therein. Figure 1 The system includes a mounting base 1, a support rod 2 fixedly connected to the upper surface of the mounting base 1, a connecting seat 3 fixedly connected to the top of the support rod 2, a mounting box 4 fixedly connected to the upper surface of the connecting seat 3, a cylinder 5 and a motor 6 fixedly connected inside the mounting box 4, four sets of cylinders 5 respectively installed at the four vertices of the mounting box 4, and telescopic rods 7 movably connected to the output ends of the cylinders 5, with a fixing plate 8 fixedly installed at the other end of the telescopic rods 7, and a connecting hole 9 opened inside the fixing plate 8. A rotating rod 10 is provided at the output end of the motor 6, and the rotating rod 10 extends through the connecting hole 9 to the outside of the fixing plate 8. A mounting rod 11 is fixedly connected to the side of the fixing plate 8 away from the mounting box 4, and two sets of mounting rods 11 are provided. A suction cup 12 is fixedly connected to the rotating rod 10, and a mirror body 13 is provided on the outside of the suction cup 12.

[0031] The bottom of the mounting base 1 is provided with a measuring plate 14. The incident light is reflected by the mirror body 13 onto the measuring plate 14, which makes it convenient for the experimenters to understand the experimental data and detect the depolarization effect in a timely manner.

[0032] The measuring plate 14 is L-shaped, and the surface of the measuring plate 14 is provided with scale marks 15. The L-shaped design of the measuring plate 14 allows it to not only receive incident light in the horizontal direction but also to measure the projection distance of incident light in the vertical direction. The scale marks 15 on the measuring plate 14 can accurately measure the projection distance, which is convenient for the experimenter to analyze and judge the measurement results.

[0033] A control panel 16 is fixedly connected to the outside of the support rod 2. The control panel 16 is electrically connected to the cylinder 5 and the motor 6. By utilizing the electrical connection between the control panel 16 and the cylinder 5 and the motor 6, it is convenient for the experimenter to control the cylinder 5 and the motor 6 through the control panel 16.

[0034] An adsorption membrane is provided at the axis of the mirror body 13. The suction cup 12 is movably connected to the adsorption membrane. The adsorption membrane can be replaced at any time to different experimental mirror bodies 13. The adsorption effect between the suction cup 12 and the adsorption membrane can improve the stability between the rotating rod 10 and the mirror body 13.

[0035] The main material of the mirror body 13 is a mixture of H-K9L and quartz, and an interference film is coated on its surface. H-K9L has excellent light transmission and mechanical properties, which can improve the precision of the polarization removal effect of the mirror body 13. The quartz material can enhance the hardness of the mirror body 13 and prevent the mirror surface from being damaged by bumps to a certain extent.

[0036] The implementation principle of the depolarizing pentagonal prism in this application embodiment is as follows: The experimenter can control the operation of the cylinder 5 and the motor 6 through the control panel 16. First, the cylinder 5 is controlled to move the telescopic rod 7 installed at its output end to a suitable measurement position. Then, the motor 6 is controlled to rotate the rotating rod 10 to rotate the mirror body 13 to a suitable measurement angle. Then, the incident light is used to illuminate the mirror body 13. The mechanical rotation and mechanical telescopic action can improve the accuracy of the experimental measurement and reduce the experimental error caused by manually adjusting the angle of the mirror body 13 to a certain extent, thereby improving the stability of the depolarization effect measurement. At the same time, the light reflected by the mirror body 13 can be projected onto the measuring plate 14 after shining out of the mirror body 13, and the measurement data can be obtained through the scale code 15, making the measurement data more intuitive and clear, and facilitating the experimenter to collect and analyze the measurement results.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
