[0046] Preferably, referring to Figure 1 , according to some embodiments of the present utility model, a first mounting seat 110 and a second mounting seat 120 are respectively arranged on both sides of the upper end surface of the experimental platform 100. The rotation module includes a base 160, a swing arm 170, and a connecting bracket 180. A vertically extending rotating shaft 161 is arranged in the middle of the base 160. The top of the rotating shaft 161 is fixedly connected to the bottom of the experimental platform 100 near the second mounting seat 120.

[0049] It can be understood that in optical physics experiments, the experiments of measuring the radius of curvature with Newton's rings, measuring the optical rotation rate of a liquid, measuring the refractive index of a liquid, and grating diffraction experiment all have similar optical paths, and their light sources all come from a sodium lamp or natural light. Therefore, the optical modules required for the above four experiments can be applied to the same experimental platform 100.

[0050] Specifically, referring to Figure 2 , according to some embodiments of the present invention, when performing the experiment of measuring the radius of curvature with Newton's rings, the beam splitter assembly includes a Newton's rings lens 310 and a Newton's rings observation objective lens 320. The Newton's rings lens 310 is installed on the first mounting seat 110, and the Newton's rings observation objective lens 320 is installed on the second mounting seat 120.

[0051] It can be understood that in the experiment of measuring the radius of curvature with Newton's rings, the light emitted by the light source module first shoots towards the Newton's rings observation objective lens 320. The Newton's rings observation objective lens 320 is integrated with a beam splitter to shoot the light towards the Newton's rings lens 310. The Newton's rings lens 310 is integrated with a reflecting mirror to reflect the light back to the Newton's rings observation objective lens 320. Finally, the light shoots towards the eyepiece 200 and is focused on the lens of the CCD camera, thereby collecting an image.

[0052] It should be noted that in the experiment of measuring the radius of curvature with Newton's rings, the Newton's rings lens 310 installed on the first mounting seat 110 can move left and right under the drive of the X-axis movement module, or move up and down under the drive of the Z-axis movement module, so that different-order dark rings on the Newton's rings lens 310 can be aligned with the eyepiece 200; the Newton's rings observation objective lens 320 installed on the second mounting seat 120 can move back and forth under the drive of the Y-axis movement module, so that the focal point of the lens group composed of the Newton's rings observation objective lens 320 and the eyepiece 200 is located on the Newton's rings lens 310; the displacement amounts of the X-axis movement module, the Y-axis movement module, and the Z-axis movement module are controlled and collected through the control display module, and the distance between different-order Newton's rings is calculated through data analysis.

[0053] Specifically, referring to Figure 3 and Figure 4, According to some embodiments of the present utility model, when conducting a liquid optical rotation rate measurement experiment, the spectroscope assembly includes a polarizer 410 and a rotation observation objective lens 420. The polarizer 410 is installed on the first mounting base 110, and the rotation observation objective lens 420 is installed on the second mounting base 120. A solution chamber 421 for installing an optical rotation tube is provided inside the rotation observation objective lens 420. Both ends of the solution chamber 421 are provided with light passing holes, and a convex lens group 422 is provided at the light passing holes.

The stepping motor is connected to the analyzer 424 and drives the analyzer 424 to rotate.

[0054] It can be understood that in the liquid optical rotation rate measurement experiment, the optical rotation tube filled with the liquid to be measured is installed into the solution chamber 421. The light emitted by the light source module first passes through the spectroscope lens 423 and the convex lens group 422 and is projected onto the polarizer 410, and then reflected towards the analyzer 424. After passing through the optical rotation tube and the convex lens group 422, it finally projects onto the eyepiece 200 and is focused on the lens of the CCD camera, so as to collect images. By controlling the rotation of the stepping motor to drive the rotation of the analyzer 424, and collecting the pulse number of the stepping motor through the control and display module, it is converted into the rotation angle of the analyzer 424 and data analysis is carried out.

[0055] It should be noted that in the liquid optical rotation rate measurement experiment, the polarizer 410 installed on the first mounting base 110 can move in the left-right direction under the drive of the X-axis movement module, or move in the up-down direction under the drive of the Z-axis movement module, so that the polarizer 410 can be aligned with the rotation observation objective lens 420; the rotation observation objective lens 420 installed on the second mounting base 120 can move in the front-back direction under the drive of the Y-axis movement module, so that the focal point of the lens group composed of the rotation observation objective lens 420 and the eyepiece 200 is located in the optical rotation tube.

[0056] Specifically, referring to Figure 5 , According to some embodiments of the present utility model, when conducting a liquid refractive index experiment, the spectroscope assembly includes a refractive mirror base 500. The refractive mirror base 500 is installed on the second mounting base 120. An inclined drip cover plate 510 is provided at one end of the refractive mirror base 500 away from the eyepiece 200, and a prism group is provided inside the refractive mirror base 500.

[0057] It can be understood that in the liquid refractive index experiment, the liquid to be measured is dropped on the liquid dropping cover plate 510, and the light emitted by the light source module enters from the liquid dropping cover plate 510, passes through the prism group, then shoots towards the eyepiece 200 and is focused on the lens of the CCD camera, so as to collect images, and the control display module is used to collect data and perform data analysis, so as to identify the refractive index dividing line and calculate the refractive index.

[0058] It should be noted that in the liquid refractive index experiment, the refractive index mirror base 500 installed on the second mounting seat 120 can move in the front-back direction under the drive of the Y-axis movement module, so that the focal point of the lens group composed of the refractive index mirror base 500 and the eyepiece 200 is at infinity.

[0059] Specifically, referring to Figure 6 , according to some embodiments of the present invention, when performing the grating diffraction experiment, the spectroscope assembly includes a grating observation objective lens 600 and a grating. The grating observation objective lens 600 is installed on the first mounting seat 110, and the grating is installed on the second mounting seat 120.

[0060] It can be understood that in the grating diffraction experiment, the light emitted by the light source module enters from the grating observation objective lens 600, then shoots towards the grating, and finally shoots towards the eyepiece 200 and is focused on the lens of the CCD camera, so as to collect images. It should be noted that the eyepiece 200 is driven to rotate by the rotation module to observe the light diffracted by the grating, the angle sensor can detect the rotation angle, and the control display module is used to collect data and perform data analysis.

[0061] Preferably, according to some embodiments of the present invention, the light source module includes a sodium lamp, a transformer and an external power supply. The input end of the transformer is electrically connected to the external power supply, and the output end of the transformer is electrically connected to the sodium lamp.

[0062] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
