As Figure 1 and Figure 2 shown, an embodiment of the present application provides a polarizer turntable, including a stage 10, a first connecting member 20 disposed at the first end of the stage 10, and a second connecting member 30 disposed at the second end of the stage 10.

[0021] The stage 10 includes a base 11 and a support member 12 disposed on the base 11. The support member 12 is hollow inside, forming a first cavity penetrating through the support member 12. A protruding portion and a fixing member 123 cooperating with the first cavity are disposed in the first cavity. The protruding portion protrudes relative to the side wall of the first cavity. The polarizer 40 is placed on the protruding portion and fixed to the protruding portion via the fixing member 123. The outer diameter of the fixing member 123 matches the outer diameter of the first cavity, and the inside of the fixing member 123 is hollow to avoid blocking the polarizer 40 by the fixing member 123. In one embodiment, the fixing member 123 is, for example, an annular retaining ring.

[0022] The first connecting member 20 is used to connect a microscope. The first connecting member 20 is fixedly connected to the first end of the stage 10, specifically to the end of the base 11 away from the support member 12. A first through hole penetrating through the first connecting member 20 is provided inside the first connecting member 20, and an internal thread is provided in the first through hole for connecting the microscope. The second connecting member 30 is used to connect a CCD. The second connecting member 30 is fixedly connected to the second end of the stage 10, specifically to the end of the support member 12 away from the base 11. A second through hole penetrating through the second connecting member 30 is provided inside the second connecting member 30, and an external thread is provided outside the second through hole for connecting the CCD. The first cavity, the first through hole, and the second through hole are coaxially arranged.

[0023] Further, the support member 12 is movably disposed on the base 11. Specifically, a vertical shaft 13 is rotatably disposed inside the base 11. The interior of the vertical shaft 13 has a second cavity that penetrates the vertical shaft 13, and the second cavity is coaxially disposed with the first cavity, the first through hole, and the second through hole. The vertical shaft 13 includes a lower portion and an upper portion. The lower portion of the vertical shaft 13 is rotatably connected to the base 11 via a bearing 14, such that the vertical shaft 13 can rotate relative to the base 11. A fixing groove is provided inside the base 11, and the bearing 14 is disposed inside the fixing groove. The outer ring of the bearing 14 is fixedly connected to the inner wall of the fixing groove via a bearing outer retaining ring 141, the inner ring of the bearing 14 surrounds the lower portion of the vertical shaft 13, and the inner ring of the bearing 14 is fixedly connected to the lower portion of the vertical shaft 13 via a bearing inner retaining ring 142.

The worm 16 is rotatably disposed on the worm gear holder 112 via a bearing, such that the worm 16 can rotate flexibly relative to the worm gear holder 112. The worm 16 meshes with the turbine 15, and the rotation of the worm 16 drives the meshing turbine 15 to rotate, thereby driving the vertical shaft 13 and the support member 12 to rotate. One end of the worm 16 away from the turbine 15 is fixedly connected to the motor output shaft through a coupling, and the input shaft of the motor is connected to a handwheel. Among them, the motor is fixedly disposed on the worm gear holder 112.

[0025] The working principle of the polarizer turntable according to the embodiment of the present application is as follows:

[0026] The microscope is connected to the polarizer turntable via a first connector 20, and the CCD is connected to the polarizer turntable via a second connector 30. Since the first cavity, the first through hole, and the second through hole are coaxially disposed, the microscope connected to the first connector 20, the CCD connected to the second connector 30, and the polarizer 40 disposed in the first cavity are coaxially disposed.

[0027] Further, drive the motor or the handwheel to drive the worm 16 to rotate, thereby driving the turbine 15 meshing with the worm 16 and the vertical shaft 13 and the support member 12 fixedly connected to the turbine 15 to rotate, so as to perform a zeroing operation on the support member 12.
