[0022] The term "embodiment" used herein, as an example, is not necessarily to be construed as superior to or better than other embodiments. Performance testing in the embodiments of this application, unless otherwise specified, employs conventional testing methods in the art. It should be understood that the terminology used in this application is merely for describing particular implementations and is not intended to limit the scope of this disclosure.

[0023] Unless otherwise stated, the technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; other experimental methods and technical means not specifically mentioned herein refer to experimental methods and technical means commonly used by one of ordinary skill in the art.

[0024] The terms “basic” and “approximately” as used herein are used to describe small fluctuations. For example, they can mean less than or equal to ±5%, such as less than or equal to ±2%, such as less than or equal to ±1%, such as less than or equal to ±0.5%, such as less than or equal to ±0.2%, such as less than or equal to ±0.1%, such as less than or equal to ±0.05%. Numerical data presented or expressed in range format herein are used for convenience and brevity only, and should therefore be interpreted flexibly to include not only the explicitly listed values ​​that define the range, but also all independent values ​​or subranges contained within that range. For example, a numerical range of “1–5%” should be interpreted to include not only the explicitly listed values ​​from 1% to 5%, but also the independent values ​​and subranges within the indicated range. Thus, this numerical range includes independent values ​​such as 2%, 3.5%, and 4%, and subranges such as 1%–3%, 2%–4%, and 3%–5%, etc. This principle also applies to ranges that list only one value. Furthermore, this interpretation applies regardless of the width of the range or the characteristics described.

[0029] Please see Figures 1 to 4This utility model provides an embodiment of a miniaturized two-position rotary table, comprising a mounting housing (1), a stepper motor (2), and a filter turntable assembly (3). The mounting housing includes an aviation connector (11) and a control board (12), and the filter turntable assembly (3) includes a two-position filter turntable (32) and a counterweight (31). The mounting housing (1) is a cuboid shell structure with an aviation connector (11) hole on one side and a detachable cover (13) on the other side perpendicular to the aviation connector (11). The detachable cover (13) has a through hole for the motor shaft. The stepper motor (2) is installed inside the mounting housing (1) and fixed by the detachable cover (13). The filter turntable assembly (3) is rigidly connected to the motor shaft of the stepper motor (2). The two-position filter turntable (32) is fan-shaped, and the counterweight (31) is installed at the tail end of the two-position filter turntable (32). The length, width, and height of the mounting housing (1) range from 50mm to 60mm, 40mm to 50mm, and 50mm to 60mm, respectively. The detachable cover (13) is also equipped with an adjustable positioning post (14), the angle of which is adjustable from 0° to 60°. The filter turntable (32) is made of aluminum alloy, POM polyoxymethylene plastic, or PEEK polyetheretherketone plastic. The filter turntable (32) also has a filter mounting through hole (33), the diameter of which is Ø10mm-Ø30mm. The filter is fixed on the filter turntable (32) by a pressure ring. The mass ratio of the counterweight (31) to the filter turntable (32) is between 0.9 and 1.1. The ratio of the lever arm of the center of mass of the counterweight (31) to the center of mass of the filter turntable (32) from the axis of the stepper motor (2) is between 1 and 1.2. One side of the counterweight (31) has a bolt post structure, and the tail end of the two-position filter turntable (32) has a threaded hole structure. The connection between the counterweight (31) and the tail end of the two-position filter turntable (32) is a threaded connection. The threaded connection between the counterweight (31) and the tail end of the two-position filter turntable (32) is an M1 threaded connection.

[0030] In use, the device is first mounted on the corresponding microscope via the mounting housing (1). The control board (12) is connected to the host computer via the aviation connector (11). Two color filters with a diameter of Ø15mm are mounted on the filter mounting holes (33) on the filter turntable (32). Then, the device is powered on. The control board (12) sends a control command `rug 0` to the stepper motor (2) via the FPGA module to reset it. Figure 3As shown, when a switching operation is required, the host computer sends a control command to the control board (12). The control board (12) sends a control command `rug 1` to the stepper motor (2) via the FPGA module. The stepper motor (2) then rotates its motor shaft by approximately 55° and transmits the power to the two-position filter turntable (32). The two-position filter turntable (32) rotates approximately 55° to the first workstation within about 90ms. Figure 4 As shown, when switching is required again, the control board (12) sends a control command `rug 2` to the stepper motor (2) via the FPGA module. The motor shaft of the stepper motor (2) rotates approximately 55° and transmits the power to the two-position filter turntable (32). The two-position filter turntable (32) rotates 55° to the second position in about 90ms. During the rotation, the angular velocity of the two-position filter turntable (32) is approximately 10.67 rad / s, which will cause strong mechanical disturbances when stopped suddenly. The counterweight (31) and the two-position filter turntable (32) form a lever structure, which acts as a resistance to the rotational torque provided by the stepper motor (2), effectively buffering the mechanical disturbances caused by sudden stops. This utility model achieves rapid switching and ensures high precision and repeatability through the setting of the counterweight. It also features a miniaturized and modular design, making it easy to integrate into various optical systems.
