[0049] like Figure 4 The zoom intensifier shown includes a housing, a turntable 3, and an operating component 4. The following is a detailed description of each component.

[0050] The housing has an installation space 10 inside, and corresponding lens holes 11 and 20 are opened on both ends of the housing. As shown in the figure, the housing is cylindrical, and lens holes 11 and 20 are opened on both ends of the cylindrical housing. Lens holes 11 and 20 are a pair of round holes, corresponding to binoculars.

[0051] In this embodiment: the outer shell includes a base 1 and a top cover 2. The base 1 has an installation space 10 inside. The top cover 2 covers the base 1 and covers the installation space 10. One end of the base 1 and the top cover 2 are respectively provided with mirror holes 11 and 20.

[0052] The zoom intensifier is used to connect the microscope and the eyepiece. To facilitate connection, one end face of the base 1 in the housing is provided with a first connecting part 12 for connecting with the microscope, and one end face of the top cover 2 in the housing is provided with a second connecting part 21 for connecting with the eyepiece, so that the zoom intensifier can be modularly connected and disconnected from the microscope and the eyepiece. In this embodiment: the first connecting part 12 protrudes from one end face of the base 1, and one end face of the top cover 2 is recessed inward to form the second connecting part 21, that is, the first connecting part 12 and the second connecting part 21 adopt a male and female connecting part to avoid reverse installation; the lens hole 11 on the base 1 is opened on the first connecting part 12, and the lens hole 20 on the top cover 2 is opened on the second connecting part 20.

[0053] The rotating disc 3 is rotatably arranged in the mounting space 10 of the base 1. In the embodiment, the housing and the rotating disc 3 are coaxially arranged, and the rotating shaft 33 of the rotating disc 3 is located at the center of the rotating disc 3.
