The key points of its technical solution are: it includes a base, a support block is fixedly installed on the bottom surface of the base, a rubber pad is fixedly installed on the bottom surface of the support block, and a light microscope imaging assembly is arranged on the top surface of the base, and the light microscope imaging assembly includes a plane mirror, an imaging plate and a candlestick.

[0004] During the use of the above device, the height of each component of the optical mirror cannot be freely adjusted, and the changes in the height of the candlestick, convex lens and frosted glass cause changes in the light source, which is an important test point of the experiment. The current device cannot be displayed intuitively; therefore, we proposed a combined optical mirror device for physical experiments to solve the above problems. Utility Model Content

[0012] A second slider is arranged on the reverse screw rod and is drivingly connected to the reverse screw rod, and a frosted glass is arranged on the upper end of the second slider;

[0019] 1. During the experiment of the utility model, the teacher can control the operation of the stepper motor of the guide rail to drive the forward screw and the reverse screw, and synchronously control the movement of the first slider and the second slider, so as to equidistantly adjust the spacing between the convex lens, the luminous body and the frosted glass, so as to facilitate the observation of the imaging effects of different spacings. In order to make the experiment more intuitive, the teacher can also lift the convex lens, the luminous body and the frosted glass one by one to achieve the effect of changing the height of each component. Because the convex lens, the luminous body and the frosted glass are all fixed by weak magnetic adsorption, they can be separated with a little force.
