Do you mean you can't see clearly how to adjust the jewelry micromirror? Adjustment can be made according to the following steps:

First of all: adjust the position of the object to see if it is placed near the light source, and the general plan in front of the body is left.

Then adjust the aperture: firstly, rotate the objective converter to make the low-power objective aim at the aperture, then rotate the shutter to make the large aperture aim at the aperture, observe through the eyepiece with your left eye, and adjust the reflector at the same time until you see a bright circle.

Finally focusing: rotate the coarse focusing screw forward, so that the lens barrel slowly descends, and when the eyes look at the objective lens, the objective lens slowly approaches the object.
