2. Mirror arm, the part that holds the mirror; Stage, where slide specimens are placed. There is a light hole in the middle and two flat clips on both sides.
3. The upper end of the lens barrel is equipped with an eyepiece, and the lower end is equipped with a converter; Converter; A rotatable disk with an objective lens.
4, coarse focus screw, when rotating, can greatly improve the lens barrel.
5. Fine quasi-focus spiral, the lifting range of the lens barrel is small when rotating, which can make the object image clearer.
6, eyepiece and objective lens, eyepiece is a lens with eyes to observe; An objective lens is a lens close to an object.
7, shutter, there are round holes of different sizes, called aperture. The light intensity can be adjusted for light holes with different apertures.
8, reflector, one side is a plane mirror (when the light is strong), one side is concave mirror (when the light is weak). Rotating the reflector can make the light reflect upward through the light hole.

Precautions for microscope use:
1. When moving the microscope, hold the mirror arm with one hand, the mirror base with the other hand, and the two upper arms are close to the chest wall. Don't lift it obliquely with one hand and swing it back and forth to prevent the lens or other parts from falling.
2. When observing the specimen, the microscope should keep a certain distance (5cm) from the edge of the experimental platform to avoid the microscope falling to the ground. The inclination angle between the mirror column and the mirror arm shall not exceed 45 degrees, and it shall be restored immediately after use.
3. When using, operate strictly according to the steps, be familiar with the performance of each part of the microscope, and master the relationship between the rotation direction of the coarse and fine buttons and the lifting of the lens barrel. When turning the coarse adjustment button down, you must look at the objective lens.
4. Cover the temporary specimen with liquid, and don't use oblique joints to avoid liquid polluting the lens and microscope.
5. The coarse and fine buttons should be used together. The spinner button should not be excessively rotated in one direction. When adjusting the focal length, observe that the lens barrel descends from the side to avoid crushing the specimen and lens.
