Steps to make the object image clear with a microscope
1,Taking and placing the mirror
① Hold the arm of the mirror with your right hand and the base of the mirror with your left hand.
②Place the microscope on the laboratory table, slightly to the left. Install the eyepiece and objective lens.
2,Lighting
①Turn the converter so that the low-power objective lens is aligned with the aperture. Note that the front of the objective lens and the stage to maintain a distance of 2 cm.
② A larger aperture aligned with the aperture. Left eye looking into the eyepiece, the right eye open, easy to observe later drawing. Turn the reflector, see the bright field of view.
3, observation
① Put the slide to be observed on the substrate, with the slide clamp pressure, the specimen should be directly to the aperture.
② Turn the coarse focusing screw, so that the barrel slowly down until the objective lens close to the slide. Keep your eyes on the objective lens so that it does not touch the slide specimen.
③Left eye looks into the eyepiece, while turning the coarse focusing helix in the opposite direction, so that the barrel of the mirror slowly rises until the object can be seen clearly. Then slightly turn the fine focusing spiral, so that the object image is more clearly seen.
Therefore, the answer is: (1) take the mirror and placed (2) to the light (3) observation; coarse focusing spiral; fine focusing spiral
