Tips and precautions for routine microscope use
With the development of modern science and technology, the types of microscopes are also increasing gradually. Microscopes can be divided into a polarizing microscope, optical microscopes, electron microscopes,s, and digital microscopes according to the microscopic principle. Each microscope has its own unique function, structure, and purpose. But there’s always something in common. What are some tips and precautions for routine microscope use?
Tips for using conventional microscopes
1. Extraction and placement: During extraction, hold the mirror arm with one hand and hold the mirror seat with the other. Placement position: mirror arm close to the body slightly left; The lens base shall be about 5 cm from the edge of the test stand.
2. Slide placement: Put the slide specimen into the gap at the back of the slide holder, push the slide forward slowly with both hands and gently, so that the specimen is directly facing the light hole.
3. Adjust the light: choose the maximum aperture to align with the light hole: focus on the eyepiece with your left eye, turn the reflector with both hands until you see a bright field of vision, and adjust the intensity of the light with a visor.
4. Rotary converter: slowly rotate the converter to align the low-power objective lens with the through-light hole.
5. Focusing observation: Gaze at the objective lens with both eyes, and rotate the coarse quasi-focal screw to make the lens tube descend slowly until the objective lens approaches the glass slide.
Look at the eyepiece with your left eye and rotate the thick centering screw to make the lens tube rise slowly until you see the object image. Then fine-tune the fine centering screw to make the object image clear.
Precautions for using a conventional microscope
(1) If the microscopic lens is found to have stains, it should be wiped gently with special cleaning paper;
(2) the light intensity should use a plane reflector, and weak light should use a concave reflector;
(3) When using the microscope, the action should be light and steady, and the force should not be too fierce.
(4) Observe with your eyes open, not only the left eye (or the right eye);
(5) The reflector should not be facing strong direct light;
(6) Put an end to the hard rolling clamp, and the loading platform should be kept clean and tidy;
(7) Strictly prevent the lens from touching the glass, so as not to crush the glass and scratch the lens, so that the lens can not observe objects better.
