Steps for placement using a microscope
Q: What are the steps for using the microscope
answer:
1. Take the mirror and place it
1. Hold the mirror arm with your right hand and hold the mirror mount with your left hand.
2. Put the microscope on the test table, slightly to the left (the microscope is placed about 7 cm away from the edge of the test table
place). Install the eyepiece and objective lens.
Second, the light
3. Rotate the converter to align the low magnification objective lens with the clear aperture (the front end of the objective lens should be kept 2 cm away from the stage).
4. Aim a larger aperture at the clear aperture. Look into the eyepiece with the left eye (the right eye is open to facilitate simultaneous drawing later). Rotate the reflector so that the light is reflected into the lens barrel through the clear hole. Through the eyepiece, you can see a bright white field of view.
3. Observation
5. Place the slide specimen to be observed (it can also be made of a thin paper sheet printed with the word "6") on the stage and press it with a clamp, and the specimen should be facing the center of the clear hole.
6. Turn the coarse focusing screw to slowly lower the lens barrel until the objective lens is close to the slide specimen (eyes look at the objective lens,
to avoid the objective lens touching the slide specimen).
7. Look into the eyepiece with the left eye, and turn the coarse focus screw in the opposite direction, so that the lens barrel slowly rises until the object is clearly seen as
end. Then turn the fine focus screw slightly to make the image seen more clearly.
8. Use of high magnification objective: Before using the high magnification objective, you must first find the observed object with the low magnification objective, and adjust it to
The center of the field of view, and then turn the converter to change the high magnification lens. After switching to a high-power lens, the brightness in the field of view becomes darker, so the general
Choose a wider aperture and use the concave side of the mirror, then adjust the fine focus screw. Fewer objects are viewed, but
volume becomes larger.
Fourth, finishing
8. After the experiment, wipe the surface of the microscope clean. Turn the converter to deflect the two objective lenses to the side and move the
The barrel is lowered slowly to the lowest position, and the reflector is placed vertically. Finally, put the microscope in the mirror box and return it to its original place.
