Steps for using a microscope Placement
Picking up and placing the mirror
1. Hold the arm of the microscope with your right hand and the base of the microscope with your left hand.
2. Place the microscope on the lab bench, slightly to the left (the microscope is placed about 7 cm from the edge of the bench).
(the microscope is placed about 7cm from the side of the lab bench). Install the eyepieces and objective lenses.
Aligning the light
3. Turn the converter so that the low-power objective lens is aligned with the aperture (the front of the objective lens should be kept at a distance of 2 cm from the stage).
4. Aim a larger aperture at the aperture. Gaze into the eyepiece with your left eye (keep your right eye open for later simultaneous drawing). Turn the reflector so that the light is reflected through the aperture into the barrel of the mirror. Through the eyepiece, a white bright field of view can be seen.
Observation
5. Put the slide specimen to be observed (can also be made of thin paper with "6" printed on it) on the carrier table, press it down with a pressure clamp, and the specimen should be right in the centre of the aperture for light transmission.
6. Turn the coarse focusing screw, so that the barrel of the mirror slowly down until the objective lens close to the slide specimen until (eyes looking at the objective lens, so as not to touch the slide specimen).
so that the objective lens does not touch the slide specimen).
7. Look into the eyepiece with your left eye and turn the coarse focusing screw in the opposite direction so that the barrel of the mirror rises slowly until you can see the object image clearly.
The left eye looks into the eyepiece and turns the coarse focusing screw in the opposite direction. Then turn the fine focusing spiral slightly to make the image clearer.
8. The use of high-magnification objective: before using the high-magnification objective, you must first use the low-magnification objective to find the object of observation, and adjust to the centre of the field of view, and then turn the lens.
The centre of the field of view, and then turn the converter and then change the high power lens. After changing to high magnification, the brightness in the field of view becomes darker, so generally A larger aperture is chosen and the concave side of the reflector is used, then the fine focusing screw is adjusted. The number of objects viewed becomes smaller, but the the number of objects viewed becomes smaller but the size becomes larger.
Organisation
8. When the experiment is finished, wipe the exterior of the microscope clean. Turn the converter, deflect the two objective lenses to the sides, and lower the mirror
The tube is slowly lowered to its lowest point and the reflector is placed vertically. Finally, put the microscope into the mirror box and return it to its original place.
Precautions:
Do not pick up the microscope with one hand.
If you need to move the microscope, be sure to lift the microscope and then put it to the proper position, and do not push the microscope.
Do not push the microscope (the vibration caused by pushing the microscope may lead to the loosening of the internal parts of the microscope, remember!) Please be careful when using the microscope.
The height of the chair should be appropriate when using the microscope, and you should get used to observing with both eyes at the same time, and the aperture and the brightness of the light source should be appropriate.
The aperture and the brightness of the light source should be appropriate, otherwise it is very easy to feel fatigue when observing for a long time.
4. When rotating the rotating disc, make sure to lower the carrier table to the lowest point to avoid scratching the lens of the eyepiece due to improper operation.
5, specimen staining or any other operations should be removed from the slide, and then put back to the carrier table after the operation is completed, do not operate on the carrier table to avoid staining.
Do not operate on the carrier stage to avoid the dye or other liquids flowing into the microscope or hurting the lens.
After observing one kind of material, when you want to change another kind of material, make sure to lower the stage to the lowest point, and then refocus according to the standard procedure after changing the slide.
Then refocus the microscope according to the standard procedure, do not pump the specimen directly to avoid scratching the lens or the slide specimen.
7,After using the microscope, the stage should be lowered to the lowest point and the low magnification lens should be aligned with the round hole in the centre of the stage, the power cord should be rolled up, the dust cover should be covered and the microscope should be put into the storage cabinet.
