The performance of a microscope is affected by several factors
1. When holding the mirror, you must hold the arm with your right hand and hold the seat with your left hand. Do not pick it up with one hand to avoid parts falling off or colliding with other places.
2. Handle with care, do not place the digital metallographic microscope on the edge of the laboratory table, so as not to knock it over and fall to the ground.
3. Keep the metallographic microscope clean. The optical and lighting parts can only be wiped with lens cleaning paper. Do not wipe with your mouth or hands or with a cloth. Wipe the mechanical part with a cloth.
4. Do not allow water droplets, alcohol or other drugs to touch the lens and mirror stand. If it is stained, wipe it off immediately.
5. When placing the slide specimen, it must be aligned with the center of the light hole, and the slide cannot be reversed to prevent the slide from being crushed or the objective lens damaged.
6. Develop the habit of opening both eyes at the same time, observe the field of vision with the left eye, and use the right eye for drawing.
7. Do not remove the eyepiece arbitrarily to prevent dust from falling into the objective lens, and do not disassemble various parts arbitrarily to prevent damage.
8. After the metallographic microscope is used, it must be restored before it can be put back into the mirror box. The steps are: remove the specimen sheet, turn the rotator to make the lens leave the light hole, lower the stage, place the mirror flat, and lower the light collector ( But do not touch the reflector), close the aperture, return the film pusher, cover with silk cloth and outer cover, and put it back into the laboratory cabinet. *Finally fill out the registration form. (Note: The reflector should usually be placed vertically, but sometimes because the light collector is not lifted to the proper height, the aperture will be damaged when the mirror stage descends, so it is changed to be placed horizontally here)
