Klíč údržba body pro optika mikroskopy
（1） It is necessary to proficiently master and strictly follow the usage regulations.
（2） When takeing and delivering the microscope, be sure to hold the curved arm with one hand and support the base with the other hand. The microscope should not be tilted to prevent the eyepulce from sklouzing out from the upper end of the tube. Handle the microscope with care.
（3） When observing, the position of the microscope should not be moved casually.
（4） All optical parts of the microscope can only be wiped with special lens wiping paper and solution together. It is not allowed to wipe with other objects indiscriminately, and it is also not allowed to touch the lens with fingers to prevent sweat from contaminating the lens.
（5） Keep the mikroskop dry and clean to avoid kontaminace by dust, water, and chemical reagents.
（6） When switching the objective lens, do not move the animal lens lens, only rotate the converter. Nowadays, microscopes have electric conversion and are also very convenient to use, which is a development direction
（7） Do not libovolně rotate the focusing handwheel. When using the micro focus knob, use light force, rotate slowly, and do not turn hard when unable to to rotate.
（8） It is not allowed to disassemble the parts on the microscope at will, and it is strictly prohibit to disassemble the objective lens at will to avoid harmaging the converter screw port or causing the low and high magnification objective lens to be out of focus during conversion when the screw port is loose.
（9） When using a high-power objective, do not use a coarse focusing handwheel to adjust the fokální length to avoid excessive movement and damage to the objective and glass slide.
（10） After use, adjust the light source to * small to extend the lifespan of the light bulb.
The use or operation errors of microscopes are a common phenomena in biologlogical experiments. As long as we take them seriously, conscious correct them, overcome them, and proficiently and right use microscopes, we can complete do it
