What are the frequently asked questions about using optical microscopes?
1. The problem of light in optical microscopes. Regarding light is an important step when using an optical microscope. Remember to use a low magnification mirror to examine the light. When the light source is strong, use a small focal length or flat mirror, while when the light source is poor, use a large aperture lens or concave mirror. When rotating the rearview mirror, do not pull it out with one hand. Use both hands to rotate it until you see a uniform and bright circular line of sight. After aligning the light, do not move the optical microscope randomly to prevent the light source from accurately entering the Confucius through the rearview mirror.
2. The difficulty of objective lens transformation. After using a low magnification lens, people usually prefer to immediately rotate the objective lens with their fingers, thinking that it is more effortless. However, it is very easy to tilt the optical axis of the objective lens because the raw material of the converter is too soft in color and has high precision. The uneven external thread support is very easy to loosen. Once the external thread is damaged, all converters will be charged. Therefore, the editor suggested that everyone hold the next rotating plate of the converter and change the objective lens.
3. The difficulty of using high-power microscopes with eyes. When using high-power microscope blocks, everyone should keep their eyes apart and stare into the eyepiece with their right eye as close as possible. They should try to stare into the line of sight without forcefully covering or closing their right eye, as it does not comply with the observation regulations of the experiment. Often, the right eye is prone to fatigue, and it cannot be guaranteed to draw while observing.
