1. If you want to move the object in the upper middle of the field of view to the exact center of the field of view, you should continue to move the mounting film upward. If you want to move the object on the left of the field of view to the very center of the field of view, you should continue to move the mount to the left because the microscope field of view is the inverse image.
2. After changing the high-power objective lens, the fine-focus spiral should be adjusted to make the image clear. The field of view will dim; you can turn up the light or use the cancave mirror of the reflector to lighten the field of view.
3. The longer the eyepiece, the smaller the magnification; the longer the objective lens, the greater the magnification.
4. The smaller the distance between the objective lens and the slide, the greater the magnification.
5. The larger the magnification, the larger and fewer the cells in the field of view, and the darker the field of view.
6. Replace the eyepiece. If the foreign body disappears, the foreign body remains on the eyepiece. Replace the objective lens; if the foreign object disappears, the foreign object is on the objective lens. Move the slide; if the foreign object moves, the foreign object is on the slide.
How do I distinguish between muclei and vacuoles in the microscope field of view? In general, the nucleus is not transparent; it is dark, and the vacuole is light. In addition, careful observation shows that the liquid in the vacuole is flowing and the structure is intact.
