There are two adjustment knobs (coarse and fine) on a microscope so you can move the stage at two different speeds. The coarse moves a lot per revolution, while the fine adjustment knob moves the stage at such small increments that it is nearly impossible to notice when looking from the side. The coarse adjustment knob should be used to get the stage closer to the lens only while you are looking at the microscope from the side. The fine adjustment knob can be used when you are looking into the microscope because there is a much lower chance of running the stage into the lens and breaking it.
A microscope with 2 eyepieces is called a binocular microscope. This type of microscope allows for viewing with both eyes simultaneously, providing a more comfortable and natural viewing experience. Binocular microscopes are commonly used in laboratories and educational settings.

Adjustment knobs are used to focus light in a light microscope.
A standard compound light microscope typically has three knobs: the coarse focus knob, the fine focus knob, and the stage knob for moving the specimen horizontally or vertically on the stage. Specialty microscopes may have additional knobs for specific functions.
The focusing knobs are used to regulate the low power objectives on a microscope. These knobs help adjust the distance between the specimen and the objective lens to bring it into focus. By turning the focusing knobs, you can achieve a clear image when using low power objectives.
The stage manipulator knobs on a compound microscope are used to move the slide horizontally and vertically on the stage. This allows for precise positioning and focusing of the specimen being viewed under the objective lens.
Stage manipulator knobs on a microscope are used to move the slide horizontally (x-axis) and vertically (y-axis) to position the specimen for viewing. They allow for precise control and adjustment of the position of the specimen on the stage.
The large knob on the side of a microscope is used for coarse focusing, which moves the objective lens closer or farther from the specimen in larger increments. The small knob is for fine focusing, which allows for precise adjustments to bring the specimen into clear focus.
The focusing knob or knobs are used to adjust the focus of a microscope. This allows for clear visualization of the specimen being observed. Rotation of the knobs moves the objective lenses closer or farther from the specimen, bringing it into sharper focus.
Microscopes typically have knobs for adjusting the focus (coarse and fine adjustment knobs), magnification levels (objective lens turret), and the stage (stage control knobs for moving the specimen). Other common knobs include the condenser adjustment knob for controlling the amount of light passing through the specimen and the mechanical stage knobs for precise movement of the specimen.
You see cells through a basic microscope with fine and course focus knobs.
The main parts of a microscope include the eyepiece, objective lenses, stage, diaphragm, light source, and focusing knobs. The eyepiece is where you look through to observe the specimen, while the objective lenses magnify the specimen. The stage holds the slide with the specimen, and the diaphragm controls the amount of light passing through. The focusing knobs are used to adjust the focus of the image.
The stage on a microscope is typically moved using coarse and fine adjustment knobs located on the mechanical stage assembly. These knobs allow the user to move the stage up and down or side to side to adjust the position of the specimen for viewing.
