The big knob on a microscope is typically called the coarse focus knob. This knob is used to move the objective lenses closer to or further away from the specimen, allowing for rough adjustment of the focus.
The function of a microscope's coarse adjustment knob is to improve focus on the object under study by adjusting the lens. Unlike the fine adjustment, coarse adjustment moves the lenses quickly.
The adjustment knob is a component of a microscope that focuses the image of the object being studied. It is used in conjunction with the coarse adjustment knob.
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.

After you adjust the coarse adjustment knob, the fine adjustment knob makes it sharper or clearer.
The coarse adjustment knob is used for first focusing the microscope. This knob moves the stage up and down quickly to bring the specimen into rough focus.
The fine adjustment knob on a microscope is typically located on one side of the base near the coarse adjustment knob. It is used to make precise focusing adjustments when viewing a specimen under high magnification.
The course adjustment knob on a microscope is used to quickly focus on the specimen by moving the objective lens up or down. It is typically used for initial rough focusing before using the fine adjustment knob for precise focusing.
