This is the coarse adjustment knob. This should be used before the fine adjustment knob (the smaller knob) - which is for fine focusing.
The course adjustment moves the stage of the microscope further/closer away from the objective lens (it is used for general focusing), and the fine adjustment moves the objective lens very small distances for finer focusing.
It is the first knob you should turn to bring the object into rough focus, before tinkering with the finer tuning knobs.

Coarse adjustment on a microscope is a large focusing knob or wheel that moves the objective lenses up and down to quickly bring the specimen into rough focus. It is used to approximately focus on the specimen before fine-tuning the focus using the fine adjustment knob.
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.

The coarse adjustment knob elevates the microscope's stage up and down quickly. The fine adjustment knob does the same thing but more slowly and accurately. In other words, the fine adjustment knob should require more revolutions to elevate the stage as much as the coarse adj. knob does.
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.
