What are the 2 knobs on a microscope called?
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.

it is used for final focusing.
What is the function of the coarse adjustment knob?

What is the function of the fine and coarse adjustments?
With the "coarse" adjustment, the adjustment mechanism causes a large amount of movement in the thing being adjusted with very little movement of the adjusting mechanism. With the "fine" adjustment, the adjustment mechanism causes a small amount of movement in the thing being adjusted with a lot of movement of the adjusting mechanism. Frequently the two adjustments will be two knobs each with different gearing - say on a telescope focus mechanism. The coarse adjustment allows the telescope focus to be moved quickly then the fine adjustment allows the observer to gently bring the focus to be "pin sharp".

The fine adjustment allows for precise focusing, which is crucial for observing details without risking damage to the slide or the lens. It is also recommended to use the fine adjustment after initially focusing with the coarse adjustment to enhance clarity.
