Want this question answered?
On a light microscope there is the coarse adjustment knob and the fine adjustment knob
The coarse adjustment knobs are used to to lower them dramatic amounts. And the fine adjustment knobs are used to lower them very small amounts, in order to focus in better on what you want.
the big knob is called the coarse adjustment knob and the smaller one is the fine adjustment knob coarse does a large scale focus, fine does such small scale focus you can only see a difference in how the (item under microscope) looks. You don't see the stage / nosepeice move up or down.
the fine adjustrment knobs?
First focus the microscope on the lowest objective using first the coarse djustment knob and then the fine adjustment knob. Once you have it in focus, move on and do the same for the next highest objective. Continue this process until you reach the highest objective and focus it in the same fashion.
The fine adjustment on a microscope is the smaller of the two knobs on the side. It is used after the coarse adjustment, which moves the platform up/down. It is mainly used to focus.
The knobs on the side of a microscope are the focus knobs. The large one is the course focus, and the smaller one is the fine focus.
a good way that works for me is use the coarse adjustment till you can start to see something then use the fine adjustment to get it into focus.
you turn the fine and coarse adjustment knobs

the stage and the objective lens
The coarse focus on a microscope is provided to move the instrument quickly to where it is nearly in focus. Some microscopes only have a coarse focus. The fine focus is used to move with slower and more precise adjustment to where the instrument is exactly in focus.
First use the coarse focus followed by the fine focus.
