This allows for small adjustments to the focus.
Usually the large focus is used with smaller powers (not zoomed in as much), to locate the specimen and move it closer (or further away) from the lens. The fine focus knob is used once the specimen is almost in focus, or if you are on high power.

∙ 10y agoBecause small adjustments make a huge difference when looking at very tiny things under high mag....if it's easier, imagine a 50x telescope...you're zoomed in on something far away....each twist of the focus knob virtually moves you (your focus) 2 or 3 feet closer to the object...that's a Huge move....when you're looking at something microscopic, such a huge move is too much, so you need fine focus that only moves you a micrometer ...

∙ 8y agoIn a microscope, the fine adjustment helps you focus and clearify what you're looking at when using the HIGH power objective lens.

∙ 9y agoThe fine adjustment on a microscope is what allows one to have a final focus on the specimen. This will adjust the lens by fine-tuning it.

What two structures on the microscope will you use to focus on your specimen?

What is the function of coarse focus adjustment knob on the microscope?
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.
What is the function of the fine adjustment knob?
Assuming that you were talking about a microscope, then . . . the fine adjustment is really the normal adjustment. It's easy to use to get a great focus because it moves the focusing mechanism very little per turn. On the other hand, the fine adjustment simply won't get you close to initial focus without spending a day or two turning the dern thing. On the other hand, the COARSE focusing knob will get you NEARLY to correct focus in a flash.
When using the high power objective which focus knob do you use?
The fine adjustment knob is used with the power objective on the microscope. Since the objective is already at the highest objective possible for that microscope, using the coarse adjustment knob would focus to much on the object making the details harder to read. Using the fine adjustment knob, you are able to see the fine details within the object or organism you are studying. The higher the power, the finer the knob and the lower the objective, the coarser the knob and objective.
