What does the fine adjustment knob on a microscope do?
The fine adjustment, the two little knobs on both sides of a compound microscope, is rotated to move the body tube down or the stage up in tiny distances to help you focus in HIGH power.The fine focus knob is geared with a different ratio than the coarse knob to "fine tune" your focus. It allows for tiny adjustments to the focus setting, rather than larger ones.
The fine adjustment knob is used to focus an image only on what power?
AnswerFine adjustment knobs can be used on any of the different power lenses. Fine adjusting knobs help in clarifying a partially focused image.
Why should you use the fine focus knob only when working with the 40x objective lens?
You should have already used the Coarse adjustment on 10x so when you switch to 40x, all you need to do is fine adjust it. Plus, you don't want to break it by turning the Coarse up all the way.
When using a microscope what should the slide be placed on for viewing?
Ideally, the microscope should be returned to its lowest-magnification objective when the user finishes his or her work. Because not all users abide by this unwritten law, it's best-practice to use the "Fine Focus" knob (the smaller diameter of the two, usually farthest from the body of the scope) when first sitting at a microscope you don't own. This will prevent the sample from breaking because you've accidentally moved the stage (the moveable, horizontal part of the microscope on which your specimen sits) too rapidly after the last use took off, leaving the objective at 40x (400x total magnification in most instances). If you verify that the objective turret is set such that the lowest magnification objective is in place, you can usually safely use the larger knob located closer to the body of the 'scope (but on the same axis as the fine knob) to bring your sample into focus. As you move to higher powers, the fine is all the adjustment you should need. COARSE, you didn't even end up answering the question previous writter! seriously!!!!! i agree with you 2nd writer!!!!
Why use the fine adjustment to focus a microscope?
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.

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.
Should the course adjustment knob be used for focusing with all three objectives?
Yes, but only to do the most basic focusing. Keep in mind that you can break your slide if you move too close with the coarse adjustment knob and any focusing close to the slide should be done with the fine adjustment knobs. (taught HS Chemistry). Hope that helps!
What are the adjustment knobs on the microscope used to change focus?
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.

Why cant the coarse adjustment knob be used on high power lenses?
The coarse adjustment knob is used for making major changes to the focus, and is therefore too inaccurate to use at high powers, where only a very fine adjustment can drastically change the clarity of the picture you see.
How does the procedure for using the microscope different under high power as oppose to low power?
use the fine adjustment knob to get a better view of what you are looking at.For low power you can use the coarse adjustment and fine adjustmentfor high power you should only use the fine adjustment because on high power, the objective lens is too close to the slide and using the coarse adjustment may scratch the objective lens.
