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.
Which focusing knob do you never use under high power?
The coarse adjustment knob should never be used when viewing in high power with a compound microscope. When in high power, use the coarse adjustment (the knob smaller than the coarse adj.) to more accurately focus on the subject.
Why should you use the fine focus knob only when working with the 40x objective lens?
The fine focus knob should be used only with the 40x objective lens because this lens has a narrow depth of field which requires precise adjustments to bring the specimen into focus. Using the fine focus knob with other objective lenses may cause damage to the lens or slide due to the rapid movement of the focusing mechanism.
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!!!!

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.
Why should you only use the fine adjustment knob when you are using high power?
The fine adjustment knob should be used with high power magnification because it allows for smaller, more precise movements of the objective lens. This helps to prevent damage to the slide and objective lens, as well as minimize the risk of crashing the objective lens into the slide.
When is the only proper time to use the fine adjustment on a microscope?
The fine adjustment on a microscope should be used when you need to make precise focusing adjustments to clearly observe the details of a specimen. It is typically used after using the coarse adjustment knob to bring the specimen into approximate focus.

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.
