Why is it important to only use the fine adjustment knob when using the highest power objective lens?

When using high power, the lens is very close to the sample - and so you risk damaging the slide and/or lens if they touch - therefore you only want to move the platform a little bit at a time.
It is very similar with an oil immersion - you don't want to damage the lens by allowing the sample to touch it.

∙ 8y agoOn almost any microscope, when using the high power, or especially for oil immersion objective, the lens is separated from the slide by the width of a gnat's eyebrow. Even a slight adjustment of the knob can smash the objective through the slide.

Which part of a microscope should be used with the low power objective but not with the high power objective?
Coarse Adjustment
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.
What is used to focus when using the scanner and low objective?
The coarse and fine adjustment knobs can be used with the low power objective.
What is the name of the adjustment knob that moves the body tube for focusing with the high-power objective lens?
I assume you would use the fine adjustment knob for high power objectives.
What must NEVER be used when using the medium or high power objectives?
The coarse adjustment because it moves the objective much farther than the fine adjustment knob, and you could hit the slide with the objective and damage the lens and/or the slide.

What precautions must be taken when using a microscope when it is in high power lens?
Because you are at the highest magnification, only turn the fine adjustment knob when you are using the high-powered objective lens, and not the coarse adjustment. Otherwise you risk getting your sample out of focus, and you will probably only be able to refocusby starting with the lowest power objective lens.
What are the steps used to focus a microscope on high power?
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.
What is the meaning of fine adjustment?
it is the function of HPO or the High Power Objective
6 How does the procedure for using the microscope differ under high power?
For low power you can use the coarse adjustment and fine adjustment for 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.
What is used to focus when using the scanner and low objective?
The coarse and fine adjustment knobs can be used with the low power objective.
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.
