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.
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 happens when you turn the coarse adjustment knob forward?
If you turn the knob away from you, it will come closer to the slide. If you turn the knob towards you, it will move away from the slide/moves up.
What is accomplished by turning the coarse adjustment upwardsdown wards?
The coarse adjustment (up or down) is used to quickly move closer to or away from the focal point of the specimen. The fine adjustment is then used to fine tune the focus and bring the specimen into clear view.Coarse adjustment means big movements up or down. Fine adjustment means very small movements until the specimen is in focus.
What is the use of the coarse adjustment knob?
The course adjustment moves the stage of the microscope further/closer away from the objective lens (it is used for general focusing), and the fine adjustment moves the objective lens very small distances for finer focusing.
Why coarse adjustment screw being used with low power objective?
The depth of field is so small that a very small vertical travel could shift the focus from the top of the specimen to the bottom. A very fine adjustment must be used, which is why the coarse adjustment screw is implemented.
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 accomplished by turning the coarse adjustment upwards downwards?
When turning the coarse adjustment on a microscope upwards or downwards, the distance between the tube and the stage changes. This changes the detail of what you can see of the specimen you are examining.

What part of the microscope should you used to focus the image when using high power objective lens?
First of all, one should never call it high power, it is morecommonly called the "high objective", yet that is not what this question is asking. To answer the question: You use the fine adjustment knob. This knob should be located near the coarse adjustment knob, on the opposite side of the microscope (at the same height as the coarse adjustment knob), or even as a separate knob protruding from the coarse adjustment knob. The fine adjustment knob is smaller in size. You should never, ever use the coarse adjustment knob under the high objective, you could scratch the microscope slide, cover slip, high objective lens, or in a worst case scenario break the high objective lens.
Which activity might lead to damage of a microscope and specimen?
using the course adjustment to focus the specimen under high power
What objective brings a specimen into focus using a microscope?
coarse sdjustment knob
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.
Why must the distance from slide to objective lens increase rather than decrease when coarse focusing with the scannin and low power objectives?
According to my neurons that the distance from slide to objective lens should be increase rather than decrease when coarse focusing with the scanner and LPO to obtain a clearer and more focus structure of a certain specimen.. U must ensure that the coarse adjustment knob is at it's extent and then turn on the fine adjustment knob clockwise for the easier visibility of the specimen =)) - VALERIC ACID ...sPCUTE ..=)
