The coarse-adjustment knob moves the body tube up and down to allow focusing of the image.
The coarse-adjustment knob moves the body tube up and down to allow focusing of the image.
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.
This is the coarse adjustment knob. This should be used before the fine adjustment knob (the smaller knob) - which is for fine focusing.
The course adjustment knob on a compound light microscope is used for making large changes in focus when initially locating a specimen. It is typically used with low-power objectives to quickly bring the specimen into view. Once the specimen is roughly focused, the fine adjustment knob should be used for precise focusing. Using the course knob with high-power objectives can risk damaging the slide or the lens.

Two knobs are used to get a clear image on low power. The coarse adjustment knob is used to make drastic changes to the image, and the fine adjustment knob is used to make small adjustments to the image. The reason two knobs are used is because you are supposed to get as clear an image as possible on low power before moving on to the next power, and same with medium power.

The focusing knob on a microscope is used to adjust the position of the lenses and bring the specimen into sharp focus. By turning the focusing knob, you can move the lenses closer or farther away from the specimen to achieve a clear image.
You use the Fine Adjustment Knob to give a very clear image on the microscope, mostly used on high power magnification.
The fine adjustment knob should be used to focus the image while absorbing a specimen under medium power. The fine adjustment knob allows for precise focusing by making small adjustments to the focus point.
You should first use the coarse focusing knob to bring the specimen into view. Once the object is roughly focused, you can use the fine focusing knob to sharpen the image.
AnswerFine adjustment knobs can be used on any of the different power lenses. Fine adjusting knobs help in clarifying a partially focused image.
When focusing the object under low power, you should use the coarse focus knob first to bring the object into general focus. Once the object is roughly in focus, then you can use the fine focus knob to sharpen the image.
On high power, use the fine focus knob to make small adjustments to sharpen the image. The fine focus knob allows for precise focusing at higher magnifications without causing the stage to move too quickly. Avoid using the coarse focus knob at high power as it may result in overshooting the image and potentially damaging the lens or slide.
