The coarse adjustment knob should be used first to bring the specimen into general focus. Then, the fine adjustment knob can be used for precise focusing.
Always carry the microscope with two hands, one on the base and one on the arm, to prevent dropping or damage. When focusing, use the coarse adjustment knob first for large adjustments, and then the fine adjustment knob for more precise focusing.
The coarse adjustment knob is typically the first knob to be used when focusing a microscope, as it moves the objective lenses closer to or farther away from the specimen to bring it into view.
The coarse adjustment knob brings objects into rapid focus by quickly moving the stage up or down. It is used first to focus roughly on the specimen before fine-tuning with the fine adjustment knob.
You should first use the lowest power setting of a microscope to find an object and then center it within the viewing area. Then, when you switch to the next higher magnification, your target should still be close to the center and easier to find and focus on.

This is the coarse adjustment knob. This should be used before the fine adjustment knob (the smaller knob) - which is for fine focusing.

The coarse adjustment knob is used for first focusing the microscope. This knob moves the stage up and down quickly to bring the specimen into rough focus.
The coarse adjustment knob is used for first focusing when using a microscope. It is used to move the objective lens closer to or farther away from the specimen to bring it into rough focus.
It is the first knob you should turn to bring the object into rough focus, before tinkering with the finer tuning knobs.

First, make sure that the specimen and the lens are clean. Check the focus adjustment on the microscope to ensure it is correctly set. If the image is still blurry, try adjusting the lighting or the contrast settings to improve clarity.
