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 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.
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.
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.
You should always use the fine adjustment on a microscope when you are focusing on high-power magnifications, typically 400x and above. The fine adjustment allows for precise focusing, which is crucial for observing details without risking damage to the slide or the lens. It is also recommended to use the fine adjustment after initially focusing with the coarse adjustment to enhance clarity.
Use a coarse adjustment knob (large movement) to get near, then use the fine adjustment knob (small movement) to fine-tune.

The course adjustment knob raises and lowers the stage of the microscope. This knob is mainly used on the scanning and low power knob to simply find the specimen. When trying to focus directly, use the fine adjustment knob.

The adjustment knob that moves the body tube for focusing with the high-power objective lens is called the fine focus adjustment knob. It allows for precise adjustments to bring the specimen into sharp focus at high magnifications.
After you adjust the coarse adjustment knob, the fine adjustment knob makes it sharper or clearer.
To focus on a specimen using a microscope, you will typically use the coarse adjustment knob for initial focusing and the fine adjustment knob for precise focusing. The coarse adjustment knob moves the stage up and down quickly to bring the specimen into view, while the fine adjustment knob allows for small, precise adjustments to achieve a clear image.

The Fine Adjustment
The adjustment knob is a component of a microscope that focuses the image of the object being studied. It is used in conjunction with the coarse adjustment knob.
