it is the course focus
The large knob on a microscope is typically known as the coarse focus knob. It is used to quickly adjust the distance between the objective lens and the slide, allowing for rapid focusing on the specimen. This knob provides a significant range of movement, making it easier to locate the sample before using the fine focus knob for precise adjustments.
it is the COURSE adjustment knob
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.

fine adjustment knob
The large knob on the side of a microscope is used for coarse focusing, which moves the objective lens closer or farther from the specimen in larger increments. The small knob is for fine focusing, which allows for precise adjustments to bring the specimen into clear focus.
The small knob is called the fine focus knob, and the big knob is called the coarse focus knob on a microscope. The fine focus knob is used for precise focusing, while the coarse focus knob is used for initial focusing.
Focusing, its called a focusing knob.
The fine adjustment knob on a microscope is typically located on one side of the base near the coarse adjustment knob. It is used to make precise focusing adjustments when viewing a specimen under high magnification.
The rough focusing knob on a microscope moves the objective lens or the stage closer to or farther away from the specimen in large increments. This allows you to quickly adjust the focus to get the specimen into view before using the fine focusing knob for precise focusing.
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.
