Coarse adjustment knob.
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.
There are two adjustment knobs (coarse and fine) on a microscope so you can move the stage at two different speeds. The coarse moves a lot per revolution, while the fine adjustment knob moves the stage at such small increments that it is nearly impossible to notice when looking from the side. The coarse adjustment knob should be used to get the stage closer to the lens only while you are looking at the microscope from the side. The fine adjustment knob can be used when you are looking into the microscope because there is a much lower chance of running the stage into the lens and breaking it.
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.
The light intensity control knob should be set to its lowest setting before turning the microscope off. This prevents the light from suddenly flashing at full intensity when the microscope is turned back on. When turning the microscope on, start with the light intensity set to low and gradually increase it to achieve the desired level for viewing.

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 larger knob used for focusing on a microscope is called the coarse focus knob. It is used to make rapid adjustments to bring the specimen into view.
The knob that moves the slide on the stage left and right is called the mechanical stage control knob or the x-axis translation knob. By turning this knob, you can adjust the position of the slide while viewing it under the microscope.
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.
The wheel on a microscope used to make things clearer is called the fine focus knob or fine adjustment knob. This knob allows for precise adjustments to the focus of the specimen being viewed under the microscope. By turning the fine focus knob, the user can bring the specimen into sharp focus for detailed observation.

The knob that moves the stage slightly to sharpen the image on a microscope is called the fine focus knob. It allows for precise adjustments to the focus of the specimen by moving the stage up and down in very small increments.
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 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 stage of the microscope, where the specimen is placed, does not move when the adjustment knob is turned. Instead, the focus of the microscope is adjusted by moving the stage up and down by use of the adjustment knob.
