The focus knob is turned to adjust the focus and get a clear image of the specimen under the microscope. Turning the focus knob moves the lenses up and down to bring the specimen into sharp focus.

When using a specimen microscope, it is important to bring the specimen into focus by adjusting the focus knob until the specimen appears clear and sharp under the objective lens. You may also need to adjust the light intensity and diaphragm to enhance the contrast and visibility of the specimen. Additionally, ensure that the slide is clean and free of any debris that may obstruct the view.
The small disk found under the stage of a microscope is called the diaphragm. It is used to control the amount of light passing through the specimen, helping to adjust the contrast and brightness of the image being viewed. By adjusting the diaphragm, the user can optimize the visibility of the specimen under different lighting conditions.
To view a specimen under high power on a microscope, first ensure the specimen is properly mounted on a slide and in focus under low magnification. Then, increase the magnification to high power, typically 400x or higher, using the lens adjustment knob without contacting the slide. Finally, fine-tune the focus using the fine focus knob to get a clear view of the specimen at high magnification.
You should adjust the fine focus knob to sharpen the image when viewing the onion cell under high-power objective (HPO) on a microscope. Rotate the knob gently to focus the specimen until the image appears clear.

You can adjust the fine focus knob to bring the onion into sharper focus. If the image is still not clear, you may need to also adjust the condenser or the diaphragm to optimize the lighting.
Observing a specimen under different magnifications on a microscope allows for a more detailed examination of its structure and characteristics. This can help in identifying specific features, understanding complex structures, and gaining a deeper insight into the specimen's composition.

When you see a specimen clearly down a microscope, it is referred to as having a "clear or sharp focus" where the details of the specimen are in clear view. This indicates that the specimen is properly in focus under the microscope, allowing for accurate examination and observation.
The objective used when observing a fresh specimen is typically a low-power objective lens, such as a 4x or 10x lens. This allows for a wider field of view and better visualization of the overall sample without the need for magnification.
The cover over the specimen on a microscope is called a microscope slide cover slip. It protects the specimen from dust and damage and helps to maintain the specimen in place while observing it under the microscope.
