The object on the viewing stage is close to the lens of a microscope. Racking downward risks the lens touching the object and damaging either the object itself or the lens. Before moving the lens down, make sure you can see the lens and the object from the side of the microscope to void the two touching each other.
Focusing, its called a focusing knob.
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.
Turning the coarse adjustment knob of a microscope downwards brings the objective lens closer to the specimen, allowing for initial focusing at low magnification. This is useful for quickly bringing the specimen into view. Turning the coarse adjustment knob upwards moves the objective lens away from the specimen, enabling a higher focal point for fine-tuning the focus at higher magnifications. It is essential to use the coarse adjustment first to avoid crashing the objective lens into the specimen, which can damage both the lens and the specimen.
The coarse focus knob is used to quickly adjust the distance between the objective lens and the specimen on a microscope to bring it into approximate focus. It is mainly used for initial focusing before using the fine focus knob for precise focusing.
Focusing, its called a focusing knob.
Racking downwards the coarse focusing knob while looking down the microscope can damage the lens or slide due to sudden movement or impact. It can also cause the lens to hit the slide, leading to potential damage to both the lens and the object being observed. Additionally, this action may result in a loss of focus and disrupt your observation.
the coarse adjustment
When turning the coarse adjustment on a microscope upwards or downwards, the distance between the tube and the stage changes. This changes the detail of what you can see of the specimen you are examining.

The coarse focusing mechanism in a microscope is used to quickly adjust the distance between the objective lens and the specimen to roughly bring the specimen into focus. This allows the user to start focusing on the specimen before making fine adjustments with the fine focusing mechanism for a clear and detailed image.
