objectives
In a microscope, the stage controls the movement of the objectives. The stage can be adjusted vertically to bring the specimen into focus and horizontally to move the specimen under the objectives for viewing.
Usually at the end there is a type of dial that you can turn and it could zoom in and out.

To switch objectives on a microscope, you need to rotate the nosepiece that holds the objectives. Simply grasp the nosepiece and turn it until the desired objective clicks into place. Make sure to refocus the image after changing objectives to ensure a clear view.
You rotate the nosepiece or turret to switch between different objectives on a microscope. This allows you to easily change the magnification level for better viewing of the specimen.
The switch objectives on a microscope refer to the rotating turret that holds different objective lenses. By rotating the turret, you can switch between different objective lenses to achieve various magnifications for observing the specimen. Each objective lens has a different magnification power, typically ranging from low (4x) to high (100x).
Depends on the microscope, I would expect. All of the light microscopes I've ever used you could just turn to different objectives, but be careful not to crack the slide in doing so.
The nosepiece, also known as the turret or revolving nosepiece, is the part of the microscope that rotates to switch between different objectives. It holds the objectives in place and allows the user to easily select the desired magnification.
The round piece that holds the two objectives in a microscope is called the nosepiece. It allows you to easily switch between different magnifications by rotating it.
