what is the nosepiece on a microscope

The nosepiece on a microscope, also known as a revolving nosepiece or turret, is a circular structure where the different objective lenses are screwed in. It holds multiple lenses, allowing the user to turn it to achieve various levels of magnification. This part is located between the ocular lens (the eyepiece) and the stage, and it attaches to the lower portion of the microscope’s arm. By rotating the nosepiece, the user can easily change the power and switch between different objective lenses to achieve the desired magnification level.
