The revolving nosepiece, sometimes called a "turret," contains 2 or 3 different objective lenses, each of a higher magnification. This enables the user to examine the object on the slide at different magnifications.
The combination of lenses at the viewing end of an optical instrument is called the eyepiece. The purpose of the eyepiece is to magnify the image formed by the objective lens or mirror, allowing the viewer to see a larger and more detailed image.
Nose piece
Subjective lens and objective lens. Hope it helps :)
objective lens
Allows each objective to be swing into position. ---Co0leTs24
Moves the objective lenses.
It is the part that holds the objective lenses in position and at a correct distance with the eye piece
the nose-piece rotates the objective lenses
The tube connects the eye piece to the objective lens. It holds two or more objective lenses and can be rotated.
the magnifyings system include the eye piece i.e. ocular lens and objective i.e. parfocal lenses

The body tube of a compound optical microscope contains two lens systems, the objective lens composed of one or several lenses that magnify the image of the object being examined, and the ocular lens at the eyepiece end. The magnification of the microscope depends on the focal lengths of the two lens systems.
The objective lens magnifies the specimen, producing a real image that is then magnified by the ocular lens resulting in the final image; The total magnification can be calculated by multiplying the objective lens value by the ocular lens value
It holds the objective lens- the lens closest to the slide. A revolving nosepiece holds several lenses, and permits them to be changed easily- changing the degree of magnification
