what does the revolving nosepiece do on a microscope

The revolving nosepiece, also known as the revolving turret, is a circular structure located between the ocular lens and the stage of a microscope. It holds two or more objective lenses and can be rotated to easily change the magnification power. Most microscopes provide a low power lens with about 5x magnification and a high power lens with about 100x magnification. The revolving nosepiece allows the user to locate objects using a low power lens and then examine the objects more closely with the high power one. Without the revolving nosepiece, the microscope would only provide one level of magnification. The nosepiece can hold anywhere from 3 to 5 objectives, depending on the microscope. To change the magnification power, the user grasps the objective along the etched grip section of the objective lens and rotates it either clockwise or counterclockwise depending on which objective they are trying to lock into position. The revolving nosepiece is a time-saving and integral part of the working of a microscope.
