Stage clips : hold the microscope slide in place Stage : supports the microscope slide Diaphragm : regulates the amount of light that enters the body tube Mirror : sends light upward through the diaphragm, the object, and the lenses Base : supports the microscope Mirror Applications. The mirror reflects the light from the outside source through the bottom of the stage. Illumination: The light source for a microscope. All rights reserved. lens used to locate the specimen on a microscope, smallest microorganisms visible only by using an electron microscope. The objective is generally a specimen contained on a slide. Illuminator/Mirror: The light source that is located at the base of the microscope. It typically lets the light from the illumination source be reflected onto the sample you're observing, but blocks any of this light that is scattered or reflected back towards the eyepiece or camera. If your microscope has a mirror, then you need sunlight or some other light source to point at the mirror to view your slide.The mirror is used to focus light up through the hole in the microscope’s stage, or slide platform.
