The light bulb that provides light for viewing the image. It can either be reflected from a mirror or an incandescent light from a small lamp | Light Source |
The increase of an object's apparent size by the using of lenses or mirrors | Magnification |
The revolving structure that holds the set of objective lens, and rotates these lenses into place above the specimen | Nosepiece |
The power to show details clearly in an image | Resolution |
Microscope that passes a beam of electrons over the specimen's surface, providing a three-dimensional image of the specimen's surface | Scanning Electron Microscope |
