| Eyepiece (Ocular Lens) | the part of a compound light microscope that magnifies an image, usually 10 times |
| Objective Lens | the part of a compound light microscope that is located directly above the specimen and that magnifies the image of the specimen |
| Stage | a platform of a compound light microscope that supports the slide holding the specimen |
| Light Source | a light bulb that provides light for viewing an image on a slide with a microscope |
| Magnification | the increase of an object's apparent size by using lenses or mirrors |
| Nosepiece | the part of a compound microscope that holds the objective lens in place above the specimen |
| Resolution | in microscopes, the ability to form images with fine detail |
| Scanning Electron Microscope | a microscope that produces an enlarged, three dimensional image of an object by using a beam of electrons rather than light |
| Transmission Electron Microscope | a microscope that transmits a beam of electrons through a very thin slice of specimen and that can magnify up to 200,000 times |
| Metric System | a decimal-based standard system of measurement that is used by scientists; similar to the SI |
