Term | Definition |
Compound Light Microscope | A microscope that uses light to illuminate a specimen that is then magnified by two lenses |
Eyepiece (Ocular Lens) | The part of a compound light microscope that magnifies an image, usually 10 times, also called an ocular lens |
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 the image |
Magnification | The increase of a n object's apparent size by using lenses or mirrors |
Nosepiece | The part of a compound light microscope that holds the objective lenses in place above the specimen |
Resolution | In microscopes, the ability to form images with fine detail |
Scanning Electron Microscope (SEM) | A Microscope that produces an enlarge, three-dimensional image of an object by using a beam of electrons rather than light |
Transmission Electron Microscope (TEM) | 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 |
Base Unit | One of the fundamental units of measurement that describes the length, mass, time, and other quantities and from which other units are derived |
