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 10x, 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 holing the specimen. |
Light Source | |
Magnification | The increase of an 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 | 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 Systeme Internationale. |
Base Unit | One of the fundamental units of measurement that describes length, mass, time, and other quantities and from which other units are derived. |
