Compounds Light Microscope |
A microscope that uses light to illuminate a specimen that's magnified by two lenses |
|
|
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 in that magnifies the image of the specimen |
|
|
Stage |
A platform of a compound light microscope that supports the slide holding the specimen |
|
|
Light Source |
Provides light for viewing the image |
|
|
Magnification |
The increase of an object's apparent size by using lens or mirrors |
|
|
Nose piece |
Holds the objectives and can be turn to change from one objective to another |
|
|
Resolution |
In microscopes, the ability to form images with fine detail |
|
|
Scanning Electronic 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 × |
|
|
Coarse Adjustment Knob |
Moves the stage up and down in large increments to allow gross positioning and focusing of the objective lens |
|
|
Fine Adjustment Knob |
Moves the stage slightly to bring the image into sharp focus |
|
|
Total Magnification |
The standard ocular lens magnifies a specimen 10 times to compute the power of magnification of a microscope, the power of magnification of the strongest objective lens in this case 100 times ocular X objective lens |
|
|
Field of View |
The illuminated circle observed when you look through a microscope |
|
|
Diaphragm |
located under the stage controls the amount of light that is allowed to pass through the objective being viewed |
