| Term | Definition |
|---|---|
| OCCULAR (EYEPIECE) | Where you look through to see the image of your specimen |
| BODY TUBE | The long tube that holds the eyepiece and connects it to the objectives. |
| NOSEPIECE | The rotating part of the microscope at the bottom of the body tube; it holds the objectives |
| OBJECTIVE LENSE | (low, medium, high, oil immersion) the microscope may have 2, 3 or more objectives attached to the nosepiece; they vary in length (the shortest is the lowest power or magnification; the longest is the highest power or magnification) |
| ARM | Part of the microscope that you may carry the microscope with |
| COARSE ADJUSTMENT KNOB | Large, round knob on the side of the microscope used for focusing the specimen; it may move either the stage or the upper part of the microscope |
| FINE ADJUSTMENT KNOB | Small, round knob on the side of the microscope used to fine tune the focus on your specimen after using the coarse adjustment knob. |
| STAGE | Large, flat area under the objectives; it has a hole in it that allows light through; the specimen/slide is placed on the stage for viewing |
| STAGE CLIPS | Shiny, clips on top of the stage which hold the slide in place |
| DIAPHRAGM | Controls the amount of light going through the aperature |
| MIRROR (LIGHT) | Source of light usually found near the base of the microscope; the light source makes the specimen easier to see. |
| LENSE PAPER | Lenses should be cleaned with |
| LOW POWER | Microscope should be stored this way and a specimen should always be brought into focus with this. |
| MEASURES LENGTH | Meter (m), kilometer (km), centimeter (cm), millimeter (mm), micrometer (also micron - pm) |
| MEASURES MASS | Gram (g), kilogram (kg), milligram (mg) |
| MEASURES VOLUME | Liter (L), milliliter (mL), cubic centimeter (cm3 or cc) |
