Parts of Microscope
| Term | Definition |
|---|---|
| Eyepiece | This is the lens that magnifies the specimen, usually by 10 times. This is the lens you look into. |
| Course Adjustment Knob | This knob moves the stage up or down to focus on the specimen. This is the first knob you use to focus on a specimen. |
| Fine Adjustment Knob | Use this lens to sharpen an image under low and medium power. It is the only adjustment knob needed with the high power lens. |
| Revolving Nosepiece | This is where the objective lenses are mounted. Rotate the lens to select low, medium, or high powered. |
| Objective Lens | There are 3 lenses that magnifie the specimen: low power(4✖️), medium power(10✖️), high power(40✖️). Keep the lens free of dirt and fingerprints. |
| Stage | This is where you place a slide for observation. Always keep the stage drie. |
| Stage Clips | These are used to hold a slide in position on the stage. |
| Diaphragm | This has different sized holes that let different amounts of lit pass through the specimen on the stage. |
| Lamp | The lamp supplies the light that passes through the specimen on the stage. Microscopes that do not have a lamp use a mirror to collect and direct light. |
| Arm | The arm holds the tube in place and is used to carry the microscope |
| Base | This provides a stable platform for the microscope. Always set it on a flat, dry, uncluttered surface. |
| Tube | The tube separates the ocular lens from the objective lens at a distance calculated for proper magnification. |
| Condenser Lens | This lens is under the stage. It helps focus light onto the specimen on top of the stage. |
