| A | B |
|---|
| eyepiece/ocular lens | holds the magnifying lens through which we observe the specimen; magnifies specimen 10 times (10x) |
| body tube | holds the objectives at set distances from the eyepiece/ocular lens |
| revolving nosepiece | holds the objective lenses; turns to change lenses |
| high-power objective | magnifies the object 40x |
| low-power objective | magnifies the object 4x |
| stage clips | hold the slide in place |
| stage | supports the slide; light shines through the hole |
| diaphragm | regulates the amount of light that passes through the hole |
| light source | shines through the hole; may be a mirror or electric |
| base | supports the weight of the microscope |
| course adjustment | moves the body tube up and down; is used in low-power focusing |
| fine adjustment | sharpens the image under high-power |
| arm | supports the body tube and the adjustments |
| compound light microscope | three main parts: tube with two lenses, stage, and a light (WE USE THIS ONE!) |
| transmission electron microscope | electrons pass through the specimen; produces a flat image |
| scanning electron microscope | electrons bounce off the specimen; produces a three-deminsional image |
