Binocular Compound Microscope. |
|---|
Things you should know about your microscope: |
|
Name the parts of the binocular compound microscope. |
|
What are the magnification abilities of the objectives on this scope? |
|
What magnification ability do you have on the ocular lens? |
|
What could you do to adjust the contrast on your scope? |
|
When should you use the course adjustment? |
|
When should you not use the course adjustment? |
|
If you turn the light source on your scope and there is no light, what should you check? |
|
Does your scope have an ocular micrometer? |
|
How do you use an ocular micormeter to make measurements? |
In one of the oculars on your microscope, is an ocular micrometer. The scale on the micrometer was calibrated using a stage micrometer to indicate the length of each ocular unit at a particular microscope magnification. |
 |
|
|---|---|---|
The number of ocular units is multiplied by the calibration to determine the exact length of a cell measured. If this Elodea cell was being viewed at 20X and the ocular calibration was 4 um/ocular unit, how long is this cell? |
 |
|
Stereoscopic Dissecting Microscope |
|---|
 |
Name the parts of the stereomicroscope? |
Where would you adjust the magnification? |
|
How do you focus this scope? |
|
What kind of specimens are best viewed using this scope? |
|
| How would you measure a specimen being viewed on this scope? | |
