Magnifying
Objects/ Focusing Image: |
|
|
|
- When viewing a slide through the microscope make sure that the stage is all the way down and the 4X scanning objective
is locked into place.
- Place the slide that you want to view over the aperture and gently move the stage clips over top of the slide to hold it
into place.
- Beginning with the 4X objective, looking through the eyepiece making sure to keep both eyes open (if you
have trouble cover one eye with your hand) slowly move the stage upward using the coarse adjustment knob until the
image becomes clear. This is the only time in the process that you will need to use the
coarse adjustment knob. The microscopes that you will be using are parfocal, meaning that
the image does not need to be radically focused when changing the magnification.
- To magnify the image to the next level rotate the nosepiece to the 10X objective. While looking through
the eyepiece focus the image into view using only the fine adjustment knob, this should only take a
slight turn of the fine adjustment knob to complete this task.
- To magnify the image to the next level rotate the nosepiece
to the 40X objective. While looking through the eyepiece focus the image into view using
only the fine adjustment knob, this should only take a slight
turn of the fine adjustment knob to complete this task.

Total

To figure the total magnification of an image that you are viewing through
the microscope is really quite simple. To get the total magnification take the power of
the objective (4X, 10X, 40x) and multiply by the power of the eyepiece, usually 10X. |
