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 Magnification: |
|
|
|
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. |
