image of the specimen becomes clear. Be careful not to let the slide touch the
lens.
Focusing Tip
While focusing, if the stage stops moving, DO NOT FORCE IT. You
may damage the microscope.
The disc diaphragm, located directly below the stage, has six different
apertures (openings), which allow various amounts of light to pass through.
Rotating this disc allows you to modify the amount of light that is transmitted.
Try experimenting with various settings to get the most effective view.
After observing with the 4X objective (which shows you the image magnified
40X), rotate the nosepiece to the 10X objective lens (leave the slide in place
on the stage). SLOWLY turning the focusing knob will enable you to get a clear
view of your specimen at 100X magnification.
Finally, you can turn the nosepiece to the 40X objective, giving you a 400X
magnification of your slide. When increasing magnification, always remember
that the higher the magnification, the closer the objective must be to the
specimen being observed.
Focusing Tips
The 40X lens will appear to be almost touching the slide. This is
normal. Always move the focusing knobs very slowly to avoid breaking the
slide with the objective. Be careful not to put weight against the stage as this
could push it out of focus. (If this occurs, simply readjust the focusing knobs
slightly until you again have a clear view.)
When changing slides, move the stage to its lowest position by turning the
focusing knob, push the clips to remove and replace slides and begin
observing with the 4X objective again.
