The
My First Lab
®
DUO SCOPE™
has the capability to illuminate the
specimen from the top (stereo microscope) or the bottom (compound
microscope). Notice the power switch located on the back of the scope. This is
a 3 way switch to operate either the bottom light (set to the single line), both
lights (set to the double line), or set to the off position (circle in between the
two lines).
Operation
Viewing Slides
Begin with the stage platform at its lowest position. To observe specimens,
check the objective lens, and if necessary, rotate the nosepiece
so that the 4X
objective lens is in position for viewing. The lens will “click” when in place.
Focusing Tip
Always start viewing any specimen with the 4X objective and
increase accordingly.
Begin by selecting a prepared slide and placing it carefully on the stage
(labeled side up). Push gently on the back of the clips enough to slip the slide
under and hold it in place. The main part of the specimen should be centered
over the opening in the stage.
Turn on the bottom light (single line on power switch) to shine the light up
through the stage and through the specimen on the slide.
Look through the eyepiece and SLOWLY turn the focusing knob until the
Nosepiece
4X Objective
Rotate the nosepiece to the 4X objective for viewing
and your image is magnified 40X.
