MODEL S71000
To view transparent specimen slides, place slide over the
aperture in the middle of the stage, with the specimen
and cover slip on the slide facing upward. The distance
between the specimen and the bottom of the objective
lens will about 1 inch. Grasping the eyepiece tube, gently
slide it down until the objective lens is fairly close to the
slide surface. Note that there is a small-flanged rivet in
the eyepiece tube that will stop the downward movement
of the eyepiece tube before it reaches the slide surface.
Looking through eyepiece, gently pull up on eyepiece tube
until image comes into sharp focus.
To view solid objects such as rocks, plants, insects,
or opaque specimen such as stamps, fabric, etc.: The
focusing procedure is same as described under above.
The only difference is that you will want adequate ambient
light in order to illuminate your opaque specimen from the
top. If the specimen is small and falls through the aperture
at center of stage, place a small piece of paper under
the stage clips on the stage surface. Center the opaque
specimen on the paper. When viewing solid objects,
maximum specimen height is 30mm. Anything taller than
30mm will not come into focus.
