Specifications

.
Make sure
the {ield iris diaphragm on the
vertical illuminator
is
opened
all the way
to
start.
.
We recommend
that
you
initially use an easily
recognizable flat specimen.
Place that specimen
on
the
stage.
.
Select a
lower
power
"scanning"
objective
like the 4X or the
10X to find the area of
interest on the
specimen
quickly.
Be sure the objective
"clicks"
into
place
when
you
turn the objective
nosepiece..
r
By
using
the coarse and fine
focus knobs
shown
above, adjust
your
specimen
into locus with
your
left eye closed
(looking
only
through the right eyetube).
With the specimen
in focus, close the
right
eye
you
just
used and
open the left.
lf
the specimen
is out of
focus for the left eye, adjust
the diopter
on
the
eyetube
until the
focus in
correct.
The microscope
is now
adjusted
for
this
user. Focusing
eyetubes allows us
to
compensate
for users that
wear
corrective
eye
lenses. lf
you
wear
glasses, you
may want to remove the rubber eyeguards.
Note: The aperture iris diaphragm
located on the
vertical illuminator can be
"stopped
down" or closed
somewhat to
give
the
observation
of
your
specimen
more or less contrast or
resolving
power.
Stopping down
the iris diaphragm decreases
resolution and brightness but
increases
image
contrast and deDth
of focus.
