standard
eyepieces
and
attachment
lenses
it
is
possible
to
obtain
any
magnification
from
2.5X
to
280X.
NOTE:
Due
to
the

r
Wide
Field
Eyepieces
provide
a
margin
of
eye
relief
that
assures
comfortable,
efficient
viewing
with
the
sharpest
possible
focus
from
center
to
edge.
They
can
be
supplied
in
lOX,
15X
or
20X.
The
lOX
Eyepieces
have
long
eye-relief,
but
for
those
who
must
wear
glasses.
To
eliminate
bothersome
stray
light,
Eyeguards
are
regularly
supplied
for
use
with
these
eyepieces.
For
those
who
do
not
wear
glasses
these
Eyeguards
serve
to
quickly
position
the
eyes
at
the
correct
distance
from
the
Eyepieces.
The
Eyepiece
Adapters
on
the

VIEWING
PROCEDURE
Focusing
1.
Set
the
Magnification
BCnob
to
IX
(low
power).
Center
the
specimen
within
the
field
of
view
and
adjust
the
Focusing
Knob
until
the
best
image
is
obtained.
2.
Set
the
Magnification
Knob
to
7X
(high
power)
and,
using
only
your
right
eye,
adjust
the
Focusing
ICnob
until
the
image
is
critically
sharp.
The
right
Eyepiece
is
now
properly
focused.
NOTE:
Depth
of
field
decreases
as
magni
fication
increases.
It
is
about
20
times
as
great
at
IX
as
it
is
at
7X.
Hiis
means
that
while
it
is
quicker
and
easier
to
bring
the
specimen
into
focus
at
low
power,
the
most
critical
focus
can
only
be
achieved
at
high
power.
3.
Reset
the
Magnification
Knob
to
IX
(low
power)
and,
using
only
the
left
eye,
turn
the
Eyepiece
Adjusting
Ring
until
the
image
is
clear
and
sharp.
Make
sure
the
Eyepiece
maintains
contact
with
the
Ad
justing
Ring.
The
left
Eyepiece
is
now
properly
focused.
The
microscope
will
now
be
properly
focused
for
both
your
eyes
throughout
the
magnification
range.
A
change
in
speci
men
may
require
a
slight
readjustment
of
the
Focusing
Knob.
NOTE:
Operators
who
normally
wear
glasses
with
a
correction
of
2
or
more
Diopters,
and
don't
wear
them
when
usingthemicro
scope—may
find

when
changing
magnification.
Changing
Magnification
To
change
magnification,
simply
set
the
Magnification
Knob
to
any
value
between
IX
and
7X:
Total
magnification
=
Variable
Power
X
Eyepiece
Power
x

if
any.
There
is
no
"image

when
chang
ing
from
one
magnification
to
another.
The
power
range
can
be
further
extended
by
changing
Eyepieces
or
by
adding
Attachment

MEASURING
PROCEDURE
The
StereoZoom
7
may
be
used
as
a
measur
ing
instrument
by
inserting
a
reticle
in
one
of
the
Wide
Field
Eyepieces.
Avariety
of
linear
and
grid
patterned
reticles
are
available.
For
all
measurements
it
is
advisable
to
use
the
lowest
possible
magnification.
The
unit
of
measure
will
often
control
the
magni
fication
you
may
use.
Select
the
magnifica
tion
that
will
enable
you
to
see
the
necessary
detail
and
yet
cover
as
much
total
area
of
the
specimen
as
is
required
and
be
compatible
with
the
unit
of
measure.
Selecting
a
Reticle
Disc
First
decide
what
unit
you
want
to
measure
the
specimen
by,
then
use
the
following
formula
to
determine
what
reticle
will
provide
the
unit.
K
=
SM
K
=
actual
dimension
of
each
smallest
divi
sion
of
the
reticle.
S
=
value
you
want
each
smallest
division
to
represent
on
the
plane
of
the
specimen.
M
=
Magnification
of
objective
system
which
is
the
setting
on
the
Magnification
Knob
X
magnification
of
Attachment
Lens
if
one
is
used.
(Note
that
this
is
not
total
magnification.)
Both
K
and
S
must
be
the
same
unit
of
measurement.
EXAMPLE:
Desired
dimension
of
division
on
specimen
=
.002"
Magnification
Knob
Setting
=
2X
Actual
dimension
of
division
on
reticle
=
.004"
(approximately
0.1mm).
Inserting
the
Reticle
Disc
1.
Unscrew
the
black
cylindrical
field
dia
phragm,
Fig.
12,
from
the
right
Eyepiece.
2.
Place
the
reticle
on
top
of
the
field
diaphragm
so
that
the
scale
will
face
downward
when
the
Eyepiece
is
in
the
microscope.
3.
There
is
a
thin
metal
lip
which
extends
beyond
the
surface
of
the
glass.
Using
a
pencil,
thumbnail,
or
similar
object,
press
against
the
outside
of
the
lip
to
force
it
inward
and
downward
against
the
glass.
If
the
reticle
is
to
be
temporarily
installed,
bend
the
metal
lip
in
at
three
points
around
the
glass.
If
the
reticle
is
to
be
permanently
installed,
bend
the
metal
lip
in
at
three
points
to
hold
the
reticle
disc
in
place.
Then,
holding
the
mount
at
a
45°
angle
roll
it
on
a
hard
sur
face
(such
as
a
table
top)
to
establish
metal-glass
contact
around
the
entire
circumference
of
the
mount.
4.
Replace
the
diaphragm
and
reticle
assem
bly
by
screwing
it
in
until
the
scale
comes
into
sharp
focus.
5.
To
remove
the
reticle,
press
against
the
scale
side
of
the
disc
and
push
the
reticle
out
of
its
mount.
Calibrating
the
Reticle
The
reticle
must
be
calibrated
for
each
Magnification
Knob
Setting
(and
attachment
lens)
it
is
used
with.
If
the
reticle
is
to
be
calibrated
in
inches.
Cat.
No.
31-16-89
or
31-16-87
Stage

should
be
used.
If
the
reticle
is
to
be
calibrated
in
milli
meters,
Cat.
No.
31-16-90
Stage
Micrometer
should
be
used.
For
the
most
accurate
calibration
and
sub
sequent
measurements,
the
Stage
Micrometer
and
reticle
should
both
be
positioned
in
the
north-south
direction.
1,
Insert
a
reticle
in
the
right
Eyepiece
and
place
the
appropriate
stage
micrometer
on
the
stage.
2,
Focus
carefully
so
that
both
the
stage
micrometer
scale
and
the
reticle
scale
are
sharply
in
focus.
If
the
reticle
scale
does
not
appear
focused
at
the
same
time
the
stage
micrometer
does,
readjust
the
eyepiece
diaphragm
position,
3.
Align
the
reticle
scale
with
the
stage
micrometer
scale
so
that
they
may
be
compared.
4.
Read
the
number
of
scale
intervals
"b"
on
the
stage
micrometer
which
corre
spond
to
the
number
of
intervals
"a"
on
the
reticle.
One
interval
of
the
reticle
then
corresponds
to
f
intervals
of
the
stage
micrometer.
Compute
this
ratio
and
use
it
to
make
measurements
in
the
specimen
plane.
Special
Reticles
Often
industrial
or
experimental
applications
require
special
custom
made
scales
such
as
a
"GO"
-
"NO
GO"
Gauge.
Bausch

Illuminator
The
type
of
illuminator
chosen
is
deter
mined
by
the
type
of
specimen,
the
area
of
the
specimen
which
must
be
illuminated
and
the
intensity
of
the
desired
illumination.
Whenever
possible,
mount
the
illuminator
to
the
microscope
so
that
the
illumination
stays
centered
as
the
microscope
is
focused
on
specimens
of
different
thickness.

VERTICAL
ILLUMINATOR
-
If
straight

any
of
the
illuminators
may
be
used
in
combination
with
the
Vertical

Unlike
the
other
illuminators,
the
Vertical

Illuminator
has
no
light
source
of
its
own.
Instead
it
has
a
mirror
system
which
reflects

is
especially
useful
for
examining
interior
surfaces
of
castings
or
machined
parts,
cracks,

The
Vertical
Illuminator
Adapter
is
attached
to
the
31-27-34
Converter
by
screwing
it
on.
Then
the
housing
of
the
Vertical
Illuminator
is
attached
to
the
Adapter,
oriented
as
necessary
and
clamped
in
place
by
the
set
screw.
For
examining
a
highly
polished
speci
men,
a
diffuse
source
of
light
such
as
the
Reflector
Illuminator
is
the
best
type
to
use.
It
should
be
placed
as
close
as
possible
to
the
side
aperture
of
the
Vertical
Illuminator.
If
the
resulting
images
in
the
microscope
eyepieces
are
of
uneven
intensity,
move
the
light
source
so
as
to
balance
the
reflected
light
from
the
specimen
to
each
side
of
the
microscope.
When
you
are
examining
a
specimen
with
a
rough
surface,
the
best
light
source
to
use
is
the
Nicholas
Illuminator.
It
should
be
attached
to
the
Power
Pod
by
means
of
the
adjustable
linkage
and
aimed
directly
into
the
side
aperture
of
the
Vertical
Illuminator.
ADJUSTMENT
AND
MAINTENANCE
LUBRICATION
The
Power
Pod
is
permanently
lubricated
at
the
factory
and
requires
no
periodic lubrica
tion.
The
focusing
slide
in
the
stand
should
occasionally
be
wiped
clean,
using
a
solvent
such
as
Xylol
or
alcohol,
and
relubricated
with
a
light
coating
of
grease.
Use
either
Bausch
&
Lomb
#PG-2
or
Alvania
#2
which
is
available
at
Shell
service
stations.
An
occasional
cleaning
of
the
rack
teeth
with
a
small
stiff
brush
is
recommended,
followed
by
relubrication.
CLEANING
THE
OPTICS
The
Power
Pod
has
been
factory
aligned,
cleaned
and
sealed,
DO
NOT
attempt
to
dis
assemble
it.
Within
each
eyepiece
adapter
tube
is
a
glass
dust
cover.
The
eyepieces
should
be
kept
in
place
to
prevent
dust
from
settling
on
these
covers.
However,
if
dust
does
accumulate
it
can
be
removed
by
unscrewing
the
eyepiece
adapter
and
wiping
the
lens
shields
with
a
soft
clean
cloth.
If
the
dust
is
gritty,
it
should
be
blown
off
with
an
air
syringe
or
wiped
off
with
a
damp
cloth
or
cotton
swab.
The
objective
lens
should
also
be
cleaned
with
a
soft
clean
cloth.
If
a
lens
has
grease
on
it,
clean
it
with
mild
soap
or
detergent
and
water
followed
by
a
thorough
wiping
with
a
dry
cotton
swab.
ADJUSTING
FOCUS
TENSION
Both
arms
and
all
stands
except
the
Series
S
and
Series
SK
have
two
Allen-head
screws
which
can
be
used
to
adjust
the
tension
of
the
focusing
mechanism.
By
turning
these
screws
slightly
clockwise
or
counterclock
wise
the
tension
can
be
increased
or
de
creased.
When
making
this
adjustment,
be
sure
to
move
the
screws
in
the
same
direction
and
about
the
same
amount.
