Introduction

Image

excellence,

rugged

construction

and

exceptional

versatility

are

the

hallmarks

of

the

Bausch

&

Lomb

StereoZoom

series

of

stereo

microscopes.

These

features

are

in

keeping

with

a

tradition

of

quality

Bausch

&

Lomb

has

maintained

for

more

than

100

years

as

a

microscope

manufacturer.

The

StereoZoom

series,

introduced

by

Bausch

&

Lomb

in

the

1950's, has

become

the

world

standard

for

stereo

microscopes.

Since

its

introduction,

the

StereoZoom

series

has

undergone

constant

improvements

and

expansion

through

the

development

of

new

models

and

accessories.

Interchangeability

between

Power

Pods,

Stands,

Eyepieces,

Supplementary

Lenses

and

a

host

of

special

accessories

provides

the

user

with

a

nearly

limitless

choice

of

feature

combinations

which

permit

the

exact

tailoring

of

the

StereoZoom

equipment

to

the

requirements

of

the

task.

The

StereoZoom

series

can

be

used

to

advantage

for

nearly

any

visual

task

requring

3-D

observation

at

moderate

magnifications.

Frequently,

the

StereoZoom

series

offers

the

most

economical

approach

to

providing

microscope

magnification

even

when

there

is

no

requirement

for

3-D

observation.

Six

Power

Pods

form

the

nucleus

of

the

StereoZoom

series.

Two

of

these

are

fixed

power

while

four

of

them

provide

continuously

variable

magnification

by

means

of

operator

controlled

zoom

systems.

Eyepieces

and

Supplementary

Lenses

extend

the

magnification

ranges

of

these

Power

Pods

both

upward

and

downward.

All

optical

elements

are

sealed

into

the

Power

Pods

so

that

all

Pods

may

be

interchangeably

mounted

on

any

one

of

the

thirteen

Stands

and

Arms

offered

as

part

of

the

StereoZoom

series.

For

viewing

convenience,

the

Pods

may

be

turned

180

degrees

for

conventional

or

reversed

eyepiece

orientation.

Other

accessories

include

a

wide

choice

of

illuminators and

illumination

modes,

mechanical

stages

and stage

plates,

polarizing

accessories,

reticles

and

photographic

equipment.

Selection

of

the

right

combination

of

components

involves

consideration

of

cost,

magnification

range,

field

of

view,

working

distance,

eye

relief,

specimen

illumination

requirements

and

convenience

of

use.

With

this

in

mind,

descriptive

data

on

the

StereoZoom

series

components

are

presented

in

Section

9.0

of

this

manual

both

to

assist

you

in

interpreting

the

instructions

presented

here

and

to

help

you

more

fully

utilize

the

StereoZoom

equipment

you

already

have

purchased.

For

more

detailed

information,

the

latest

edition

of

Bausch

MEASURING

PROCEDURE

StereoZoom

Microscopes

may

be

used

as

measuring

instruments

by

inserting

a

Reticle

in

one

of

the

Wide

Field

Eyepieces.

À

variety

of

linear

and

grid

patterned

Reticles

are

available

for

particualr

applications

as

well

as

Stage

Micrometers

for

calibrating

the

microscope.

These

are

described

in

Section

9.0.

SELECTING

A

RETICLE

DISC

Select

the

magnification

that

will

enable

you

to

see

the

necessary

detail

and

yet

cover

as

much

total

area

of

the

specimen

as

is

required.

Greatest

accuracy

will

result

from

measurements

made

within

the

central

%rds

of

the

field

of

view

in

a

north-south

direction.

After

the

magnification

has

been

selected

the

appropriate

reticle

disc

should

then

be

selected.

First,

decide

what

unit

you

desire

to

measure

the

specimen

by,

then

use

the

following

formula

to

determine

what

reticle

will

provide

that

unit:

SxM=K

Dimension

each

division

is

to

egual

in

the

specimen

plane.

M

=

Magnification

of

the

Power

Pod

only.

K =

Actual

dimension

of

each

smallest

division

on

the

reticle.

o

on

reticle

(egual

to

on the

specimen)

would

be

K

.004

(approximately

0.1mm).

INSERTING

THE

RETICLE

DISC

Caution

Before

installing

a

Reticle

be

sure

it

is

free

of

dust,

lint,

smears,

etc.

To

clean

the

Reticle

wipe

its

surfaces

with

a

cotton

pad

moistened

with

a

mild

soap.

Rinse

and

dry

without

pressure

using

a

soft

lintless

cloth.

1.

Remove

the

black

cylindrical

Field

Diaphragm

by

unscrewing

it

from

inside

the

smaller

diameter

end

of

the

Eyepiece

(refer

to

the

Assembly

Views

on

page

8.14).

2.

Place

the

Reticle

into

the

thin

metal

rim

on

top

of

the

Field

Diaphragm

so

that

the

scale

will

face

towards

the

inside

of

the

Field

Diaphragm.

3.

The

thin

metal

rim

will

extend

beyond

the

surface

of

the

glass.

Using

a

pencil

with

eraser,

or

thumbnail

or

similar

object,

press

against

the

outside

of

the

rim

to

force

it

inward

and

downward

against

the

Reticle.

If

the

Reticle

is

to

be

temporarily

installed,

bend

in

the

metal

rim

at

three

points

around

the

glass.

If

the

Reticle

is

to

be

permanently

installed,

do

this

at

three

points

around

the

circumference

and

then

bend

the

rim

over

the

Reticle

around

the

whole

circumference

by

holding

the

mount

at

a

45°

angle

and

rolling

itona

hard

surface

such

as

a

table

top.

4.

Replace

the

Field

Diaphragm

and

Reticle

assembly

by

screwing

it

in

until

the

scale

comes

into

sharp

focus

when

viewed

through

the

Eyepiece.

5.

To

remove

the

Reticle,

press

against

the

scale

side

of

the

Reticle

and

push

it

out

of

its

mount.

CALIBRATING

THE

RETICLE

After

the

correct

Reticle

has

been

selected

it

must

be

calibrated.

If

the

Reticle

is

to

be

calibrated

in

inches

a

31-16-89

or

31-16-87

Stage

Micrometer

should

be

used.

If

the

Reticle

is

to

be

calibrated

in

millimeters

a

31-16-90

or

31-16-99

Stage

Micrometer

should

be

used.

For

the

most

accurate

calibration

and

measurements,

the

Reticle

and

the

Stage

Micrometer

both

should

be

positioned

in

the

north-south

direction.

The

Reticle

must

be

calibrated

for

each

objective

power

that

it

is

used

with

and

must

also

be

calibrated

for

each

StereoZoom

microscope

that

it

is

used

with.

4.

It

is

recommended

that

the

Eyepiece

containing

the

Reticle

be

placed

in

the

right

Eyepiece

Adapter.

2.

Place

the

appropriate

Stage

Micrometer

on the

Microscope

Stage

Plate.

3.

Focus

carefully

so

that

you

see

the

Stage

Micrometer

scale

sharply

in

focus

at

the

same

time

as

the

Reticle

scale

is

sharply

in

focus.

4.

Align

the

Reticle

scale

with the

Stage

Micrometer

scale

so

that

they

may

be

compared.

.

Read

the

number

of

scale

intervals

“b”

on

the

Stage

Micrometer

which

correspond

to

the

number

of

intervals

“a”

on the

Reticle.

One

interval

of

the

Reticle

then

corresponds

to

b/a

intervals

of

the

Stage

a

5.1

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

Reticle

that

could

be

used

as

a

“GO

-

NO

GO”

gauge.

Maintenance

&

Service

PROTECTING

THE

MICROSCOPE

AND

ACCESSORIES

The

primary

rule

to

follow

with

respect

to

proper

care

of

microscopes

and

accessories

is

to

keep

them

as

free

from

dust

and

dirt

as

possible.

Dust,

fingerprints

or

a

smear

on

the

optics

will

degrade

the

image.

When

the

equipment

is

not

in

use,

cover

it

with

a

plastic

cover.

CLEANING

THE

OPTICS

The

Power

Pods

have

been

factory

aligned,

cleaned

and

sealed.

DO

NOT

attempt

to

disassemble

them.

Within

each

Eyepiece

Adapter

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

dust

cover

with

a

soft

clean

cloth.

If

the

dust

is

gritty,

it

should

be

blown

off

with

an

air

syringe

or

wiped

off

with

a

cloth

or

cotton

swab

moistened

with

soap

and

water

or

alcohol

followed

by

a

thorough

wiping

with

a

dry

cotton

swab.

CAUTION

Avoid

excessive

use

of

solvents,

as

flowing

solvents

may cause

cement

run-in

on

cemented

optics,

making

cleaning

a

tedious

job.

ADJUSTING

FOCUS

TENSION

ON

ARMS

AND

STANDS

Both

Arms

and

all

Stands

except

the

R,

S

and SK

Stands

have

two hex

socket-head

Gib

Screw

B's

which

can

be

used

to

adjust

the

tension

of

the

focusing

mechanism.

By

turning

these

screws

slightly

clockwise

or

counterclockwise,

the

tension

can

be

increased

or

decreased.

When

making

this

adjustment,

be

sure

to

adjust

the

screws

in

the

same

direction

and

about

the

same

amount.

Each

R

Stand

is

factory

adjusted

to

establish

the

proper

balance

between

the

tension

of

the

focusing

mechanism

and

the

load

carrying

capacity.

After

considerable

use,

a

slight

readjustment

may

be

needed.

To

increase

the

focusing

tension,

tighten

the

hex

socket-head

screw

in

the

center

of

the

left

Focusing

Knob

about

1/12

of

a

turn

clockwise

using

a

7/64-inch

hex

wrench.

To

decrease

the

tension,

loosen

the

screw

about

1/2

turn

counterclockwise

and

pull

the

left

knob

outward

to

reduce

the

tension.

Then

tighten

the

screw

gradually

until

the

desired

tension

is

established.

LUBRICATION

Power

Pods

and

R

Stands

are

permanently

lubricated

at

the

factory

and

generally

do

not

require

periodic

6.0

lubrication.

If

cleaning

and

relubrication

become

necessary

as

a

result

of

abnormal

use

or

exposure

to

unusually

harsh

environments,

the

equipment

should

be

returned

to

the

factory

or

serviced

by

qualified

maintenance

personnel.

The

Focusing

Slide

on

all

stands

other

than

R

stands

should

be

wiped

clean

occasionally,

using

a

solvent

such

as

Xylol

or

alcohol,

and

relubricated

with a

light

coating

of

grease.

Alvania

+2

grease,

which

is

available

at

Shell

service

stations,

is

recommended

for

this

purpose.

SERVICE

All

optical,

electrical

and

mechanical

equipment

requires

periodic

servicing

to

keep

it

performing

properly

and

to

compensate

for

normal

wear.

Establishing

a

schedule

of

regular

preventive

maintenance

will

help

to

assure

long

life

and

sustained

optimum

performance

for

your

instrument.

It

will

also

help

to

avoid

unexpected

trouble

and

the

necessity

of

having

the

instrument

serviced

at

inconvenient

times.

A

program

of

planned

preventive

maintenance,

involving

a

thorough

cleaning,

checking

and

adjustment

of

mechanisms

is

recommended

for

all

instruments.

This

work

should

be

performed

by

qualified

personnel

with

the

proper

training

and

equipment.

Your

authorized

B&L

dealer,

or

Bausch

&

Lomb,

can

arrange

this

service.

IMPORTANT

If

unexpected

trouble

is

experienced

with

your

instrument,

contact

your

Bausch

&

Lomb

dealer.

He

may

be

able

to

suggest

simple

remedies

to

correct

the

apparent

difficulty

without

your

having

to

send

the

instrument

out

for

servicing.

Should

it

become

necessary

to

send

your

instrument

out

for

service:

Please

pack

the

instrument

carefully

in

a

crush

resistant

carton

with

at

least

three

inches

of

shock

absorbing,

dustless

material

surrounding

it

to

prevent

transit

damage.

Saving

the

original

carton

in

which

your

instrument

is

received

will

prove

helpful

for

this

purpose.

If

a

suitable

carton

is

not

available,

one

may

be

ordered

from

the

factory

at

nominal

cost.

Include

a

detailed

letter

in

the

shipping

carton,

preferably

fastened

to

the

instrument,

describing

the

trouble

experienced.

This

information

will

enable

the

service

technician

to

effect

required

repairs

promptly

and

at

least

expense.
