OLYMPUS

This

instruction

manual

has

been

written

for

the

use

of

the

Olympus

Stereo

Microscopes

Models

VMF-W,

VMT-W

and

VMZ-W.

It is

recommended

that

you

read

the

manual

carefully

in

order

to

familiarize

yourself

fully

with

the

use

of

the

microscope

so

that

you

can

obtain

optimum

performance.

VII.

USE

OF

OPTIONAL

ACCESSORIES

IMPORTANT

Operation

1.

Always

handle

the

microscope

with

the

care

it

deserves

and

avoid

abrupt

motions.

2.

Avoid

exposure

of

the

microscope

to

direct

sunlight,

high

temperature,

high

relative

humidity,

dust

and

vibration.

Maintenance

1.

Lenses

must always

be

kept

clean.

Fine

dust

on

lens

surfaces

should

be

blown

or

wiped

off

by

means

of

an

air

blower

or

gauze.

Carefully

wipe

off

oil

or

fingerprints

deposited

on

the

lens

surfaces,

with

gauze

moistened

with

a

small

amount

of

xylene, alcohol

or

ether.

2.

Do

not use

organic

solutions

to

wipe

the

surfaces

of

various

components.

Plastic

parts,

especially,

should

be

cleaned

with

a

neutral

detergent.

3.

Never

disassemble

the

microscope

for

repair.

4.

The

microscope

should

be

stored

in

its

container

immediately

after

use.

If

this

is

not

possible,

it

should

be

covered

with

the

vinyl

dust

cover

provided.

It

is

best

to

keep

lenses

in

a

desiccator.

Stage

Plate

OPERATION

The

stage

plates

fit

into

the

circular

opening

in

the

base.

The

clear

plate

can

be

used

for

both

reflected

and

transmitted

illumination.

Colored

background

can

be

achieved

by

placing

suitable

material

beneath

the

plate,

for

contrast,

etc.

The

frosted

plate

is

used

with

reflected

illumination,

The

plate

is

frosted

white

on

one

side,

and

black

on

the

other.

If

the

specimen

is

white

or

brightly

colored,

use

the

black

side

of

the

plate

to

increase

image

contrast

by

darkening

the

background.

For

dark

or

black

specimens,

reverse

the

plate

with

the

white

frosted

side

facing

the

objective.

Tension

Adjustment

of

Focusing

Knobs

This

focusing

mechanism

makes

its

motion

freely

adjustable

for

either

heavy

or

light

movement

depending

on

the

observer's

preference.

To

adjust

the

tension

hold

the

two

focusing

knobs

with

both

hands

and

slightly

rotate

them

in

the

opposite

directions,

at

the

same

time.

(Fig.

1)

Place

a

specimen

in

the

center

of

the

stage

plate

and

clamp

it

with

the

stage

clips,

if

necessary.

(Fig.

Adjustment

Hold

the

right

and

left

eyepiece

tubes

with

both

hands

and

push

or

pull

the

tubes

in

the

arrow

directions

until

perfect

binocular

vision

is

obtained.

(Fig.

Diopter

Adjustment

a)

Looking

through

the

right

eyepiece

with

your

right

eye,

focus

on

the

specimen

with

the

focusing

knobs.

NOTE:

In

case

of

the

Model

VMT-W

or

Model

VMZ-W,

ascertain

that

the

high

magnifica-

tion

objectives

are

used

for

this

adjustment:

b)

Look

at

the

image

through

the

left

eyepiece

with

your

left

eye,

and

rotate

the

diopter

adjustment

ring

@

to

focus

on

the

specimen,

without

using

the

focusing

knobs.

(Fig.

4)

NOTE:

If

accurate

interpupillary

distance

and

diopter

adjustments

are

not

accom-

plished,

prolonged

observation

would

put

considerable

strain

on

the

observer's

eyes.

5.

Objective

Changes

The

Model

VMT-W

is

provided

with

two

objective

pairs.

Rotate

the

turret

until

the

objec-

tive

pair

of

your

choice

is

engaged.

In

case

of

the

Model

VMZ-W,

rotate

the

zoom

control

ring

until

you

obtain

the

desired

magnification

within

the

magnification

range.

6.

Use

of

Eyeshields

Eyeshields

are

recommended

to

prevent

glare

and

loss

of

contrast

caused

by

ambient

light

hitting

the

eye.

7.

Use

of

the

Reflected

Base

VM-ILA-2

a)

Water

sealed

b)

It

provides

illumination

with

all

objective

powers

except

c)

If

light

intensity

is

too

high,

it

can

be

reduced

by

Bulb

Replacement

*

Before

bulb

replacement,

be

certain

the

defective

bulb

is

cool.

1)

Pull

the

contact

pins

of

a

halogen

bulb

from

its

polyethylene

bag.

*

Be

careful

not

to

leave

fingerprints

or

smudges

on

the

bulb

portion.

2)

Insert

the

contact

pins

fully

into

the

socket

©.

(Fig.

6)

*

Do

not exert force

to

twist

or

bend

the

bulb, but

gently

push

the

pins

into

position.

*

Do

not

tilt

the

bulb

when

inserting

it

into

the

socket.

%*

Take

care

not

to

smudge

the

mirror

surface

(2)

with

fingerprints,

etc.

If

smudged,

the

mirror

should

be

wiped

clean

with

cotton

gauze

slightly

moistened

with

a

3:7

mixture

of

alcohol

and

ether.

3)

Looking

at

the

bulb

from

the

front,

confirm

that

the

fila-

ment

image

covers

the

lower

half

of

the

screw

head

on

the

mirror

surface,

(Fig.

7)

*

If

the

filament

image

is

deviated

horizontally

from

the

center

(since

the

bulb

tilts

in

either

direction),

adjust

the

bulb

position

correctly.

*

If

the

filament image

is

deviated

vertically,

the

contact

pins

are

not

inserted

completely.

Push

them

in

completely.
