Attaching

the

lamp

bulb

The

microscope

is

delivered

with

its

lamp

bulb

(100V,

115/125

or

220/240V-30W)

attached.

If

it

is

necessary

to

replace

the

bulb

at

a

later

time,

proceed

as

below;

Be

sure

to

remove

the

power

cord

from

the

socket,

beforehand.

1)

Lay

the

instrument

down

carefully

to

permit

unscrewing

the

set

screw

found

on

the

bottom

lid

of

the

microscope.

A

screw

driver

or

coin

may

be

used.

2)

Sliding

the

bottom

lid

to

the

side

of

the

set

screw,

remove

it.

The

lamp

bulb

will

then

be

accessible.

(Fig.

3)

To

attach

the

bulb,

pushing

the

lamp

bulb

with

its

silver

surface

turned

to

the

side

of

the

bottom

lid

insert

the

bulb

into

the

socket.

(Fig.

13)

Note:

Finger

marks

left

on

the

lamp

bulb

sur¬

face

will

decrease

the

brightness

of

image.

In

handling

the

bulb,

use

a

cloth

or

wear

gloves.

4)

Replace

the

bottom

lid.

OBSERVATION

1.

Setting

the

specimen

in

position

1)

Place

the

specimen

on

the

stage

holding

in

position

by

means

of

the

slide

holder.

{Fig.

15)

2)

When

not

using

the

mechanical

stage,

hold

the

specimen

securely

with

the

two

stage

clips.

(Fig.

16)

2.

Adjusting

the

illumination

1)

Insert

the

power

cord

into

the

socket.

2)

Raise

the

condenser

to

its

upper

limit,

and

fully

open

the

condenser

diaphragm.

3)

Turn

the

power

switch

&

brightness

control

dial

to

light

the

lamp,

(Fig.

17)

Brightness

is

increased

by

turning

toward

the

thicker

end

of

the

arrow,

and

decreased

to¬

ward

the

thinner.

4)

Rotate

the

revolving

nosepiece

to

swing

the

4X

or

10X

objective

into

the

optical

path.

At

this

time,

make

sure

that

the

objective

clicks

properly

into

position,

3.

Adjusting

interpupillary

distance

(Fig.

18)

When

using

a

binocular

eyepiece

tube,

adjust

the

interpupillary

distance,

so

that

both

the

right

and

left

viewfields

become

one.

4.

Adjusting

for

eyesight

difference

(Fig.

19)

1)

First,

viewing

into

the

right

eyepiece

with

the

lOX

objective

in

position,

manipulate

the

coarse

and

fine

focus

knobs

to

bring

the

specimen

into

focus.

2}

Then,

viewing

into

the

left

eyepiece,

turn

the

diopter

ring

to

bring

the

image

into

sharp

focus,

without

manipulating

the

focus

knobs.

0

Coarse

focusing

1)

The

coarse

focus

knob

is

to

be

used

for

coarse

focusing

and

for

fine

focusing

with

the

4X

objective.

2)

It

can

also

be

used

for

lowering

the

stage

convenience

when

replacing

a

specimen,

removing

immersion

oil.

etc.

3)

The

relation

between

the

direction

of

rota¬

tion

of

the

coarse

focus

knob

and

that

of

vertical

movement

of

the

stage

is

as

indicat¬

ed

by

the

arrows

in

Fig.

.

Fine

Focusing

1)

The

fine

focus

knob

is

to

be

used

for

fine

focusing

with

the

10X

or

higher

power

objectives.

2

)

It

is

also

used

when

exchanging

objectives

or

focusing

on

each

successive

layer

of

a

thick

specimen,

3)

The

relation

between

the

direction

of

rota¬

tion

of

the

fine

focus

knob

and

that

of

ver¬

tical

movement

of

the

stage

is

the

same

as

for

the

coarse

focus

knob.

{Fig.

20-A.

B)

4)

The

range

of

the

fine

focus

knob

is

2.2mm.

The

white

line

on

the

fine

focus

knob

shows

the

center

of

the

fine

focusing

range.

It

is

necessary

beforehand

to

position

the

white

line

on

the

fine

focus

knob

opposite

the

end

of

the

coarse

focus

knob.

(Fig.

21)

Working

distance

of

objectives

1)

"Working

distance"

is

the

clearance

between

the

front

of

objective

and

the

upper

surface

of

the

coverglass

when

the

image

of

the

specimen

is

in

sharp

focus.

In

this

microscope

it

is

as

follows

for

each

objective:

Objective

Working

distance

4XSC.28mm

lOXSC.8mm

40XSC.0.73mm

lOOXSC.0.16mm

2}

As

shown

above,

the

working

distances

of

the

40x

and

100X

objectives

are

very

small,

incurring

the

danger

of

pressing

on

the

specimen.

These

two

objectives,

therefore,

are

specifically

equipped

with

a

safety

de¬

vice,

which

permits

rising

of

the

front

of

objective,

at

the

moment

it

touches

the

specimen.

Fig.

3)

T

o

proceed

to

focusing,

first

raise

the

stage

to

the

approximate

working

distance

of

the

objective

being

used.

Then,

viewing

into

the

microscope,

lower

the

stage

sicwviy,

until

the

image

is

brought

into

sharp

focus,

.

Vertical

1)

For

general

use,

raise

the

condenser

to

its

upper

limit.

2

)

When

examining

non-stained

specimens,

it

is

preferable

to

lower

the

condenser

to

such

an

extent

that

a

sufficient

image

contrast

is

ob¬

tained,

rather

than

to

close

the

condenser

diaphragm,

because

it

has

an

advantage

that

the

contrast

and

brightness

do

not

change

so

abruptly

and

greatly.

9.

Condenser

diaphragm

The

condenser

diaphragm

is

intended

to

adjust

its

numerical

aperture

(N.A.)

and

not

the

bright¬

ness

of

illumination.

1)

When

closed,

the

condenser

diaphragm

will

increase

the

image

contrast

but

decrease

the

resolving

power.

If

excessively

closed,

it

causes

fringes

visible

at

the

edge

of

image

details.

2)

Opening

of

the

diaphragm

is

continuously

adjustable

within

a

range

from

2.2mm

to

30

mm

in

diameter.

For

general

use,

it

should

be

stopped

down

to

70~80%

of

the

nu¬

merical

aperture

of

the

objective

to

achieve

an

appropriate

image

contrast.

For

adjust¬

ment

of

the

diaphragm,

when

observing,

turn

the

diaphragm

control

ring

so

as

to

obtain

an

image

quality

suitable

for

the

specimen.

10.

O

il-immersion

observation

(Fig,

21)

When

using

the

100X

objective

marked

with

a

black

ring,

the

specimen

should

be

immersed

in

oil

by

applying

Nikon

immersion

oil

between

the

coverglass

and

the

front

lens

of

the

objective.

Fig.

22

1)

Using

a

10X

or

40X

objective

focus

on

the

specimen.

Bring

the

desired

detail

in

the

specimen

to

the

center

of

the

field

of

view.

2)

Turning

the

revolving

nosepiece,

place

the

100

X

objective

in

a

position

where

it

is

con¬

venient

to

apply

oil.

Then,

tilt

the

oil

con¬

tainer,

until

oil

enters

the

nozzle.

Depressing

the

container,

attach

an

appropriate

amount

of

oil

onto

the

coverglass.

(Fig.

221

The

oil

may

take

in

air

bubbles.

If

any

air

bubble

is

seen,

clear

off

the

oil

using

lens

tissue,

and

apply

the

oil

once

again.

31

Thereafter,

keeping

the

container

depressed,

apply

the

oil

on

the

top

end

of

the

nozzle

to

that

of

the

objective.

Then,

rotate

the

100X

objective

into

the

optical

path.

4)

If

air

bubbles

enter

the

oil

layer,

a

poor

image

will

result.

To

remove

the

air

bubbles,

turn

the

revolving

nosepiece

several

times

laterally

or

apply

an

additional

drop

of

oil.

5)

If

a

higher

resolving

power

is

desired,

also

apply

oil

between

the

bottom

of

the

glass

slide

and

the

condenser

top

lens.

Note:

For

cleaning

the

oil,

after

finishing

oil-

immersion

observation,

wipe

it

off

thoroughly

with

lens

tissue.
