SLIT

LAMP,

MODEL

SL-6E

1)

The

convenient,

one

position

control

lever

allows

the

base

to

be

guided

freely

in

fine

cross-slide

adjustment

and

vertical

movement.

2)

The

convergent

binocular

tubes

allows

easy

and

natural

stereoscopic

observation.

3)

Camera

can

be

attached

without

cluttering

microscope

area

and

without

hamper-

ing

slit

lamp

operations.

4)

Unit

construction

photographic

system

and

observation

tube

makes

attachments

and

exchanges

very

simple.

5)

Stereophotographs

can

be

taken

very

easily,

with

one

shot,

by

simply

exchanging

the

normal

photographic

attachment.

6)

Five

magnification

changes

for

observation

and

photography,

with

higher

magni-

fication

also

possible

by

interchanging

eyepieces.

7)

Photographs

are

possible,

with

simple

auto-winding

operations,

by

simply

depres-

sing

the

release

button

on

the

joystick

control

lever.

8)

Background

illumination

can

be

added

to

the

slit

photograph,

as

well

as

adjusted

in

brightness.

9)

A

beam

splitter

unit

is

inserted

between

objective

and

the

prism

housings,

with

the

observation

tube

fixed

to

either

of

the

two

beam

splitter

mounts

on

the

unit.

As

in

the

case

of

the

photographic

unit,

the

optical

path

is

partially

diverted

only

when

the

observer

uses

a

lever

for

this

purpose.

10)

Goldmann

the

length

of

the

The

cross-scales

seen

in

the

field

of

view

of

one

of

the

eyepieces@

is

used

for

adjusting

the

eyepieces

to

the

user's

eyesight.

(The

cross-scales

can

be

placed

in

the

field

of

view

of

either

eyepiece,

as

found

suitable.)

The

eyepiece,

in

which

the

cross-scales

can

be

seen,

should

be

used

for

making

dioptric

adjustments

for

both

eyes

of

the

operator,

with

the

required

dioptric

power

for

the

other

eye

transferred

to

the

other

eyepiece.

Dioptric

adjustments

are

made

by,

first,

drawing

out

the

eyepiece

lens

fully,

by

re-

volving

the

eyepiece

adjustment

ring.

This

will

result

in

the

cross-scales

appearing

blurred

and

indistinct.

Next,

slowly

turn

the

eyepiece

adjustment

ring

in,

until

the

cross-

scales

are

seen

clearly

and

distinctly

and

then

stop.

If

the

eyepiece

adjustment

ring

is

revolved

beyond

the

point

of

clear

focus,

then

draw

the

eyepiece

lens

out

completely

once

and

repeat

the

adjustment.

The

eyepiece

adjustment

ring

has

a

dioptric

scale

engraved

on

it,

with

each

scale

division

representing

one

diopter.

If

you

can

remem-

ber the

dioptric

adjustments

for

both

eye-

pieces,

it

will

only

be

necessary

to

set

the

adjustment

rings

to

the

required

settings

on

the

scales

of

the

eyepieces,

without

going

through

the
