Optical

components

SV

6

and

SV

11

stereo

bodies

General

The

SV

6

and

SV

11

stereo

bodies

are

telescopic

systems.

They

have

a

main

objective

and

are

ideally

suited

for

flat

specimens.

The

two

separate

beam

paths

run

parallel

to

each

other

and

are

combined

by

the

objective

in

the

specimen

plane.

It

is

therefore

easy

to

attach

accessories,

such

as

a

drawing

tube,

an

intermediate

tube

or

a

coaxial

reflected-light

unit.

Both

stereo

bodies

feature

port

(1)

with

locking

screw

(2)

for

attaching

a

binocular

tube.

A

dovetail

ring

with

a

positioning

is

located

on

the

undersides

of

the

two

bodies

for

mounting

an

objective

S.

Screw

(4)

is

used

to

lock

the

objective.

SV

are

used,

a

total

of

is

obtained

(also

see

total

page

9).

Using

an

SW

3

screwdriver,

screw

(6)

can

be

turned

through

this

activates

or

deactivates

the

click-stop

If

an

objective

S

1.0x

and

eyepieces

are

used,

a

total

magnification

of

6x...66x

is

obtained

(also

see

total

To

override

the

click

stops,

you

can

rotate

screw

(6)

through

90°

using

an

SW

3

screwdriver.

Double

iris

diaphragm

(7)

is

used

to

enhance

the

image

contrast

and

the

depth

of

field.

This,

however,

reduces

resolution.

Objectives

A

wide

range

of

objectives

is

available.

Their

dovetail

makes

them

easy

to

change.

The

objectives

differ

in

their

focal

lengths

and

magnifications,

i.e.

their

free

working

distances

and

resolving

powers.

The

used

in

To

obtain

to

General

rules

=

The

illuminators

described

in

the

following

can

be

used

singly

or

in

combination.

Use

as

few

light

sources

as

possible.

Shadows

produced

by

several

light

sources

cause

unsteadiness

in

the

image.

It

is

possible

to

brighten

by

the

use

of

a

second

light

source.

=

Shadows

may

only

be

just

visible

and

no

more,

otherwise

they

will

appear

too

dark

in

the

photograph.

Shadows

may,

however,

be

used

to

advantage

to

judge

the

depth

of

the

image.

a

If

more

importance

is

attached

to

color

than

form

in

a

photograph,

the

illumination

must

be

set

to

produce

fewer

shadows.
