FEATURES

OF

THE

OMEGA

C760

DICHROIC

AND

DIFFUSION

LAMPHOUSES

Versatile

In

keeping

with

Omega’s

traditional

policy

of

non-

obsolescence,

your

C760

Lamphouse

can

be

used

on

a

wide

range

of

medium-format

Omega

enlargers,

both

current

and

eariler

models.

Your

C760

Lamphouse

can

be

used

with

C760,

C700,

B600,

Concept

Six,

B66,

B22

or

C67

enlarger.

The

only

requirement

is

suitable

mounting

hardware.

This

means

that

even

if

you

change

enlarger

chassis

later

on,

you

can

still

use

your

C760

Lamphouse

simply

by

getting

the

appropriate

hardware

(Page

5).

Expanded

Filtration

Range

(Dichroic

Lamphouse

Only)

The

filtration

range

of

the

C760

Dichroic

Lamphouse

is

from

0

to

200CC,

using

special,

non-fading

dichroic

glass

filters

which

produce

remarkably

“pure”

colors

in

cyan,

magenta

and

yellow.

Extremely

accurate

color

settings

are

obtained

permitting

consistent

and

precisely

repeatable

color

filtration.

(Page

13)

Even

Illumination

By

using

a

specially

designed,

pre-focused

85-watt

Quartz

Halogen

Lamp

with

integral

reflector

and

a

scientifically

designed

mixing

chamber

with

interchangeable

tapered

diffusers,

your

C760

Lamphouse

provides

exceptionally

even

illumination

on

your

baseboard.

This

means

that

print

densities

at

the

center

of

the

image

and

at

the

corners

will

be

almost

the

same.

(Page

12)

High

Light

Output

The

efficient

design

of

your

C760

Lamphouse

means

higher

light

output

for

shorter,

more

convenient

printing

times

even

at

extreme

magnifications.

This

high

light

output

also

permits

exposures

in

the

optimum

ranges

of

times,

from

5

to

40

seconds,

to

minimize

the

dangers

of

color

shift

resulting

from

unusually

long

exposures.

The

high

light

output

in

conjunction

with

our

reversible

girder

makes

possible

floor

projection

for

mural

size

prints.

White

Light

Control

(Dichroic

Lamphouse

Only)

A

special

white

light

lever

quickly

removes

the

dichroic

filters

from

the

light

path

without

disturbing

the

filter

settings.

This

permits

accurate

focusing

and

baseboard

composition

by

white

light.

An

illuminated

jewel

indicates

that

dichroic

filters

are

removed

from

the

light

path.

(Page

12)

Special

Light

Attenuators

To

provide

more

complete

control

over

light

output,

interchangeable

light

attenuators

are

supplied

and

can

be

used

to

reduce

the

light

by

one,

two

or

three

fistops.

This

permits

using

optimum

aperture/

exposure

time

combinations

for

convenient

exposure

or

use

of

creative

controls

such

as

dodging

and

burning-in.

(Page

Attenuators

supplied

with

dichroic

lamphouse

and

as

an

optional

accessory

(Cat.

No.

lamphouse.

Diffused

Illumination

for

Black-and-White

Printing

Many

of

today’s

outstanding

photographers

prefer

to

use

diffused

light

for

black-and-white

enlargements

rather

than

the

conventional

condenser

illumination.

One

reason

is

that

diffused

light

tends

to

produce

a

full

range

of

subtle

tones

with

great

accuracy.

In

addition,

diffused

light

serves

to

minimize

graininess

and

“supress”

minor

imperfections,

dust

and

scratches

on

the

negative,

greatly

reducing

the

need

for

retouching.

(Page

14)

Built-In

Infra-Red

and

Ultra-Violet

Filtration

Both

IR

and

UV

emissions

can

affect

the

color

of

your

final

print

even

though

these

rays

are

invisible.

Your

C760

Lamphouse

filters

out

these

emissions

so

that

the

desired

filtered

light

reaches

the

paper,

resulting

in

more

accurate

control

of

final

print

color.

Built-In

Solid

State

Power

Supply

Eliminates

the

need

for

external

transformer

or

power

supply.

You

can

simply

connect

your

C760

Lamp-

house

to

an

Omega

enlarging

timer

or

to

any

con-

venient

standard

110V

60Hz

AC

outlet,

or

240V

50Hz

outlet

depending

on

unit

purchased.*

*Recommended

Optional

Accessory:

For

the

most

precise,

consistent

color

printing

regardless

of

power

fluctuations,

the

use

of

the

solid

state

Voltage

Stabilizer

(Cat.

No.

403-730)

is

strongly

recommended

for

the

110V

60Hz

only.

The

240V

50Hz

units

have

the

stabilizer

built

into

the

lamphouse.

Flow-Through

Convection

Cooling

System

A

combination

of

cooling

fins

and

light-traps

provides

convection

cooling

for

greater

comfort

and

for

reduction

of

heat

on

the

negative,

thus

helping

prevent

negative

buckling.

Convertible

for

Slide

Duplication

(Dichroic

Lamphouse

Only)

By

simply

inverting

your

C760

Dichroic

Lamphouse

on

the

baseboard,

you

have

an

ideal

lightbox

with

complete

color

control

for

duplicating

color

sides.

You

can

use

the

full

range

of

CC

settings

for

color

correction

or

to

create

unusual

effects.

In

order

to

provide

even

illumination

over

the

en-

tire

negative

area,

and

to

minimize

light

leakage

around

stage,

you

must

align

the

lamphouse.

To

align

the

lamphouse,

attach

the

lamphouse

to

a

power

source

—

either

a

timer,

a

so

that

the

lamphouse

rests

on

the

film

stage.

8.

Loosen

the

hexagonal

nut

on

the

mounting

bracket

slightly

and

adjust

the

C760

Lamphouse

so

that

the

light

seals

at

the

bottom

make

contact

with

the

film

carrier.

The

edges

of

the

film

carrier

should

be

square

within

the

light

seal

as

shown

in

illustration

below.

When

the

lamphouse

is

correctly

aligned,

you

should

not

be

able

to

see

any

significant

light

leakage

between

the

lamphouse

and

the

film

carrier.

At

this

point,

tighten

the

hexagonal

to

secure

the

lamphouse.

Switch
