Thank you for selecting the Omega C760 Lamphouse.
Your C760 Lamphouse provides an extremely
versatile, high-output illumination system for your
Omega medium-format enlarger. Its many advanced
features give you the ability to produce finer prints in
color and in black-and-white quickly, consistently and
easily. You can even use your C760 Dichroic
Lamphouse as a light box for duplicating color slides.
Like every Omega product your C760 Lamphouse is
built to traditional Omega standards of quality and
performance. This means the finest materials,
meticulous workmanship and a design that is "human
engineered" for efficient, comfortable operation. Your
C760 Lamphouse should give you many years of
trouble-free service.

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)
