| The C760 is the most modern of the Omega
medium format enlargers. Introduced
towards the end of the enlarger boom that began in the 1970's, it
effectively replaced both the B66 and C67 enlargers. Incorporating many
design changes, it was strikingly different from the models it replaced. Instead of a baseplate, four
studs, extending from the corners of the girder, were bolted directly to
the baseboard, providing a very rigid column. Quick elevation changes
could be made via a spring-loaded, self-locking knob on the carriage,
with fine adjustments accomplished using an outer knob on the same
control. Dual left and right-hand focus controls were provided.
The
heads did not lift but were now fixed in position, minimizing alignment problems.
However, the head could be rotated, and the lens stage could be tilted
as well, providing distortion control. Negative
carriers were inserted against a spring loaded platform on the
carriage. Because enlarging lenses had pretty well standardized on
39mm mounting thread, it was possible to simplify the lens mount system
to just two threaded discs. Initially the C760 was offered in both
standard and XL length columns, but the shorter column was discontinued
by 1983. While the C760 chassis
has not been available for several years, the dichroic lamphouse and many accessories are still
current. Used Advice:
There are three potential problem areas which should be closely examined on
used C760 enlargers - the focus system, elevation mechanism, and condenser
lenses. Please refer to our C760 Service
Advisory for complete details. Also note our Technical Memo regarding
the C760 light seal. |
