DM Lamphouse
 

DM
Point Light Source

Lamphouse

Introduced: 195x
Discontinued: 1981

 

The DM Point Light Source heads were created to provide high intensity light sources for special applications such as microfilm, engineering drawings, electron microscope negatives, Ektalith printing, etc. Three different heads were available to accommodate different focal length lenses, and a custom condenser set was required for each focal length. A variable transformer power supply was necessary since the enlarging lens was required to be at maximum opening at all times to prevent colour fringing.  The lamp could be adjusted vertically to ensure even light distribution at different magnifications.  Using the special BEV lamp, the DM was able to provide up to 60 times the light output of a conventional condenser lamphouse.

It was most often sold with D2, D3, and later, D5 chassis as Omega DM Microfilm Enlargers.

Used Advice:  The DM lamphouse is not intended for normal photographic printing, but is useful for high contrast work.  One should ensure that a used lamphouse is the correct type and has the correct condenser set for the intended format.  If in doubt, call us for additional information.
