Omega D5500 Dichroic Lamphouse

The D5500 CLS Dichroic was Omega's offering of an innovative colorhead no longer based on mechanical cams and dials. The "closed loop system" microprocessor control provided print repeatability unmatched by other systems.

Control of the colorhead settings was from a convenient table level controller or translator/controller, connected to the lamphouse via a ribbon cable, with the controllers also providing timer functions. The unit automatically compensated for any change in color temperature, adjusting the filters to maintain the set filtration levels. Since filtration levels were electronically controlled, accuracy was improved compared to using the mechanical thumbwheels on the Chromega D Dichroic colorhead. The controllers also provided a computer interface port, the intention being that users could control the enlarger settings from a computer using custom software.

Used Advice: The D5500 Dichroic system has proven both reliable and efficient. Users have found that the benefits far outweigh any learning curve required. On used units, the electronics should be closely examined for proper operation. Early controllers with the membrane keypad were prone to keyboard failure. Conversion kits are still available, but not inexpensive.
