The standard D-D 4x5 light mixing chamber that comes with Omega's Super Chromega D Dichroic colorhead covers a full 5"x 5" area. Therefore, when working with smaller formats a good deal of the light output is wasted, and exposure times may become lengthy when making large prints. To improve light output for medium format negatives, Omega offers the optional D-B 6x7cm mixing chamber.
The used mixing boxes will have very minor cosmetic marks from previous use, but are in perfect working condition. A new liner kit has been installed, and the diffuser/attenuator panel and IR filter are in excellent condition.
