Condensers for 4X5 Beseler M series enlargers. Slightly scratched set of 2, $50.
LIGHT BALANCING DIFFUSION DISK, for Omega or Beseler, 6 7/16" diameter, thicker in the center, simply replace your condensers with this or replace the opal plastic diffusion disk supplied with your Aristo or Zone IV cold light head. Think you don't need it? Guess again. Make a flash test by focusing on the negative plane and making a midtone grey print with no negative in the enlarger. You'll probably find that you have a serious hot spot in the center. This light balancing filter is a new item made by GLENNVIEW, available nowhere else, $100. Similar item in 5X7" format, $250. Similar item for Aristo model 810 cold light head, 8.75X10.75" in size, the largest size I can make, $400. Expect 1-2 stops less light ouput with this diffusion disk. The plastic in the 2nd photo has the paper that comes on it as new to protect it. You can see the paper through the edges of the disk because the plastic is thin at the edges. The plastic is smooth under the paper; that side goes down. The machined side goes up. Are you a machinist? Try machining a thin sheet of plastic. You will find it is not worth your time to learn how. I have sold these to Europe's largest photo equipment distributor. I never thought I would be selling a machined product to the Germans.
