Author Topic: Condensers Bill Enos Film God Posts: 2081 From: Richmond, Virginia, USA Registered: Apr 2000 posted 03-16-2001 12:03 AM                     Two of the condensers in our Brenographs have gotten extremely pitted. I buff them occasionally with a buffing wheel on a bench grinder using automative rubbing compound to improve them but they need replacing. They are 5 1/2 inches in diameter and have the usual convex side 1 3/8 inches high and the other side is concave 3/8 inch deep. there are two of these in eash lamp,only the one facing inside the lamp is pitted. The operation manual call it a double condensing system. Anybody know where these can be had? Wolk tossed a truck load several years ago when they moved so they are out. Any other suggestions?

I believe the URL is www.edsci.com/ . While your at it, you could place a thin piece of sheet glass between the condensers and the arc. that would protect the optics and you would only have to periodically replace the glass. much cheaper than replacing lenses Josh Ken Layton Phenomenal Film Handler Posts: 1452 From: Olympia, Wash.
