Not really. The Fluophot has a condenser with a flip up lens and no filter tray, as the design of it requires that any filter go on top of the condenser and between the top of the condenser and the flip up lens. I have managed to get a few cutout paper darkfield filters to work, but you have to lower the condenser, put the filter on top of the condenser, raise it again, then carefully position the filter using a toothpick to move it around. And a Rheinburg filter would need to be smaller than a dime to work. Your filter would have no room at all to fit in there.
