The refractive index of the oil has to be close to the that of the glass
in order for it to work. I believe that one microscope immersion fluid
is 2-bromonaphthalene. Anything appropriate will be a mess to clean up.

Subject: [pure-silver] Oil/Solvent Immersion Enlarging
Recently I've experimented with scanning wet-mounted 35mm negatives to a
glass plate using Kami fluid and mylar. This produced sharper scans
with less grain and dust spots than 'dry' scanning, and I'm considering
trying a similar technique with my enlarger. I know that there have been
oil immersion carriers made for some enlargers, and so someone must have
some experience with this. Has anyone here done this? What were your
results? Since Kami fluid is a solvent which is meant to evaporate
fairly quickly, I expect that using it near a 250 watt halogen bulb
might not be a good idea. Does anyone have a suggestion for a good
alternate fluid? Would mineral oil work?
