Like anyone who uses an anti newton glass carrier with films like Tmax 100 or Acros 100, you quickly find out that you also need some form of anti reflection coating on the emulsion side as well due to how smooth the films are on both sides. Luckily I have been able to use the glassless carrier with 4x5 TMX and TMY because of the fantastic base laying so flat in that nice LPL carrier, even at 20x24. But the smaller negs are when the PITA comes in... So I am trying to upgrade the 4x5 AN glass carrier for my LPL with some form of UV type glass rather than standard AN glass on the bottom. True-Vue Museam glass comes up quite a bit as a solution and they do make it for scientific type applications too with thickness of 1.2-12mm but that would be crazy expensive unless you wanted to do a bulk order and then sell them. So the top glass on my carrier is 1.65mm thick and the bottom is 1.77mm, for anyone who has used True-Vue glass, how did you get it fitted and how did you source it? There are several sources on ebay that sell it in cost effective quantities and sizes but I have no idea what the thickness is, I have written a couple of them in regards to that. Any pointers for this? Since I am also printing 6x6 and 6x12 in the same carrier, it has to be glass on both sides, and the bottom will have to be some form of UV glass.
