A method for producing below 200 nm transmitting optical fluoride crystals includes loading a fluoride raw material into a vertical stack having at least 6 crystal growth chambers, heating the vertical stack to a temperature sufficient to maintain the fluoride raw material in a molten condition, applying a crystal growth thermal gradient to the vertical stack to form optical fluoride crystals within the molten fluoride raw material, and cooling the crystals.
