EVAPORATED (AMORPHOUS) (STANDARD) CARBON FOILS: Thicknesses 1 nanometer to 5 micrometers, areal densities 0.2 to 1000µg/cm2, lateral dimensions 25mm x 69mm(stock) or 50mm x 69mm(stock) or customized to your specifications. REMOVABLE SUBSTRATES for foils' thicknesses lnm to lµm, areal densities 0.2 to 200µg/cm2. INSTRUCTIONS FOR MOUNTING are given for persons who want to mount their own. FREE-STANDING (no substrates needed) for foils' thicknesses 1µm to 5µm, areal densities 200 to l000µg/cm2. MOUNTED ON FORKS, washers or other mountings for your special applications. ISOTOPIC CARBON (C-12 AND C-13) FOILS available on special order. POLYCRYSTALLINE GRAPHITE FOILS: We handle two kinds: PCG (LOW-DENSITY) FOILS, density 0.8 - 1.2g/cm3, areal densities 0.4 to 10.0 milligrams/cm2, effective (bulk) thicknesses 2 to 50µm. BULK-DENSITY GRAPHITE FOILS, density 1.8g/cm3, thicknesses 25µm and up, areal densities 5mg/cm2 and up. METAL and ISOTOPIC FOILS: On removable substrates or free-standing, typical thicknesses 10nm to 2µm.

Mounted gold foil (75nm thick) and silicon foil (36nm thick) in front of carbon foil (25nm thick), 25cm diameter
