The Gold Coated Thin Film Disk is a gold foil coated on a temporary/ removable polymer support. Available in 3 variations, gold coatings provide high reflectivity and conductivity while the thin film substrate offers mechanical strength and flexibility. Gold Coated Thin Film disks have applications in electronics as contacts or electrodes, and in optical devices thanks to gold's infrared reflectance. The variety of sizes and thicknesses we offer make these disks suitable for prototyping and research.
