Material Holders for High-Vacuum Thin Film Coatings
Hold and heat coating material to extremely high temperatures for use in high-vacuum thin film coating processes. Also known as physical vapor deposition (PVD), thin film coating creates micron-thin, consistently smooth finishes on knobs, mirrors, and other objects.
These holders are designed for use with metal coating hooks and pellets. Hang a hook of coating material on a wire coil or place pellets of material in a basket or in a bowl. Wire coils and wire coil baskets allow the vaporized particles to travel in any direction. Bowls with flat end plates and wire coil baskets with crucible direct the vaporized particles upward.
A holder's material and thickness determine the amount of electricity required to heat it. In general, the thicker the holder, the greater the amount of electricity needed to heat it. As a reference, required current describes what is necessary to heat these holders to a given temperature. Exact values will depend on your application.
