Stokes vacuum coaters are used to deliver a vapor stream primarily metallic vapors) to a group of substrate work pieces. On contact the vaporized material condenses to a solid, forming a thin vacuum coating on the substrate. The system is composed of four major subsystems:

The Pumping System: Develops the proper vacuum level
The Chamber System: Houses the substrate holders and is where the "work" takes place
The Work Holding System: Is the carriage assembly; it holds the substrates arranged on a number of work reels
The Firing System: Consists of the electrical package for temperature development, the source holders and the coating sources

Stokes offers multi-step processes for applications such as automotive headlamps and ceiling louvers. Typical steps include: glow discharge cleaning, aluminum deposition, plasma polymerization, and silicon monoxide coating.
