Abstract
A direct vapor deposition (DVD) method and apparatus for applying coating(s) on substrate(s), including: presenting at least one of the substrates to a chamber, presenting at least one evaporant source () in crucible () to the chamber; presenting at least one carrier gas stream () to the chamber using a ring-shaped () converging/diverging nozzle (); impinging at least one evaporant source with at least one electron beam in the chamber to generate an evaporated vapor flux in a main direction respective for any of the evaporant sources impinged by the electron beam; and guiding at least one of the generated evaporated vapor flux by at least one carrier gas stream from the ring shaped gap (), which is essentially parallel to the main direction and substantially surrounds the evaporated flux. The evaporated vapor flux at least partially coats at least one of the substrates.
