Provided is a method of vacuum deposition to deposit at least two functional coatings to a substrate, including (a) evaporating a first film forming material from a first evaporation source disposed in a vacuum deposition chamber, (b) depositing the evaporated first film forming material on a substrate located above the first evaporation source to form at least a portion of an anti-reflective coating on the substrate, (c) evaporating a second film forming material from a second evaporating source disposed in the vacuum deposition chamber, and (d) depositing the evaporated second film forming materials on the substrate located above the second evaporation source to form a hydrophobic coating on the substrate.

Method for vapor deposition of optical substrate

The invention relates to a method of retrofitting a vacuum deposition chamber of an apparatus for coating optical substrates, the vacuum deposition chamber comprising a second resistance evaporator crucible. The method comprises installing a resistance evaporator comprising a crucible into the operational vacuum deposition chamber such that the crucible is disposed above the vacuum deposition chamber floor, and such that the second resistance evaporator crucible is closer to the vacuum deposition chamber floor than the installed crucible.
