The vacuum vapour deposition apparatus for coating one side of an optical substrate comprises support means which rotate in an evacuable container above at least one vapour source. The support means comprise a plurality of at least approximately circular segment-shaped pivotable support plates which are positionable cup-like relative to each other and are supported on a common rotating axle, each pivotable about 180.degree.. Each of said pivotable support plates has support areas on both sides with means for clamping securely a plurality of substrates which are to be coated on one side and which sit on the respective supporting areas.
