A vacuum coating apparatus for coating films on the surfaces of objects to be deposited under vacuum is provided with a vacuum deposition chamber, a carrier accommodated in the vacuum deposition chamber for carrying the objects, a rotary mechanism extending through the vacuum deposition chamber and being rotatable with respect to the carrier, and a container mounted on the rotary mechanism and accommodated in the vacuum deposition chamber. The container accommodates a material to be evaporated and is rotated by the rotary mechanism during a deposition operation while the objects are maintained stationary.

In a vacuum vapor-deposition system a substrate holder is arranged stationary in the main part of a vapor-deposition chamber. Evaporation apparatuses are arranged on the floor of the vapor-deposition chamber, which is moveably connected to the main part of the vacuum-deposition chamber via a bellows and can swivel about two mutually intersecting axes or be displaced along two mutually intersecting axes with respect to the main part by means of two drive mechanisms. In this way the thermostatization of the substrate and the production of very uniform layers is facilitated.

An evaporator device system having an electron jet heating device for the vaporization of several materials onto a substrate in a vacuum chamber includes at least two crucibles for the reception of respective evaporation materials. These crucibles are concentrically arranged on a turntable. For the more uniform evaporation of the material, at least the crucible aligned with the electron jet is caused to rotate in the turntable during operation of the eletron jet heating device.
