Abstract: A vacuum evaporation apparatus comprises a housing, in which a main vacuum cavity, a side vacuum cavity and a switch assembly are disposed. The main vacuum cavity is configured for vacuum evaporation. A tomography detection module for scanning a crucible to be measured and a manipulator for accessing a crucible in main vacuum cavity are disposed in the side vacuum cavity. A switch assembly is disposed between the main vacuum cavity and the side vacuum cavity. Where the switch assembly is opened, the main vacuum cavity and the side vacuum cavity are communicated with each other to enable accessing the crucible. Where the switch assembly is closed, the main vacuum cavity and the side vacuum cavity are separated from each other.
