CL Series Evaporation Source

The CL series evaporation source is specially designed for Al material evaporation. It adopts a bottle-shaped crucible and a double heating wire structure design. The upper and lower temperature zones are independently controlled to achieve a negative temperature gradient, thereby effectively preventing Al from infiltrating the PBN crucible and causing material overflow. With its unique crucible shape, the CL series evaporation source can significantly increase the loading volume, extend the material evaporation time, and greatly reduce the degree of beam change at the moment of opening and closing the shutter. In addition, the bottle-shaped crucible helps to form a constant liquid surface, which can provide excellent uniformity, long-term stable beam intensity and good beam repeatability. According to the amount of material in the crucible, adjust the temperature gradient of the upper and lower temperature zones to optimize the beam uniformity.
