Linear organic evaporator

The VON ARDENNE Linear Organic Evaporator is a component that thermally evaporates organic material in a closed crucible. The vapor is distributed through a heated pipe in the direction across the substrate and released to the substrate through a linear nozzle array.

All parts that are in contact with the organic vapor – primarily crucible and nozzle pipe – are made of ceramics that are completely inert to the OLED materials. Crucible and nozzle pipe are heated to a temperature above the condensation point of the organic materials.

The surfaces facing the substrate are shielded by directly cooled copper parts to minimize the thermal load on the OLED substrate. The system enables the inert loading and unloading of air-sensitive evaporation materials.
