EFFUSION CELLS

Unique in design and construction to achieve unparalleled reliability and stability

EFFUSION CELLS are the most vital components in an MBE system. They have considerable impact on the quality of the grown layer, such as surface morphology, thickness and composition uniformity, and film purity. System efficiency is greatly affected by effusion cells, regarding throughput and machine run time. VESCO-NM manufactures different sizes of effusion cells for various sources and purposes from low-temperature to high-temperature applications. Our effusion cells are compatible with different MBE systems and can be installed in various orientations in MBE systems. VESCO-NM effusion cells are also easy to rebuild and to maintain.
