Atomic beams have been used for decades but are power-hungry devices that occupy a tabletop.  We have revolutionized atom beams by generating them directly on-chip integrated together with their sources. Key to this process is the innovative use of lithographically defined and etched miniature collimators that result in a low power, compact module. Miniaturization achieves tight control over alignment tolerances and temperature variations to realize extreme accuracy and robustness.  Our beam sources have been lab tested continuously for more than 4000 hours without experiencing clogs.  We also optimize die space on the wafer, eliminating "dead zones" near the collimator frequently encountered in hand-assembled systems. Our patented* design uses both etched micro-channels and carefully constructed gaps designed by Monte-Carlo atomic simulations to customize the output distribution to your needs.
