From: Cascaded collimator for atomic beams traveling in planar silicon devices
A gallery of tailored atomic beams. From top to bottom are (a) cascaded collimator (theory, experiment), and focusing collimator (theory, experiment), b measured width of the focusing collimator along with Monte–Carlo theory (solid line), and c the two-beam collimator. In c the arrow points to the chip location. In a the experimental images were obtained by subtracting a background image with the laser tuned away from resonance so no atoms were visible. For the data in b the combination of image distortion and pixellation led to a spatial calibration uncertainty of 5% (9%) along the y-axis (x-axis)
