We present a method based on wave front engineering for rendering a Bessel Beam (BB) lattice with one single, flat, and lightweight optical element. According to this design, we fabricated and characterized a Silicon Nitride (SiNx) element using Meta-Surface (MS) technology encoding all the operations required to generate the designed BB lattice. Finally, we demonstrated its application in microscopy by integrating it along the excitation path of a light-sheet microscope (LSM) and recording neuronal activity from the zebrafish larva brain.

Abstract
We present a method based on wave front engineering for rendering a Bessel Beam (BB) lattice with one single, flat, and lightweight optical element. According to this design, we fabricated and characterized a Silicon Nitride (SiNx) element using Meta-Surface (MS) technology encoding all the operations required to generate the designed BB lattice. Finally, we demonstrated its application in microscopy by integrating it along the excitation path of a light-sheet microscope (LSM) and recording neuronal activity from the zebrafish larva brain.
