The FEMTO3D Atlas combines high-tech science and engineering in 3D measurements. It implements and goes beyond the traditional galvo and resonant scanner-based imaging functions and combines them with a unique fast 3D imaging feature, providing an All-in-one solution. The FEMTO3D Atlas enables its users to scan neuronal, dendritic, or other biological processes in 3D, up to a million times faster than classical scanning methods, at a preserved two-photon resolution.
