The novel features of the FEMTO3D Atlas are the electrically tunable acousto-optic deflectors (AODs) which are responsible for the X, Y, and Z focusing (acousto-optic or AO technology). These deflectors do not contain scanning mirrors or any other slowly moving mechanical components, so the positioning of the focal spot is fast, flexible, stable and independent of the travelling distance. This positioning freedom results an extremely high scanning speed, up to 30 kHz at any 3D location in a cubic millimeter volume under the objective.
