The motorized 4-axis high-precision object holder controlled by the 3D joystick makes it easy and convenient to adjust the position of a 3D object with accuracy up to one micrometer. In addition, the digital control allows you to save the object position, focusing and zooming details and to return to them later. Moreover, the movement trajectories can be saved. The focusing drive and optical system aperture are also motorized and digitally controlled. In all, the OctoNus 3DDM can have a 4+1+1 motorized object control system.
