Abstract: The invention relates firstly to a method for determining a mechanical deviation on a displacement path of an optical zoom lens, in particular on a displacement path of an optical zoom lens of a microscope. The optical zoom lens is arranged in a beam path between an object to be recorded and an electronic image sensor.

Abstract: In a method for additive manufacturing of a workpiece, a data set defines the workpiece in multiple layers. A first energy beam is moved relative to a manufacturing platform along first trajectories to produce, in temporally successive steps, a stack of workpiece layers.
