Abstract

The invention pertains to measuring, adjusting and/or controlling a distance between a machining head, particularly a laser machining head, and a workpiece, comprising a measurement light source, a beam splitter that splits the light of the measurement light source into a measurement light beam and a reference light beam, a reference arm, through which the reference light beam is guided, an optical system for coupling the measurement light beam into a processing beam path featuring a focusing lens, an optical device for superimposing the measurement light beam, and a measurement and evaluation unit.
