Abstract
The present disclosure relates to a device for distance measurement for a laser processing system, comprising a collimator lens system, which is set up to collimate an optical measuring beam, a deflection lens system, which defines an optical axis, wherein the deflection lens system comprises at least one transmissive optical element, which is displaceable relative to the optical axis, in order to deflect the collimated optical beam from the optical axis, and a focusing lens system, which is set up to focus the deflected measuring beam onto a workpiece.
