  • : Overview of Available MÖLLER-WEDEL-OPTICAL

    Alignment Systems are precision instruments for the alignment of objects on a reference line, which is defined by the line of sight of the system. A special feature of alignment systems is that the direction of the optical axis is conserved during focusing. This property makes them especially useful for the alignment of bore holes, bearings, optical set-ups or for the alignment of guides, axes ...
