Scale Bars for Laser Trackers

Our scale bars are made of Invar material to provide a thermally stable reference length for use during laser tracker or scanner jobs. Use them to establish or verify system scale. Some customers shoot our scale bars before, during,and after a job to gain confidence that the instrument has not shifted during the “shoot”. Our Low Thermal Expansion scale bar employs a simple mechanism to reduce thermal expansion even further. Use our scale bars with your laser tracker (or laser radar) to verify system accuracy and stability during a measurement job. Many of our customers shoot a length reference bar at the beginning, middle, and end of a job to gain confidence that nothing moved or changed during the job.
