Specification
Our scale bars and scale kits are made using Invar material to provide a thermally stable reference length for laser tracker, scanner, or photogrammetry jobs.
You can use them to establish or verify scale. Some customers use them as a stable reference artifact which they measure before, during, and after a job - just to gain confidence that nothing has gone wrong during the "shoot". Our kits allow you to construct custom lengths. Be sure to look at our Low Thermal Expansion Scale Bar (1.5LTE-1000MM) which employs a simple mechanism for even greater thermal stability.
