Introducing the carbon fiber reference scale, an exceptional tool characterized by its dimensional stability, lightweight construction, remarkable strength, and high production precision. Crafted from carbon fiber, this scale boasts an extremely low coefficient of thermal expansion, ensuring consistent dimensional accuracy, even in temperatures that vary from the calibration standard.

Attached to the rod are two precisely engineered reference spheres, made from a unique dimensionally stable plastic. Each rod is individually measured using a coordinate measuring machine to ascertain the exact distance between the centers of the spheres with exceptional precision.

This reference scale facilitates quick and easy field testing of your device, allowing you to routinely verify your scanner's performance. It's also ideal for onsite checks post-transportation. When capturing high-accuracy measurements from scan data, you can integrate the reference sphere rod in corresponding scans as an independent control measure. For handheld scanners, it serves as a crucial reference for scans and can assist in improving distance accuracy within the software. Keep in mind that only a limited measuring range across the length of the reference rod will yield reliable results.

**Important Note:**

The reference scale bar offers a straightforward approach to performing basic checks on scan systems, but it cannot substitute the comprehensive measurement processes and geometries conducted by the manufacturer during inspection or calibration. Should any deviations or inconsistencies arise, it's imperative to notify the manufacturer.

Moreover, establishing the sphere center points is a crucial aspect of accurate measurement. Ensure an adequate number of measurement points on the spheres, as the determination of these centers also relies on the sphere detection algorithm employed by the software. Depending on the algorithm used, variations in sphere radii or center points may emerge, particularly in cases of automated sphere detection.
