Bal-tec Integration Spheres are highly accurate laser scanning targets. These spheres are aluminum with a “satin finish“, which means they have an ideal lambertian finish for laser scanning. The ball is hollowed out and a nest is created inside to locate a 1.5 inch (38mm) diameter SMR. The location of the integration sphere can be measured using both, a laser scanner and a laser tracker.

Other integrations include laser scanner and theodolite, laser scanner and portable arm CMM .

The positional accuracy of the nest to the spherical diameter (what we call coincident) is <5 microns

The nest for the 1.5 inside for the 1.5 ball is adjustable and can be tailored to fit individual spheres which might have a size variance.
