API’s compact and rigid UNIBODY tracker design allows for shaft mounted motors, encoders and laser. The UNIBODY shaft mounted laser innovation minimizes Abbe offset errors, while also housing laser source, optics, camera and major head electronics in the center of the tracker body.

The UNIBODY, and the centering of all heat sources, allows rapid distribution of heat throughout the body during warm-up or drastic ambient temperature variations’ ensuring the tracker body maintains constant heat equilibrium throughout its operation resulting in shorter warm-up time and superior measurement stability.

The rigid UNIBODY instrument casting offers innovative “air-over cooling” minimizing thermal effects, providing increased temperature stability, faster start-up times and further reducing instrument error enhancing overall measuring performance. Competitive trackers with side-mounted lasers create unbalanced heat sources requiring complex and lengthy warm-up routines involving extended thermal stabilization periods before accurate measurements can be performed.
