Classification: CPC G  F | IPC F  G

Claim 0:
1. A laser tracker calibration system comprising:
an artifact;
a first kinematic mount selectively coupled to said artifact at a first location;
a second kinematic mount selectively coupled to said artifact at a second location,
wherein said first and second kinematic mounts are coupled to a rigid support structure so as to hold said artifact relative to a laser tracker during calibration of the laser tracker; and
a positioner rotatably coupled to said rigid support structure,
wherein said first kinematic mount prevents said artifact from rotating about a longitudinal axis of said artifact, and
wherein said second kinematic mount prevents said artifact from rotating about said first kinematic mount and allows for differential thermal expansion and contraction of said rigid support structure relative to said artifact without stretching, compressing, twisting, and/or bending said artifact.
