Abstract
Accurate assembly characterization is critical to the proper assembly and alignment of optical systems, such as the Hobby-Eberly Telescope wide field corrector (WFC). The WFC is comprised of four mirrors built into a steel structural housing, with a maximum weight of 1,800 pounds; the alignment of the mirrors depends on accurate knowledge of the structural dimensions. To examine the structure of the WFC system and find out the decentration, we used the FaroArm portable coordinate measuring machine combined with SpatialAnalyzer software. The next step was to decide how to adjust the system to make it well aligned based on the measurements. We found concentricity of the major portions of the assembly that was less than 0.5 mm.
