Paper Abstract

This paper describes the design of the surface metrology instrument used for manufacturing the 1.5m segmented telescope mirrors. It discusses challenges associated with the design of the instrument, tracking of segment surface data measured with the instrument and cross calibration of the instruments for use at multiple manufacturing sites. The instruments were evaluated for repeatability and reproducibility.
