Itek Corporation has been awarded a contract for the manufacture of the primary mirror segments for the W. M. heck Observatory. The primary mirror will contain 36 hexagonally-shaped off-axis aspheres which, when aligned, will form the collecting area of a 10-m-diameter mirror. To ensure integration to the telescope, each segment must be the correct part of the desired parent asphere. During fabrication, careful optical and dimensional metrology must be performed on each segment. This paper outlines the in-process and final metrology plans for each segment.
