Abstract
Fabrication procedures employed for producing optical components for the laser interferometer gravitational-wave observatory are described and discussed. Two ultra-pure fused silica substrates, 250 mm diameter and 100 mm thick, were polished to very high surface quality and precision. One side of each substrate is flat with the other side having a very long concave radius of curvature of 6000 m. The performance of the Teflon lap technique in polishing both surfaces will be reviewed.
