The James Webb Space Telescope is due to orbit the Sun,

further from Earth than the Moon.

Electrogrip's diamond and laser machining had already been developed to process

electrostatic chucks in the hardest materials to micron- and nanometer- level precision.

This capability was used by NASA for the JWST.

Machining mirror segments at Electrogrip

Electrogrip's machining methods were found by NASA to exhibit almost

unmeasurable edge distortion on the precision optical mirror segments

needed for JWST testing.

Electrogrip generated the rough meniscus shape from a large Zerodur® blank,

then applied laser fiducial marks, and segmented the polished meniscus

into hexagonal shapes.
