The James Webb Space Telescope is now orbiting the Sun and Electrogrip has helped make its mirrors and its infrared optical sensors. Electrogrip’s custom chip processing chambers and fine diamond and laser machining capabilities were used in the Webb Telescope’s construction.
This telescope orbits 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.
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.
