Finished Corrector

August 15, 2018 by

The completed 6-lens corrector, weighing in at 8,900 pounds, will deliver a huge 8-square degree field-of-view. That’s a sixteen times larger field-of-view than the previous optics. The six hexapods bolted to the skirt will actively position the corrector to microns accuracy.
