Paper Abstract

The James Webb Space Telescope optical telescope element mirror components, 18 individual primary mirror segment assemblies (PMSA), the secondary mirror (SM), tertiary mirror (TM), and Fine Steering Mirror, have all been fabricated. The performance of the optical telescope (OTE) based on the as-measured optical components is combined with alignment tolerances and the on-orbit alignment process to predict the imaging performance of JWST. The best estimate of the wavefront error, Strehl ratio and Encircled Energy stability is presented.
