Nominal performance and sensitivity of the James Webb Space Telescope: Optical telescope element

The James Webb Space Telescope (JWST) is a large space based astronomical telescope that will operate at cryogenic temperatures, and utilize a segmented primary mirror with active control. To achieve the science goals for JWST, the design requires a large collecting aperture to detect distant faint sources, and a large field of view to accommodate multiple large field of view instruments for efficient surveys. We will address the nominal performance and sensitivity of the design for field dependent wave front error, as well as some of the special optical analysis considerations necessary in a system needing remote, on-orbit alignment.
