Status of the optical performance for the James Webb Space Telescope

The flight components for the James Webb Space Telescope optical system are built and the assembly and integration of the telescope and instrument system is in progress. The optical performance for JWST has been updated using the as-built performance of the individual components; updated predictions for alignment as the assembly and integration process has matured; and updated performance predictions for the flight stability contributors: temperature stability driven thermo-elastic deformation and dynamic response stability to flight disturbances. These updates flow from the collective product of several groups on the JWST team.
