Paper Abstract
James Webb Space Telescope (JWST) Optical Telescope Element (OTE) mirror coating program has been completed.
The science goals of the JWST mission require a uniform, low stress, durable optical coating with high reflectivity over
the JWST spectral region. The coating has to be environmentally stable, radiation resistant and compatible with the
cryogenic operating environment. The large size, 1.52 m point to point, light weight, beryllium primary mirror (PM)
segments and flawless coating process during the flight mirror coating program that consisted coating of 21 flight
mirrors were among many technical challenges. This paper provides an overview of the JWST telescope mirror coating
program. The paper summarizes the coating development program and performance of the flight mirrors.
