Abstract

The James Webb Space Telescope (JWST) will carry on exploration of the early universe with a 6-m exposed primary mirror and cryogenically cooled instruments. The mirror and its instruments will perform extremely deep exposures at near infra-red wavelengths (0.6-30 microns), and will operate for 5-10 years. The contamination effects of foremost concern on JWST are those of scatter due to particulate contamination on the primary mirror, loss of transmission from particulate, molecular and ice contamination, and loss of detector operation due to ice forming during cool-down of the observatory. The effects on JWST science of these contamination sources will be described together with how requirements for cleanliness levels were subsequently established.
