Paper Abstract

Recently Safran Reosc worked and progressed on various thin film technology for:

    Large mirrors with low stress and stable coatings.
    Large lens elements with strong curvature and precise layer specifications.
    Large filters with high spectral response uniformity specifications.
    IR coatings with low stress and excellent resistance to cryogenic environment for NIR to LWIR domains.
    Pixelated coatings.
Results will be presented and discussed on the basis of several examples.
