Paper Abstract

Due to the increase of astronomical projects and of their instruments, the request of large optics with higher optical performances does not stop growing. An important step in the manufacture of these optics is the deposition of high-precision optical coatings.
To answer to this request we developed coatings working at different angles of incidence and spectral ranges on large surface:
  • - anti-reflective coatings for large lenses with strong curvatures,

  • - dichroic coatings with sharp transition for large optics.
Main results will be presented on the basis of several examples of realization.
