Time durability and environmental stability of silver-coated glass mirrors improve if silver layer is protected by a transparent thin film coating. The choice of the protecting layer material and of the methods for mirror manufacturing influences the mirror optical and mechanical properties. This work reports on a systematic study of silver mirrors overcoated by silicon oxide, nitride and oxy-nitrides. Variable angle spectroscopic ellipsometry was implemented to get an insight on metal-dielectric interface of the coatings. The results have been analyzed considering the coating deposition conditions and physical-chemical properties of the dielectric materials used as protective layers. © 2018 COPYRIGHT SPIE.
