Process for depositing a thin transparent layer on the surface of optical elements.

摘要: Process for depositing a thin transparent layer on the surface of optical elements such as made synthetic material in order to protect them against mechanical and chemical deteriorations. The is subjected, vacuum container vapour an organic monomer compound preferably silicon compound. protection obtained from phase by polymerization means radiation electric gas discharge. During polymerization, there are added substances which promote hardening layer, particularly oxygen. Said after beginning obtain good adhesion surface.
