METHOD FOR THE PRODUCTION OF OPTICAL LAYERS HAVING UNIFORM LAYER THICKNESS

摘要

According to the invention, optical layers with uniform layer thickness are produced by spraying on a substrate a coating composition produced according to the sol-gel process and containing a high boiling solvent, which is based on inorganic or organically modified components using a flat spray facility and subjecting it to thermal treatment. The wet film thickness during sprayi ng of the coating composition on the substrate is preferably regulated in such a way that it is at least eight times bigger than the desired dry film thickne ss.
