An optical element structured in accordance with the invention comprises a
substrate with at least two zones with different optical functions. The
coating systems in the two zones can in each case be subdivided into a
zone-specific internal partial coating system and a complementary partial
coating system that is common to all the zones, where the complementary
partial coating system comprises at least one layer and in the zones in
which the internal partial coating systems comprises at least one layer
said coating system is arranged between the substrate and the
complementary partial coating system.
