Abstract
An optical element has a base body with a surface, an optically effective first layer system of which at least one layer system surface is on the base body and a second optically effective layer system embedded in the base body. The second system terminates in an intersection area with a broad surface of the second system extending along the surface of the base body. The second system has a sequence of optically high and low refraction layers, the high refraction layer consisting predominantly of at least one of TiO,, Ta,O,, Nb,O,, HfO,, ZrO,, or SiO,N,and the low refraction layer consisting predominantly of at least one of SiO,, Al,O,or SiO,N,. The packing density of the layers of the second optically effective layer system is at least 0.95 and the second layer system is recessed in the intersection area at most by 5 &mgr;m.
