The submenu there enables you to jump to lower-level pages of a chapter. As soon as you select a chapter in the navigation column, this chapter is marked with a red square. This lets you know at all times where you are. At the same time, the actual path is shown in this column. Fraunhofer-Gesellschaft brings you back to our Homepage from every point in the site.
Additional functions are always available in the service menu.
The Contact-button links you to the dialog page where you can give us your opinion, order information materials, or get in touch with us. The English-button lets you switch back and forth at will between the German and English site versions. Annotated links and links in submenus are designated with red triangles. These lead you to pages with related topics. In order to jump back to the top of a longer page, click on the red triangle which points upwards.
