in a method of connecting a multiplicity of optical elements to a basic body , in particular for producing a faceted mirror , for example for beam mixing and field imaging for an euv lighting system , the individual optical elements are positioned on the basic body and subsequently connected to one another by an galvanoplastic process . alternatively , the multiplicity of optical elements are aligned on an auxiliary structure and the optical elements are subsequently made to grow up galvanoplastically on their rear sides , forming a supporting structure as the basic body .
