Zusammenfassung: | The system has a light source (1), an illumination system (2) with an illumination beam path (100), a reflective reticle (5), a reduction objective (71,72) with an imaging beam path (200) and a first beam divider cube (3) in the reduction objective that superimposes the illumination and imaging beam paths. Optical elements (71) are arranged between the beam divider cube and the reflective reticle. Independent claims are also included for the following: a method of manufacturing a micro structured component. |
