Abstract (en)
[origin: WO2019141644A1] The invention relates to a detection device for detecting contamination of an optical element (4), comprising a coupling device (5) having a first coupling element (5a, 6) for coupling light (10) of at least one wavelength of a light source (2) into the optical element (4), and a second coupling element (5b, 7) for coupling the coupled-in light out of the optical element (4), at least one of the coupling elements (6:5a; 7:5b) comprising a hologram, and a detector (8) for detecting the light coupled out.
