摘要:
An optical arrangement for immersion lithography, having at least one component (1) to which a hydrophobic coating (6, 7) is applied, the hydrophobic coating (6, 7) being exposed to UV radiation during operation of a projection lens, and the at least one component (1) being wetted at least in part by an immersion fluid during operation of the projection lens. The hydrophobic coating (6, 7) includes at least one UV-resistant layer (6) that absorbs and/or reflects UV radiation at a wavelength of less than 260 nm.

摘要:
In order to improve a coupling unit that is mountable on the rear end of a vehicle body and comprises a carrier unit which, for its part, is mountable on the vehicle body hidden by a bumper unit and which comprises a coupling arm held on the carrier unit for coupling a trailer or a rear load carrier, in such a way that detection of the mechanical loads on the coupling unit is possible in a simple way, it is proposed that there be provided at least one force detecting region on sections of the coupling unit that are mechanically loaded by the coupled trailer or the coupled rear load carrier, in which a sensor associated with this force detecting region detects the mechanical load acting on this force detecting region by means of the magneto-elastic effect.
