First, we check that geometrical optics is valid for the gw frequency range on which earthbased detectors are sensitive, and that this is also partially true for what concerns the future spacebased. Lentille gravitationnelle et galaxies lointaines deformees. A gravitational lens is a distribution of matter such as a cluster of galaxies between a distant light source and an observer, that is capable of bending the light from the source as the light travels towards the observer. The aqua circle is the light source as it would be seen if there were no lens, while white spots are the multiple images of the source see einstein ring. Lexpression foyer principal image ne sera pas utilisee. A gravitational lens is a distribution of matter between a distant light source and an observer. We compute the increase in the number of detected gw events due to gl. The amplification, ratio of the lensed brightness of an object to its unlensed value, is larger if the line of sight passes very close to the lens.
