Abstract: Distant galaxies produce ~1, 0.1, and 0.01 gravitationally lensed X-ray sources per square degree with soft X-ray fluxes exceeding 10 -15 , 10 -14 , and 10 -13 ergs s -1 cm -2 , respectively. These sources will be detected serendipitously with the Chandra X-Ray Observatory at a rate of one to three lenses per year of high-resolution imaging. The low detection rate is due to the small area over which the High Resolution Camera and AXAF CCD Imaging Spectrometer instruments have the smaller than 1 5 FWHM resolution necessary to find gravitational lenses produced by galaxies. Deep images of rich clusters at intermediate redshifts should yield one wide separation (Δθ ≳ 5 0) multiply imaged background X-ray source for every ~10, 30, and 300 clusters imaged to the same flux limits.
