Abstract: A method for manufacturing the monolithic capillary X-ray lens, comprising the steps of Drawing a hollow glass raw-tube into monocapillaries in a heating furnace by a drawing tower; Stacking monocapillaries into a symmetric mould to form a multibundle; Feeding the multibundle into the heating furnace to be heated at uniform speed or variable speed; Drawing the multibundle by a drawing tower at uniform speed and variable speed to form a first integrated lens billet; Cutting the monolithic lens billet into desired shape according to usage to form said first monolithic capillary X-ray lens. A monolithic capillary X-ray lens produced by using said method comprises a plurality of X-ray channels passing from one end through another end, and is a single glass solid formed by melting together the walls themselves of said X-ray channels.
