Abstract:
A process for producing a tapered monocapillary optic having a paraboloidal figure for focusing radiation comprising the steps of:providing an etchant bath;providing a wire to be etched by the etchant bath;placing the wire in the etchant bath to a preselected depth for etching;withdrawing the wire from the preselected depth at a controlled rate to form a differential etch to form a tapered wire with a desired paraboloidal figure of the tapered monocapillary optic;coating the tapered wire with a coating reflective of the radiation to be focused by the monocapillary optic to produce a coated wire; and,removing the tapered wire from the reflective coating to leave only a reflective bore having the desired paraboloidal figure for focusing radiation.
