Abstract:
A process for producing an array of tapered capillary optics for focusing radiation comprising the steps of:providing an etchant bath; providing a uniform array of wires to be etched; placing the uniform array of wires into the etchant bath to a preselected depth for etching; withdrawing the uniform array of wires from the preselected depth at a controlled rate to form a differential etch to form a uniform array of tapered wires with substantially identical desired tapers having a desired taper profile of the tapered array of capillary optics; coating the uniform array of wires to produce a coated uniform array of wires with each wire having a coating reflective of the radiation to be focused by the array of capillary optics; bundling the uniform array of wires to provide a bundled coated uniform array of wires; and, removing the uniform array of tapered wires from the coated uniform bundled array of wires to leave only an array of substantially uniform coated bores having the substantially identical desired tapers for focussing radiation.
