Our objective is to build equipment and devices capable of manufacturing mono- and policapilares lenses from glass to focus the rays x. Um motivating factor is the experience of manufacturing optical fiber Luxtec closely related to the state of the art for the manufacture of focusers for RX. These lenses will be manufactured from glass capillary tubes that are heated in a furnace with controlled atmosphere and in a properly tensioned fitted. As pulling tower, lenses will be "stretched" in a elliptical shape using the model retention pasta. Este model states that the mass of glass entering the hot zone of the furnace is equal to mass exits. Important processes must be addressed: 1- Preparation system of the glass tube, the objective of this phase of manufacturing, is dimensionally fit glass tubes commercially available. Our raw materials are glass tubes with appropriate physicochemical properties specified from the premises of and optical function of the synchrotron line where design is used. Will require a glass melting system with traction belt to achieve the appropriate diameter for the next manufacturing step (manufacture of the elliptical lens) system, specific treatment of the inner surface annealing system to eliminate the voltage generated due to drift, cleaning ultrasound, etc. 2- Modeling system, the glass cylinders prepared by the system 1 will again be subjected to heat and traction. By monitoring and feedback of certain parameters, varying the speeds of entry and exit of the pipe in the kiln, "we deform" according to the desired shape (elliptic, hyperbolic, parabolic, etc.) .Once the process ended, the lens will be attached to the tube and should have relieved their tensions and separated mechanically through the original tube diamond tools. The challenge of this work is the elimination of surface roughness, one of the shortcomings of this system. 3- Optical characterization system to streamline the process of optical characterization and calibration of the system during development, a system will be mounted to the internal filling of the capillaries produced with polymerizable materials having refractive indices higher than the material used in its manufacture.
