Method for producing a glass tube with a cross section of a noncircular form by reshaping
The invention relates to a method for producing glass tubes with a cross section of a noncircular form by reshaping. This method includes at least providing a glass tube, heating the glass tube, providing at least one reshaping tool, which has a forming body with a forming area for reshaping the heated glass tube, the forming body including at least one open-porous material, setting a gas pressure in the interior of the reshaping tool lower than 90 kPa, so that a negative pressure is produced on the forming area, and reshaping the heated glass tube by applying a compressive force perpendicularly to the longitudinal axis of the glass tube, the compressive force being generated by the reshaping tool and being applied to the outer surface of the glass tube, and the outer surface of the glass tube being fixed by the negative pressure.
OPTICAL FIBER BENDING MECHANISMS
Fiber bending mechanisms vary beam characteristics by deflecting or bending one or more fibers, by urging portions of one or more fibers toward a fiber shaping surface having a selectable curvature, or by selecting a fiber length that is to be urged toward the fiber shaping surface. In some examples, a fiber is secured to a flexible plate to conform to a variable curvature of the flexible plate. In other examples, a variable length of a fiber is pulled or pushed toward a fiber shaping surface, and the length of the fiber or a curvature of the flexible plate provide modification of fiber beam characteristics.
