摘要：A clad pipe () is produced by heating PVDF to 180° C., and then this PVDF beingextruded from a melt-extrusion device. The clad pipe () has a square cross-section whosesides L are 20 mm length, and in a center thereof, there is a square hole. In the square

hole, a core () mainly includes PMMA is formed. Accordingly, a preform () having a clad ()of PVDF and the core () of PMMA is obtained. The preform () is heat-soften-drawn at 210°C. A drawing ratio is 1600. Finally, an optical member () having a 0.5 mm square cross-section is obtained.
