PLASTIC OPTICAL FIBRES AND METHOD FOR THEIR PREPARATION |
摘要 |
Optical fibres of methyl methacrylate-styrene copolymer are produced by forming a sheath in the form of a solid cylinder having at least one cylindrical recess and at least one cylindrical rod constituting the core of the fibres, the rod having a smaller diameter than the recess, introduction of the cylindrical rod into the recess, placing the gap defined between the rod and the cylinder under a vacuum, raising the temperature in order to soften the cylinder and engage it with the rod under the effect of the vacuum and drawing the thus obtained preform. |
