摘要： The present invention relates to a method of making a rectangular bar have a gradient composition. In optical or ophthalmic applications, the gradient of composition ensures formation of a corresponding gradient of optical property, such as refractive index or optical density. The glass material is manufactured using a device containing several reservoirs, all designed to contain glass in the fluid state. According to the invention, the composition of the glass varies from one reservoir to the other so that the refractive indices, for example, of the three compositions are different, with an incremental progression. The fluid glass is deposited one composition on top of the next and then heated, creating a certain degree of interdiffusion between the layers. The glass is then heat-treated to create the desired property profile.

摘要： The material is in a fluid state at a predetermined temperature above the ambient temperature. According to the invention: a) at least two different compositions of this material in the fluid state are prepared; b) simultaneously and concentrically both the core of the rod with the aid of one of the compositions and a sheath enveloping this core with the aid of another composition are cast; and c) the casting is then taken to a temperature at which it solidifies to constitute the rod. Advantageously, the section of the casting is made to grow by its passing through a cylindrical mold shaped to define the final section of the rod. Application to the manufacture of a glass rod presenting a cross-sectional refractive index gradient.

摘要： A double crucible fiber fabrication system employing a rod to control flow of the core material to produce a core of desired diameter. The rod fits closely within the inner crucible and moves at a speed necessary to produce a core material flow rate which will produce a desired core diameter. Control of the rod speed produces good control of core diameter for a wide variety of different core materials. It is also possible to control the rod speed in order to compensate for capillary effects and leakage of core material. Furthermore, control of the rod speed allows fabrication of a fiber having a core diameter which varies as desired throughout a single fiber.
