Abstract: A method of manufacturing an optical device having a profile of refractive indices along its optical axis. A desired volume of each of a plurality of types of optical material are dispensed into a mold of known plan area in the form of a frit or a melt and the mold is heated to cause the materials to melt and fuse together to define a contiguous body of optical material having a desired profile. As the optical materials melt, the different types of material separate out so that they are arranged with the most dense material closest to the bottom of the mold and the least dense material closest to the top of the mold. To enhance this effect, the optical materials are layered in the mold in decreasing order of density of the materials from the bottom to the top so that the layers of optical material with the greater densities are closer to the bottom of the mold than the layers of materials with lesser densities.

The resulting mixed glass body is then further stretched to result in a core rod of core diameter at most 0.3 min. After overcladding the core rod with SiO.sub.2, fiber is drawn from the thus produced preform. A thus produced fiber with SiO.

An apparatus particularly adapted to practice the process is also provided.

Abstract: The invention gives a coating with a very high vitrification rate. The resulting surface has physicochemical characteristics which are similar to those of fluoride glass. In order to achieve this result, the material constituting the fluoride glass enamel quickly crosses the temperature range between the melting point and the glossy transition temperature. Moreover, the metallic substrate temperature must be high enough to enable an active physiochemical process at the glass-metal interface which results in a correct "hooking". A "hooking" temperature is higher than one where a physical adhesion occurs, which results from Van der Waals interactions without any formation of chemical bonds at the glass-metal interface. The particular chemical reactivity of molten fluorides, which otherwise results in critical problems of corrosion, is in this case a favorable factor which generally reduces the hooking temperature to a level which is far below the glass melting temperature.

Abstract: A process with minor variations for producing a configuration of glass and/or any similar material such as plastic or epoxy is disclosed. The configuration is basically a honeycomb of pipes of transparent material attached to a transparent plate, such as window glass. The pipes are closed at one end by the plate. The pipes prevent convection movement of a fluid parallel to the plate near its surface, except for very short distances. The unique inventive feature of the process lies in the fact that the honeycomb of pipes are produced simultaneously by a drawing process, during which either a part of a plate, which part is in the form of a grid, is softened, or a grid of new soft material is added to a plate, and the pipes are always attached to the plate both during formation and upon completion of formation.Also disclosed is a special configuration to render the pipes resistant to breakage under thermal stress.
