摘要： The refractive index distribution in refractive index distribution lenses may be adjusted to better approach an ideal by heating the refractive index distribution lens. When the refractive index distribution lens was created by diffusion of refractive index changing ions into a body, further heating in an environment in which no additional ions can diffuse into the body causes further migration of ions within the body so that its refractive index distribution approaches an ideal.

摘要： A process for producing a transparent glass product having a refractive index gradient by the molecular stuffing method is described. A thallium compound is used as a dopant and, after a concentration gradient of the thallium dopant is formed, the porous glass product is heated up to the temperature region of 350.degree. to 550.degree. C. at a temperature-rising rate of 25.degree. to 150.degree. C./hour in a reducing gas atmosphere and then heat treated above 550.degree. C. in an inert gas atmosphere to collapse micropores in the porous glass product, thereby obtaining a glass product having a refractive index gradient which is transparent and free of light-scattering and coloration. The glass product is suitable as materials (preforms) for optical fibers or materials for rod-shaped lenses, particularly rod-shaped microlenses for microlens arrays and microlenses for coupling an optical fiber and a light source.

摘要： A method of producing a gradient-index lens includes a first step in which a glass body is immersed into a molten salt containing ions which are able to provide a refractive index higher than that of ions constituting the glass body, in order to perform ion diffusion into the glass body. Thereafter, in a second step the glass body obtained from the first step is immersed into a molten salt containing ions which provide a refractive index lower than that of the ions of the molten salt used in the first step. In this way there is formed a predetermined refractive index distribution in the glass body.

摘要： Refractive index distribution lenses may be made by forming refractive index distribution patterns in surfaces of two substrates. The patterns in the two substrates are made to be matching. Then, these surfaces of the two substrates are placed together with the patterns in the substrates coinciding. If the refractive index distribution patterns in the surfaces form semicylindrical lenses with parallel axes, the substrates may be put together so that the axes of the lenses in one substrate coincide with corresponding axes of semicylindrical lenses in the other substrate to form a rod lens array. If the refractive index distribution patterns in the two substrates are constant in directions parallel to the surfaces of these substrates but vary in the direction perpendicular to the surfaces, the surfaces of these substrates may be put together to form a slab lens.

摘要： A uniform refractive index-type glass is prepared by ion exchange in which a glass containing ions of a first type is immersed in a molten salt containing ions of a second type, the ions in the molten salt having a higher refractive index than the ions in the glass. The glass is removed from the molten salt at a predetermined point and before the saturation point or equilibrium and the ion distribution becomes uniform throughout the glass. The concentration of first and second ions is not uniform from the center of the glass to its outer surface. The glass is next heated to make the concentrations of the first and second ions substantially uniform throughout the glass from the center to the outer surface. Optionally, this glass is then immersed in a molten salt containing a third type of ion having a lower refractive index than the second ion for exchange with part of the ions in the second type. A gradient refractive index-type glass in which the concentration of the second type of ions decreases parabolically from the center of the glass to the outer surface while the concentration of the third type of ions increases parabolically from the center of the glass to the outer surface.
