    摘要： This method is directed at a method for making selectively sculptured lithium silicate crystal-containing glass articles. A photonucleable, glass body is selectively exposed to short wave radiation and then heat treated to cause the development of crystals in those areas of the glass body which had been exposed to shortwave radiation. Those crystal-containing areas are then removed by acid etching and the resulting sculptured glass articles are thereafter exposed to short wave radiation and subsequently heat treated to obtain a degree of crystallization.The inventive method further comprises an improvement step of fabricating glass articles that result in crystal-containing glass articles with smaller intermediate dimensions than the desired final dimensions and subjecting the crystal-containing glass articles to an ion exchange process which exchanges potassium ions for sodium and/or lithium ions at a temperature of about at least 500.degree. C. for a time sufficient to cause the crystal-containing glass article to grow to the desired final dimension.

    摘要： A hybrid fiber expanded beam connector and methods for making and using the hybrid fiber expanded beam connector are described herein. Basically, the hybrid fiber expanded beam connector can be used to connect dissimilar fibers such as single mode fibers that have different mode field diameters (MFDs) or different effective areas. In particular, the hybrid fiber expanded beam connector includes a first lensed optical fiber that is optically coupled to a second lensed optical fiber but physically separated from the second lensed optical fiber. The first lensed optical fiber including one type of fiber is capable of expanding a light beam traveling therein and outputting a collimated light beam. The second lensed optical fiber including another type of fiber is capable of receiving the collimated light beam and focusing the received light beam such that the light beam travels from the first lensed optical fiber to the second lensed optical fiber. In a similar manner, the hybrid fiber expanded beam connector can transmit a light beam from the second lensed optical fiber to the first lensed optical fiber.

    摘要： A collimator for use at multiple wavelengths includes an optical fiber and a gradient index lens positioned at a constant distance with respect to an end of the optical fiber. The gradient index lens has a chromatic aberration at a selected pitch less than 0.01 over a selected range of the infrared spectral region.

    摘要： A method for producing lenses includes assembling a plurality of glass rods having a desired length into a single unit and cutting the single unit into multiple slices, each slice having a plurality of individual lenses. The method further includes finishing the slices to a desired thickness and surface finish and extracting the individual lenses from the slices.
