Phosphate glasses have special applications, but tra,ditionally never have had both durability and a low glass transition temperature (making them hard to work with). A composition study was used to find a more durable, easily fabricated phosphate glass with a low glass transition temperature. Batching, melting, casting, annealing and fabrication of test parts were performed. Glasses were chara...

Optical glasses doped with a fullerene mixture of C60/C70 were made in our lab. Three peaks, corresponding to C60 , C70 , and a modified fullerene ~possibly its oxide!, respectively, were found in the chromatogram of high performance liquid chromatography ~HPLC! analysis of the 0.1-wt % fullerene doped phosphate glass. Depending on the doping procedure and impurity, weak to strong interacting b...

The energetic χ-criterion is developed to parameterize difference in the origin of high-order optical non-linearity associated with metallic atoms (Cu, Ag, Au) embedded destructively in oxide- and chalcogenide glasses. Within this approach, it is unambiguously proved that covalent-bonded networks of soft semiconductor chalcogenides exemplified by binary As(Ge)-S(Se) glasses differ essentially f...

Aspheric and diffractive surfaces in infrared materials are traditionally fabricated by single point diamond turning, which is a high-cost, low-throughput process, not suitable for low-cost, high-volume applications. Precision molding of chalcogenide glasses is a novel process we developed to allow the efficient fabrication of quality infrared optics in large volumes. In this paper we present t...

In this paper, photonic technologies for the realization of high-capacity optical time-division multiplexed (OTDM) local and metropolitan area networks (LANs and MANs) are addressed including all-optical techniques such as ultra short pulse generation, all-optical clock recovery, optical multiplexing/demultiplexing, and optical packet compression/decompression. Furthermore, the new trends in hi...

Optical endoscopy suffers from several problems which increase the difficulties of a successful intervention. Among these problems are the limited spatial or depth perception, and the fish-eye effect which virtually flattens the geometry of the anatomical structures. Standard virtual endoscopy is inflicted by similar problems. In this paper, we present stereoscopic VIVENDI, an approach for the ...

Abstract Windshield glasses of Maruti Alto 800 (A800), Hyundai i20 (H20), and Suzuki Eeco (SE) are taken from an automotive repair shop for investigating their physical, optical, mechanical properties to check durability. These amorphous, which is confirmed by X-ray diffraction (XRD). Energy dispersive spectroscopy confirms that the windshield contain SiO 2 , Na O, MgO, CaO, Al O 3 K in variabl...
