Optical and Thermal Properties of Mixed Alkali Phosphate Based Glasses

Glassy samples with a composition of 40P2O5&ndash;30V2O5&ndash;(30-x)Li2O&ndash; xK2O, 0<x<30 (mol %) were prepared by the conventional melt quenching technique in two forms of bulk and blown film. X-ray diffraction patterns corroborated the amorphous feature of the samples. Density of samples was investigated by using Archimedes principle. Based on absorption and reflection spectra, indirect a...

Comparison of Semiconducting Behavior and Optical Properties of Oxyfluoride Glasses of SiO2-Al2O3-BaF2 and SiO2-Al2O3-CaF2 Systems

Amorphous semiconductors are materials with a brilliant prospect for a wide range of optical applications like solar cells, optical sensors, optical devices, and memories. The purpose of the present research was to study the semiconducting optical properties of SiO2-Al2O3-CaF2 and SiO2-Al2O3-BaF2 oxyfluoride...

Neutralizing Cylinder Glasses as Test for Malingering.

IT is not easy to outwit a malingerer clainming a reduction of his visual acuity to approximately the same extent in both eyes. Some suspicion is aroused if the examinee reads fluently the first three or four lines of the sight-test and suddenly stops, as if he has decided beforehand lhow far down he will read. A clever malingerer, who has a certain knowledge of the principles underlying our te...

Nano-Structured Optical Glasses

A variety of oxide glasses and glass-ceramics that contain thermally or optically developed nanostructures will be described along with the properties that derive from the nano-phase, or structural rearrangement. The derived properties include photosensitive, photochromic, photoadaptable color, photorefractive (induced refractive index), photo-machinable, and polarizing.

Surface Microroughness of Optical Glasses

The Center for Optics Manufacturing (COM) at the University of Rochester has made significant advances in the fabrication of precision optical components using deterministic microgrinding with rigid, computer-controlled machining centers and high-speed tool spindles. In deterministic microgrinding, the infeed rate of the microgrinding tool across the optical workpiece is optimized and controlle...
