Glass fibers optical properties

Aggarwal, I.D. and Lu, G. (Eds.) (1991) Fluoride Glass Fiber Optics, Academic Press, Boston. Contains a series of chapters written by leading experts in the field detailing the structure, processing, and properties of fluoride glasses and their application as optical fibers and use in other optical devices. 

Selenium chalcogenide glasses exhibit good infrared transmission properties. These are used as lenses (ZnSe, CdSe) in laser apphcations and have potential applications in fiber optics (qv) and in data storage and retrieval. 

Within the limitations on the physical properties which generally restrict plastics to low precision optics, plastics materials have found wide applications in optical products that range from lights to binders for electroluminescent phosphors to fiber optics and lasers. They represent an easily worked material with a wide range of desirable optical properties in simple to complex shapes. In this review the discussion has been limited to the differences between plastics and optical glass materials and to some of the unique design possibilities that are especially important for plastics. Using the optical arts and the... 

Highly pure lanthanum oxide is used to make optical glass of high refractive index for camera lenses. It also is used to make glass fibers. The oxide also is used to improve thermal and electrical properties of barium and strontium titanates. Other applications are in glass polishes carbon arc electrodes fluorescent type phosphors and as a diluent for nuclear fuels. In such apph-cations, lanthinum oxide is usually combined with other rare earth oxides. 

The mechanical properties of silicate- based glasses have been extensively studied due to their widespread use as containers, reinforcing fibers, and optical fibers. Consequently, there is a wealth of information on the influence of many variables on the mechanical properties of these glasses. We shall concentrate on (a) composition and temperature effects on modulus and strength and (b) an important method of strength enhancement in glass fibers.
