.~.~ Nonoxygen halide glass (e.g., metal halide, etc.)
DEFINITION
Classification: 65/388
Nonoxygen halide glass (e.g., metal halide, etc.):
(under subclass 385) Processes wherein a major component of the optical fiber, waveguide, or preform glass composition is a halide, fluorine, chlorine, bromine, iodine, or astatine
devoid of oxygen.
(1) Note. Halide glass for optical fibers, waveguides, or preforms which contain minuscule or trace amounts of oxygen, wherein the expressed intent is to exclude oxygen, is found in this subclass.
(2) Note. The most commonly occurring nonoxygen halides are metal halides.
