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.
