Definitions

  • glass containing elongated metal halide particles is thinned to a desired thickness, preferably in the range of 10 to 50 ⁇ using any of the above dicing and thinning techniques. After dicing and thinning to a desired thickness, the glass is subjected to a reducing gas environment as disclosed in U.S. patent nos. 4,479,819 and 4,908,054, to convert all the silver halide particles to elongated metallic silver particles and to thereby render the glass polarizing.
  • metal halide-containing glass is first encased in an appropriate medium to form a composite structure. The medium is preferably any gas permeable material which will not react with the glass.
  • the grinding step can be accomplished in one step, or in a series of steps.
  • an initial grinding step can be done using a 1200 grit grinding wheel in order to reduce the thickness to within a first approximation of the desired thickness, followed by a second grinding step using a 2400 grit grinding wheel to obtain the final desired thickness to within the actual specifications.
