| These were made by Perkin Elmer and are either Zerodour or CerVit (we can't tell the difference). Looks like these were first made as a full 5" diameter flat and then cut to size for a specific purpose. Long dimension is 5" and short dimension is 3-1/2" and is 1" thick. These are beautiful pieces of glass and we only have a limited supply. Polished on one side to 1/20th wave. Reverse side is ground, not polished, with serial number engraved. Unused. Closing out at half our original low price |
