4.25" X 2" X 0.06" thick. Master box is marked "GOLD/CR". Not sure what the original application was but it acts almost like a beamsplitter. One side reflects about 75% while transmitting about 25%. The other side transmits about the same but with very little reflection.. Looks like a fun piece to experiment with.
One of our customers was able to do an analysis of its composition. Here's his findings: "180 Angstroms of gold deposited over 30 angstroms of chromium on glass containing tin oxide" |
