Didn’t Scotty come up with this already?
His was aluminum.................
What’s The Deal With Transparent Aluminum?
"Despite clearly not being a metal — and not a glass either; glasses are amorphous solids, while ceramics are crystalline — AlON and the other transparent ceramics that have been developed since have some amazing properties. AlON, marketed as the uncreatively named ALON by its manufacturer, Surmet Corporation, is produced by sintering. Powdered ingredients are poured into a mold, compacted under tremendous pressure, and cooked at high temperatures for days. The resulting translucent material is ground and polished to transparency before use.
Aside from being optically clear, ALON is also immensely tough. Tests show that a laminated pane of ALON 1.6″ thick can stop a 50 caliber rifle round, something even 3.7″ of traditional “bullet-proof” glass can’t do. ALON also has better optical properties than regular glass in the infrared wavelengths; where most glasses absorbs IR, ALON is essentially transparent to it. That makes ALON a great choice for the windows on heat seeking missiles and other IR applications."
Except for the IR transparent part, a good thing for those "See Through" parts of your Jet Fighter cockpit! I imagine that they can sandwich in something to remove the eye damaging IR wavelengths.
