Nope, why would I be trolling? It's the same material as the focus lens. They are available for some FLIR models, but they go for about $350-$500.
It isn't aspherical, it's just flat. But a zero-meniscus lens with a curved surface would hold up better to BBs :P
Some polymers transparent to far-IR work as well.
