Maybe it is laminated, but I can't see that it is. The element simply looks like a single piece of tinted glass. I taped it into the ring, mounted it and, looking 90 degrees from the sun, twisted it, twice using both sides. It appeared to work the same either way.

So I carefully glued it in and it works fine. No need to spend another $40-$60 for a new one.
