Arrowhead's FF 1.0 Filter

[SConner]

I reached out to Arrowhead and got a very nice reply from one of their sales reps. If someone wants more information or his reply, just PM me and I'll send it on to you. The green coloration is just a trick of the way it was photographed. He did assure me that it has more of the mirror coated look that we're familiar with for narrow band pass filters and it is comprised of multiple layers of glass.
