Re: Source for Light Interference Filters for PVS7b?
Other than second hand sources which can be rather dubious, I do not think that these are usually sold to civilians.
However they also have almost no benefits for civilians at all - they won't protect your scope for any damage that you're likely to encounter away from the battlefield and won't even help with most lasers, not even the IR ones.
I've been told their best use is as a defacto sacrificial lens. This is something I concur with -

interesting. i thought that was their main purpose.
when using an IR laser to aim do you worry about damaging the tube? it seems up close you could burn a spot in pretty quickly with a good IR laser.

Yes, there's a huge misconception about LIFs and their operation. I've put up my public page on them now which demystifies them a lot...
But basically they don't stop pretty much anything that a Gen3 tube is sensitive to... Around 90% of that entire frequency range gets through - IR lasers as well. ( In fact, probably over 98% of the light from IR lasers in the region from 700nm to 950nm goes straight through them. )

Re: Source for Light Interference Filters for PVS7b?
well thats not very helpful.
seems like the ones you tested filtered out greens only?
is there anything out there that keeps an overly bright IR Laser from damamging the tube up when used up close?
