I have a question for anyone who has and uses an LIF on their NODs.
I understand that LIF's are designed to filter a very specific wavelength of IR to protect NODS from being trashed by high power military targeting lasers. As a side effect of that, they also filter out green visible light around 532nm.
I think this could be useful for hunting with others who have thermal, but not night vision, and need a light to see while walking. But as soon as someone dons a headlamp, anyone with NODs sees a bunch of shadows, flashing, blowback, etc. However, if the person using visible light was using a green light of 532nm, and the NOD wearers were using LIFs, theoretically the visible light wouldn't have an effect on the night vision because the filter would block it.
Is anyone doing this? Also, could someone who owns NODs with LIF and also owns a green LED torch see how well the LIF filters it? I suspect that the LEDs would be creating dirty green light of varying wavelength, and the filtered NODs would still see some of it. But how much? If its a significant reduction, it could still potentially be worth it.
Anyone with experience with this?
