[ARCHIVED THREAD] - Night Vision Protection from IR Devices?

Posted: 8/28/2018 3:48:40 PM EDT

I tried looking through the NVG forum but I can't find the answer. Anyone know what the lenses that protect NVGs from IR exposure are called and where I can grab a pair.

I assume you are wanting military light interference filters. I see them occasionally here on the EE and other night vision forums.

Ive been looking into this as well. Do the If lenses that fit the PVS14 also fit the PVS7 or is it a different part number?

According to amazon, it fits both. No idea about the legitimacy of these. The price ranges very wildly. Own the night has em for $140, Amazon for $50 and I've seen em here for as low as $25-$30.

Given that you probably wouldn't notice a difference there could be many that mimic the LIF operation by just doing that which can be directly observed. If the "clones" wouldn't do what they are supposed to you'd only notice that when you're in a very odd situation where it would be beneficial to have the filter on and working.

Thank you for the input. Picked up one for $30 shipped just now. Will know next week if ti fits my PVS7 like it is advertised to do.

LIF's don't provide the protection you think, I think, but as you haven't said what you need protection from IR devices for, I can't be certain.

Generally, though, putting in a bandpass filter on NV will only reduce it's performance... Even a LIF will cut performance about 20% - maybe more on newer tubes.

They will fit a PVS-7 B/D model though.
