I've got to wonder if putting a flat filter lens over the scope's objective would make a scope "read" enough differently to the laser that it would be overlooked. Sort of like when you put a clear filter over a camera lens to protect the camera lens.

I had a similar idea myself. A "filter" using plain window glass. A camera type filter, even a clear one, is polished I believe. If so, it would give a similar signature to the polished objective lens I would think. I don't know if the laser would find polished optics behind a regular piece of glass or not. It would be interesting to find out. (although I wouldn't want to find out the hard way that it didn't work)

Also, the effect on sighting through an imperfect piece of glass would reduce the effective range of whatever you were shooting.

I think the laser would go right through the flat glass and find the cuved lenses and report back "SNIPER! FIRE!"
