Serious question for those, if any here, that have real experience only.  I have an ITT night enforcer pvs-14 pinnacle that is unbelievable in starlight only.  I have a mount to attach it fully enclosed to a scope with enough inserts to accomodate virtually any eyepiece on any scope in existence.  Last weekend I took it out to my hunt club to test it with several scopes I own and was somewhat dissapointed in many of them.  The current generation of thin film auto gated night vision (nv) is especially sensitive to infrared light, which of course is a part of the spectrum that scope manufacturer's could care less about how much of that light thier scope passes since it is not visible to the human eye.  In starlight only, absolutely no artificial or moon illumination, I can clearly watch a wild boar at nearly 300 yards with the nv only.  Attached to a scope, there is so little light passing through, the only scope I own that is BARELY passable at that range is a 8 year old Zeiss VM/V 3-12x56, second place (and really unusable for my purposes without artificial IR illumination, was my Schmidt and Bender Zenith 3x12x50 and nearly tied my cheap Weaver Classic Extreme 2.5x10x56.  Interestingly, my U.S. Optics sn-3 1.8x10x44 is nearly worthless in starlight only with nv.  I did not get to really test my various Swarovski PH's as the telescoping eyepiece will not really work with my scope mount.  Holding the NV up close to the eyepiece on my Swarovski PH 2.5x10x56 by hand and attempting to look through was pointless due to trying to keep things aligned and not having the scope fully enclosed between the nv and the scope.  Enough light gets in around the objective of the nv like this to have the nv electronics stop down the gain making the view through the scope virtually a black hole, not really that bad, but may as well be.  Long way of getting to the question.  Does anyone know what scopes out there pass a significant portion of infrared light?  I would really like to avoid using an IR laser illuminator due to cost and the pain in the rear it is to get a decent one, I would rather spend that kind of money on a scope that would work, my nv has no problem in starlight only at long range.  And no, an led IR illuminator which is very affordable compared to a laser, is not capable for my purpuses and is out of the question.

Would an infra red filter attached to the scope objective lens not fix the problem?
