    I saw a polarizing lens with a rubber attachment to a scope on a guys rifle a while ago. I actualy played with it and noticed that it was great for combating glare and some window tints.
    I tried the search button and no luck.

    Does anybody know where I can get one of these?

    you might be able to get a polarized lens from a camera store that would fit your scope but you might have to take your rifle with you to make sure the threads are the same.

    +1 Hoya filters work nicely.

    Civie's are not restricted to the normal supply chain. Just because it says LE or Mil only does not make it the best. Nor does it say you can't come up with something cheaper and better. Anything plug an play you pay threw the nose for it, most of the time. Camera shops can supply every lens you need/want, you just have to adapt it. Which is no big deal.

    Depending on your objective size, take your scope to a good camera shop and see what they have for you. I'm thinking about trying this with the NF's and just walking in with the sunshade. This way it doesn't need any explanation, you just want a polarizer for a "lab camera" or something.

    You want a circular polarizing filter for the eyepiece not the objective.

    What effect does it have if you put it on the nose of the scope instead of the eyepiece?

    The rotation of the filter will cause an image shift before it reaches the reticle, therefore shifting the POI.

    The sunglasses are fine, the the filter can be rotated to kill the glare, the glasses cannot.

    While it does work, there are numerous problems shooting through glass, so unless you are an agency type and have no other choice but to take that shot, it's really hardly worth having.

    Polarizing lenses and shooting don't go together IMHO. Look at any sport where athletes use sunglasses: you don't see any polarizing lenses. There's a a reason for that.

    Well maybe fishermen use polarizing lenses.

    <div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body">The Problem:
    Glare and reflections from glass surfaces such as windows and windshields can seriously degrade your view.
    In MOUT operations, surface glare can prevent the identification and targeting of snipers. In hostage situations, glare can make it impossible to differentiate between hostage and hostage taker.

    The Solution:
    A correctly oriented polarizing filter will block glare. This is so because most of the light rays that cause reflected glare are polarized, that is, they vibrate in one plane. A polarizing filter acts like a screen.
    When rotated so that it is aligned across a polarized light ray's axis of vibration, it blocks that ray, giving you a clearer view through the surface behind.
    A filter mounted on the front of a scope can change your point of impact by slightly shifting the image you see.
    Our patented Weapon Sight Polarizer is a rugged, field-practical unit that mounts a rotating polarizing filter at the rear of the scope, where it will not affect point of impact.
    The filter easily flips out of the way when it is not needed.</div></div>

    I have a lightly used Tenebraex Weapon Sight Polarizer that fits a S&B 8541 that I could be talked out of if someone needs one. It cost me $100 would let it go for $105 shipped USPS Priority Mail in the CONUS

    My prescription Oakley's are polarized, I got them that way for fishing the flats in the Florida Keys. Since I wear them everyday and have for several years I've noticed a few benefits of polarized glass vs non-polarized. Polarization helps in two ways: first it cuts glare and second it provides better contrast. I find it much easier to perceive relative distances and to focus in on the details of brightly colored objects in full sun with my polarized glasses on. I am not sure why they are not more popular in shooting, I have to wear glasses when I shoot and I always wear my polarized sunglasses (except indoor ranges). To me the difference between my regular glasses and my polarized glasses is night and day when trying to focus on the details of a small target at range. The POI shift mentioned above would scare me away from a filter, but you can buy a pair of decent polarized glasses less than you can the filter.

    Several years ago Lanny Basham and Lones Wigger had made and distributed a variable polarizing filter to be used with the rear sight on a smallbore rifle. Lones still uses his sometimes outdoors.

    I have a blueblocker lens I sometimes use in my Knoblocks.

    Under most conditions, where there is an excess of available light reflected off your target, limiting spurious light goes a long way to increasing image clarity, regardless of the method used to limit it.

    If you are not shooting through glass then it's just an expensive "look what I have" kind of thing.

    If you are shooting through glass they can be a very good tool. I have handled them and know of at least one tactical shooting problem that they would have helped with. I am in the process of trying to get a couple for our team.

    I can tell you that when I am working a checkpoint and need to see into vehicles through glass, polarized glasses are the trick.

    Not really as it depends on the way the light is reflecting ie the way the tint and or glass is laid and laid in (angle, grind etc). The tenebrex eye piece can be rotated to compensate for these differences! It is very effective. If I could find a polarizing camera filter lens that would fit the eye piece I would go for it but so far I haven't found any.

    I wore polarizing glasses in Iraq to help with the issue but one of these with optics works even better (I has handled one before and like the idea!).
    I understand that shooting through glass increases the chance of something going wrong but every multiplier is just that, a multiplier for the tool bag.

    The sample I looked at during Sniperweek had fresh blood on it. </div></div>

    Must not have been a Tenebraex. I will have to get a photo of the one I have. BTW I believe LEO pricing is around $75 ea. (or was a couple of years ago).

    <div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: LoneWolfUSMC</div><div class="ubbcode-body">This was most definitely a Tenebraex as marked.

    That price is consistent with what I have see, although I have been unable to contact them about actually acquiring a few for my department. </div></div>

    I'm having the same issue!

    A few pics of the Tenebraex weapon sight polarizer.

    The ring shown in the second photo rotates to adjust the polaization.

    I have one that fits my NF that I don't use a whole lot, or ever.

    However, I have to say that I never noticed a difference in zero when I did use it.

    MtGoat, have you?

    Here are some pics. Same as his:

    DSC02639.jpg


    DSC02640.jpg


    I got it from another DM downrange. I replaced him on a route overwatch position. Like I said, haven't used it much since.

    Tenebrex has not been good at responding to my emails at all!
    I almost wonder if they are still in business or don't care about .mil email ala military account emails?
