Q:

surefire filter

Does anyone know how well a Surefire IR filter on a weaponlight would work with an ATN 350? I don’t know enough about this stuff to understand if the flashlight filter is very specific in its wavelength like the ir led’s?

Thanks Hoot! Judging by some of the groups I have seen posted here mine are pathetic! I hope more illumination from a new light will give me a little more definition on the target.

Damn Mike….

I don’t think I could group that well in daylight! That’s a head shot on most critters out at night.

I got some ambient light from the neighbors deck light the other night and pulled this group at 47 yds with the ATN 350. The illuminator will go this far as well, I am just looking to make more visibility if possible. I know its kind of hard to see, close to 3in ctc. Does anyone have better luck pulling tight groups with one of these scopes?

I bought an IR filter for my LED light and it did absolutely nothing when viewed through my NV scope, and it was a very bright LED.

The LEDs emit a very white and efficient light, with the new tac LEDs putting out up to 200 lumens with just one LED. That’s a lot of light! You can buy them even more powerful, but you just as well use your day scope, which I do, and I can see fine with my light on a dark night. With illuminated crosshairs, you can do quite well out to 100 feet or more on a black night.

It works well – AS LONG as the surefire you using has an incandescent bulb. If it’s an LED then it doesn’t work as well.

Incandescant bulb’s put out light in all kinds of frequency ranges so when you want to filter it into one specific range (ir in this case) it still works quite well.

LED”s are more efficent in that they produce less heat and they also produce less “waste” wavelengths such as invisible IR, so they dont do that well when used with an IR filter.
