Hi, Anyone know if this thing is totally invisible to the naked eye at night or if it has that teltale red LED glow to it that many illuminators have? |
Unfortunately ALL LED IR illuminators have this faint red glow in the (805-815nm wavelength) Some much more than others such as the Pentagon unit. I am about to publish a IR illuminator shoot-out that compares 4 or 5 of the best IR illuminators out there based on several criteria's, one of which is the red glow or lack thereof. Hope this helps.

That would be great Vic, I have a few illuminators but I loathe them all because of this. Anyone Know if it would be possible to use a LED at a higher freqency that might have less bleedthrough but still be in the spectrum NOD's can still detect. say 850-900nm? How do the units on the PVS-7 or PVS-14 work, they don't seem to glow at all. |
Hi again, indeed I was working with a few designs early on with a new "torch" for Gen 3 looks with several at 910-940nm. Indeed the glow was just about non-existant, but we could not get the intensity we needed out past 100m. Thus far unless one goes with a dedicated laser system, we live with the faints of glow!

Although I will admit to ZERO knowledge of NV or IR illuminators, couldn't the effect of the faint glow be reduced by putting a tube/sleeve around the source of the glow? Or by placing the source of the IR illuminator further back inside the product (in a future model?) Similar to the directional flashlights that can only be seen from directly inline? Or traffic light shields. We use large Folgers Coffee cans to build tubes for spotlights when coyote hunting. It seems to me that it would reduce the ability of others to perceive the glow, if not eliminate the issue altogether? TRG |

It's the nature of the beast. On the M1, the glow is really only visible within a few degrees, directly in front of the optic....and it's really faint. Other IR's are more noticable. As for hunting with it...There's not much possiblity that wild game at night will be spooked. It's not that bright. BTW, has anyone looked into a PEQ-2, to see if it "glowed" 
|
Of course we ALL know Harlikwin and Mfingar are joking a great deal here....To others...NEVER, NEVER, look into an IR laser device. Severe and permanent eye damage WILL occur!  It also applies when pointing an IR laser unit, always know what you target and beyond consist of. Now back to our regular scheduled programming!  |
Sorry...  IR lasers should be treated like live firearms. Same basic rules apply...or you'll end up with a cup full of pencils and a seeing eye dog. |
