Re: New blue LED from USO
I continue to like green the best - although I only have experience with green and red, never seen a blue lit. Yeah, what is advantage over the two other colors?

Re: New blue LED from USO
Guys this concept was thought of by some scout snipers. This is the feedback we got back from them when they returned from Afghanistan.
- The blue LED gives off less of a signature.
- Do not lose the reticle when looking at different backgrounds.
- Less eye fatigue when glassing for long periods of time.
- Works great with night vision.

Re: New blue LED from USO
In terms of higher frequency blue>green>red so you should be able to keep it at a lower setting then red or green and still see it at low light conditions. In bright light the same applies, it will resist washing out more then the other colors.

The fact that photons of blue light are of higher frequency than green or red and therefore contain more energy per photon is not the determining factor in the perceived visibility of the illumination. X-rays have more energy still and you don't see them at all.
The most important factor is the relative sensitivity of the human eye to light of varying wavelengths. The human eye senses color using three main pigments. Two of these have a peak response very near each other in the green yellow area of the spectrum. Neon green seems to best compromise between these two pigments. This is considered the highest peak in the color response of the eye. The third pigment is significantly separated from the other two in the blue portion of the spectrum. This blue illumination should play nicely for that pigment.
Bottom line. If you want the most optical response for your lumens a yellow/green light is probably best with a blue second best. Red is really the worst you could do as eyes have very low sensitivity to it.
article on light response in the human eye
For what it is worth I find the idea of blue illumination interesting. No one that eye know of has tried it before. That, combined with the fact that it utilizes a different response pigment than the more typical illumination colors intrigues me.

Re: New blue LED from USO
Doesn't blue mean sleepy or relaxed when dealing with color psychology? Maybe that is our boys saying they need a break!
http://www.infoplease.com/spot/colors1.html
Anyhow what I think needs to happen is the ability to change the illumination color to whatever the op wants. At the very least it could lessen the boredom that comes with long periods of glassing.
It is really nice to see US Optics doing whatever it takes to make the war-fighter happy.

Re: New blue LED from USO
I raise my BS Flag. I requested BLUE way back in OEF VII because it is easier on the eyes at night...and told JBW as much back then. I also requested blue on my SN4 that was a replacement for my injured veteran scope but could only pick between green and red. It is not a new idea that just happened. The discussion of blue, red, and green color wave lengths etc has been one of phone conversations between JBW and I some years back(before and after OEF VII). Young punk ass STA Marine's idea...gimme a break
And Happy Belated to all my Marine brothers, and Happy Veteran's Day to the rest of the ones who served!

Can colors be changed in old style rheostats? I ran my green at Rifles Only's night shoot this weekend and wished like heck it was red like my others, but I'd dig trying a blue!

If you also take ideas from non-marines, how about an RGB LED that users can set a color on themselves?
If not technically feasible, how so? Battery life? Not enough room for buttons?

Re: New blue LED from USO
I would send my green lit back for a change to blue too. I love blue light, especially at night or in the dark when red hurts and green is also bright, but not nearly as so as red. I remember seeing that Circle Chevron in my eyes for about two or so minutes after looking through it at night during OEF VII. It was kinda cool, imagining I had a reticle in my eye but only for a minute until it went green then died off

Re: New blue LED from USO
The blue does look good ~ who knows maybe some day technology can figure out how to have multiple colors of reticles that are switchable.

Re: New blue LED from USO
<span style="text-decoration: line-through">Red is probably best. It preserves night vision of the human eye. </span>
That is what I was going to write and express my thoughts to reinforce that view. It has been a while since studying the physics of optics although, A little research yielded the following.
Interesting but beware, the term night vision is used in a different context:
<div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body">
"Night vision also has constraints: your night eye can't see colours or details, or directly ahead, or differentiate objects that don't move.
For night vision in the pilothouse, switch lighting between daytime white and night-time green or turquoise instead of the traditional red. Turquoise may be better for men with red/green deficiency.
Red (630 nm) is an internationally recognized attention colour traditionally favoured for its excellent ability to preserve night vision. However, red erases red lines that indicate hazards or danger on aeronautical and military maps and charts.
Today most pilots and the military have switched to other colours for night vision protection. Green is now the established colour. It is used in the 2004 Daimler-Chrysler 300C. Green is also great for retaining night vision, and it is easier on the eyes.
However, there appears to be a slow transition to blue. The military is using blue over red increasingly. Blue eliminates many colours on maps and charts, changing everything to shades of a bluish-grey. Blue is also a great reading light. It imposes less eye strain than incandescent, especially for ageing eyes. Turquoise (495 nm) appears slightly brighter than blue. Turquoise is an excellent alternative to red for night vision preservation.
Current literature on night vision recommends:
•Blue-green (507 nm) for the fastest dark adaptation recovery
•Deep red (around 700 nm) at very low intensity for maximum detail
•White at low intensity if you need to see colours"</div></div>

Re: New blue LED from USO
It is very unlike me to criticize, but blue illumination is a very bad idea. Very hard for the eye to focus on blue lettering in the dark. Back at home in NY, Nassau University Medical Center on Hempstead Tpke has a very big lit sign on the side of the building in blue; from what I can recall, I think it says 'NUMC'. At night, I kid you not, I can barely read the letters; the blue lighting blurs the shit out of them

That is why airport lights on the ground, which guide pilots to the terminal upon landing, are blue.
It also explains why the sky is blue. Really. Blue scatters in our humid atmosphere and our war fighters are telling USO it has less IR signature. 100-years ago, a Physicist named Rayleigh noticed the same thing.

Re: New blue LED from USO
I was under the impression that blue was actually harder for the eye to focus on because the wavelength falls short in the focusing mechanisms of the eye. This is why eye Dr's advise against blue tinted sunglasses. Personally I couldnt even begin to debate it either way but this was what I was told by someone knowledgable on the subject. My personal pref is for green.

Yeah, the lights are blue, but you don't need to focus on the lights to steer a plane on the ground. Look, if you want to take the pepsi challenge, look at a sign in illuminated dark blue lettering, just like the new USO reticle, and you tell me how easy it is to read compared to other colors. Your example of Rayleigh equation has absolutely nothing to do with this topic. You are trying way too hard searching for scientific evidence to justify your clearly evident worshipping of US Optics.

These last two guys are right. This is not a good thing. Blue light is harder to focus, causes eye fatigue, and in some cases can actually be dangerous.

Again I think it'd be great if the color was user-configurable, using RGB LEDs.

Re: New blue LED from USO
If spec op guys say that blue has less IR signature, and allows them to stay more hidden in the field, then good for them. But I don't understand the mentality of a civilian going out of his way to get this reticle, simply because the "high speed" guys are using it. Whatever guys, knock yourselves out. Use a blurry reticle. Oh, yeah like most of you are gonna spend a lot of time shooting with illumination anyways.

Re: New blue LED from USO
my new uso on order will have the blue color. i will let yall know how it is when i recieve it. i have a trijicon spectrum i have owned for 20 years and it has 4 different colors when hunting and it is last light and the black crosshairs disappear the green is the best hands down by far. better than red yellow orange.
