I Most people can't really see above 700nm... yours is 808nm.
You simply can check this yourself if you own a really death IR diode and a nightvision. The diode will still emit some visible red light but absolutely no IR. Or do the opposite. Take a LPC 815 and check with your IR filtered military nightvision the amount of IR. You will see even a red 650nm lasediode produces a little bit of infrared.
Ok. This is not an absolute prove because some death IR laserdiodes still produce some IR light. They just wend LED. But some will have no IR at all while still emiting some visible red. It´s due to the nature you can´t produce an absolutely clean cristal that just emits in one single wavelenght.
Also. An IR laserdiode that wend LED will still produce the same amount of visible light like before it wend LED. So if you could see IR light you should see a difference, but you wont see a difference. Only with a high quality IR filtered nightvision you will notice the the difference. Or of course with an LPM.
And what´s about o-like. I also ordered a few items from them. Also tied to chat with Susie, but got just very short answers or no answers at all. Lets´s see how long it will take to arrive and how good the items are. I will review them here as soon as i get them.
1. Minor detail - You misquoted me - in a sloppy manner and doesn't change much, but it's annoying. So that's strike 1.
2. If you look at my quote I don't say that IR is visible do I? what I did say was:
Most people can't really see above 700nm... yours is 808nm.
Sam's Laser FAQ - Items of Interest
People can see roughly between 390nm and 750nm. Which is near IR. Strike 2.
3. You went completely OT without actually adding any useful to the conversation. Strike 3.
Three strikes - you get a neg rep.
Edit: You neg repped me on the wrong post. Pretty sure there are no scientific articles about o-like location
