The following Pictures showing more then only Red. But please check the two red Beams. One is a 435nm, the other a 650nm. I can't see a difference with naked eye. Even the Photos showing me no difference. Probably my eyes are not able to see it. Can you?

EDIT: Stupid me ! I ment 635 not 435

435nm is blue lol

and if i had to guess i would say the first red is the 650nm and the other one is the "435" (635nm)
and this is me looking at the middle pic.

In the second photo the 635 is on the right. At least I think so. It's much easier to see in real life then in photos.

Ok, thanks. I just saw at the Website from o-like the nm from 650nm Laser is +/- 10nm. If this is the case, it could be a 640nm and this is very close to 635nm.

It is.. cameras are generally more sensitive to longer wavelengths than the human eye is. How the color is rendered depends on the composition of the bayer filter and the software, which depends wildly between camera's. I have a panasonic camera that just renders 660 nm als magenta.

heres 2 photos i took of my 635nm & 660nm handhelds.

looking at beams, its hard to tell them apart they just appear brighter, but the dot is so easy to tell them apart.

G'Day mate. I think the one at the right side is your 637nm.

I can see a very pronounced difference with one of the reds more orange and the other more toward violet end.

But I work with color- so probably more sensitive to it.
