your taking this off subject. this thread is not to discuss who neg repped who. stay on the topic just slightly if need be
Both 589, and 593.5nm are both labeled as yellow.589nm is not yellow. It is more of a golden color. Yellow is 577nm.
515 is blue/violet?I just use logic though. I mean it's not that hard. Under 532 is blue/violet and 532-600 is yellow/green and 600 and above starts getting red.
Are there actually people who can't see 808nm? If so, can you tell me anything about them? Color blind? Elderly? Just regular people?589nm still looks like a gold orange I've owned 589nm personally. But I guess all of our eyes are different. Just like how some can see 808nm while some can't.
Don't know about uv light, but i see a 405 beam very, very easily (400mw looks almost as bright as 100 of green). On the other side of the spectrum, I have a hard time with a 600mw 635 beam.Are there actually people who can't see 808nm? If so, can you tell me anything about them? Color blind? Elderly? Just regular people?
The reason I'm asking is that for the last 4 or 5 months I've been collecting research papers on human ability to see near-infrared, near-uv, x-rays, gamma rays, particle radiation (beta, mesons, cosmic) and anything else that can elicit a visual response (a blow to the head, direct video feed to the brain).
There is a huge variation in human ability to see ultraviolet, strongly correlated to age and total lifetime exposure to uv. For example, most people under 30 can see uv down to 310nm (with some visual acuity) but people older than 50 usually can't.
I've never heard of any such individual variation in the near-ir, especially at such a low wavelength. If you have more info, I would like to know more.
