I've searched the question, and came across a color chart which shows the typical 400nm-700nm visible surrounded by gray for a few 10s of nm on each side. I'd imagine there is individual variability, and this is what I'm curious about. Can any of you see beyond this spectrum? Is it typical?
I wonder if any visible light can be seen beyond this. Such as in lasers, the 10?0 IR lasers, and the UV lasers in the 300s. Also, florescent blacklight, is the purple which is visible below 400nm or is it just fluorescence/leakage of the filter?
I'd imagine UV lasers would make things visible even if not directly visible due to fluorescence.
When I got LASIK eye surgery years back (193nm I think) the lens looked like it would blink a strange yellow color.
When the semester starts back up, I'll see if I can go to a lab and look through a broad range spectrometer, or a few separate ones if I have to. And if there were some informative and thought provoking replies, I just may post my results :yh:
