Does anyone have an idea how this diode would look?
I would think that the beam/spot should still be visible. A very dark purple i hope.
Thinking that 405nm is only 10nm away so its likely much darker. However would it be completely invisible?
I have a 365nm 3W LED and the illumination color appears to be a very pale violet when shined on a white surface, so I would think that 395nm would be a slightly lighter violet than 405nm. I would also think the beam would be visible with the right enviromental conditions.
