Hey guys not to threadjack but my question is somewhat related. Max visible spectrum is something like 556nm but I read a post from Greenlander informing that that is the max visible spectrum for daylight while darkness has a different max visible spectrum. Does anyone know what the max visible spectrum in darkness is?
Here's a question about the nearly invisible spectrum, but in the other direction, is 405nm the shortest wavelength we can currently obtain reasonably priced laser diodes with a few hundred mw or more of power output? Are there any diodes in the 300-400nm range? I can't seem to find any, light emitting diodes yes, laser diodes no.
