Hi, Ken,

 

SUPPOSEDLY the human eye can see up to 700nm, and women can see longer wavelengths than men.  That said, I agree with the others who responded - I haven't met anyone who can see it.  A camera, however, or confocal can detect far red.

 

Good luck,

 

George

Hi,

we're considering buying a Y5 filter cube from Leica to see the far-red Alexas, DRAQ5 etc. but then someone mentioned to me that many (most?) people are unable to see far-red light. Does anyone know if this is true, or have experience with this (or a similar) filter cube? It has a BP 700/75 suppression filter.
