After reading a similar post over at APUG, I began thinking about darkroom work with night vision equipment.
I have been using an infrared monocle for some time in the darkroom and while I was assisting someone in the darkroom get acclimated to it recently, I noticed that there is a small green glow of light about the rear eye piece. On the same subject, my infrared light source on the monocle emits a small red glow as it produces the infrared light. A wall mounted infrared light LED emits the same red glow as well.
I believe that the green stray light from the eyepiece could fog film so I feel that I need to contain this stray light from reaching the film. That is easy enough to do. My question is concerning the red infrared light. Could it also fog film or am I concerned about nothing.
Any physicists out there? I guess I could do some tests but I have been rather busy lately and wanted to try the easier route.
Thanks in advance.
