OK, I'm a novice here, but have been recently intrigued by the PD/PT process, an d as usual my mind, or what's left of it after the 70's, started wondering why a n enlarger couldn't be used to produce larger prints off a 4x5 neg. That's when I came across the quote below in a previous thread.
"the optics in an enlarger lens are not designed for UV light, which is the rang e of wavelengths that these mixtures are sensitive to. So, you would need to sea rch out some highly specialized enlarging lenses that will focus UV wavelengths (and not absorb or reflect them, as most optical glass tends to do.)"
OK, I didn't know enlarger lenses or heat absorbing glass absorbed UV light, and if it's true then I'm at the preverbial end of the line, but if it's possibly n ot totally correct, might it be possible? I'm using an old Bessler 4x5 with a co oling fan. Thoughts.
