Yeah I started a lengthy thread a while back on here regarding that residual-short wavelength focus shift thing. I ran detailed tests (initial tests posted in the thread) and found zero evidence of it in my system with the papers I use. There was some disagreement in the thread regarding whether the amounts of UV-range light (if any) in quartz halogen systems is anything more than trivial. In the end I'm not sure we answered that particular question.
I think you're probably right though, I can't see how it would hurt to use UV glass. In fact, I'm just thinking, doesn't the base of TMax 100 filter UV? In the end I guess as long as you standardize for a certain set of equipment you're fine.
Thanks Bob and Sal. I'll include this particular glass in my experiments.
