Sorry, off topic and all, but a bit of a sore point for me.

Not everyone in the world uses windows or mac. There are many other
browsers in the world, and it's much better to design for standards and
graceful degradation than to enforce a "one world" philosophy of
computing.

Just be glad you didn't mention anything about those cursed pdf
files....

To try to inject some sort of 3d thread into this letter, I have as my
second viewer a kodaslide I. Now of course, I could pay a visit to our
esteemed Dr. T, purchase his kodaslide book (which I'll probably do
anyway), as well as some nice revere lenses (which I'll probably do
anyway), but where would the adventure be in that.

So I got the Edmund Optical catalog, and I'm getting the pages all dirty
trying to figure out what exactly I need. This is essentially what I've
been able to figure out for myself:

20 mm diameter
~40 mm efl (as notated in the catalog)
achromatic doublet or triplet

Is that right? Should I be looking for steinheil, or hastings, and what
would the difference be? Do I really need to wade through another
Kingslake book to figure this out?
