Originally, I posted full prescriptions, but thought better about the
amount of
bandwidth used. The reason I settled on OSLO distribution via my site is
the inferred wide-spread use of it for design within the ATM list community;
I personally don't like OSLO and think of it as too buggy, but it seemed
to have
become the defacto "standard"; apparently only seemed. The other reason
I settled
on a single distribution is that I only have a 10 Mbyte allowance on my
site.
Distributing pictures, spot diagrams, etc. would chew up space too quickly.
Now that I've gotten used to sending just the OSLO file to my site, I've
become a tad lazy, letting others examine or modify the OSLO on their own.
However, it would not take too much more to distribute both the OSLO
prescription
and the textual prescription generated by ZEMAX (file name extension
".txt").
See the example below that I provided only for discussion; it would not
normally
be distributed via mail. I have limited to the Surface Data and Surface
Detail
portions. The surface data summary provided the information mentions by
Vladimir.
The surface data detail provides the full expansion for figured surfaces
as well
as aperture specifications, but can get a bit "wordy".
