Subject: RE: BS: What Do Physicists Think About? II
Thanks, but no thanks, Bill D. One rare occassions if I'm lazy I'll use software somebody else wrote, but that's hazardous, because programs often don't things the way I like them done, and results are often misleading.

For one-shot through I use True Basic now, but for something like 3D raytracing through a system, (I do 225 rays at a time, through a system of as many as 60 optical surfaces), I wrote my own Fortran Program. I'll use it to check out the design of the transfer optics I'm working on now for a high resolution FTS spectrometer at Battelle Northwest labs.

The multiple reflection absorption cell will just be a copy of the NIST one I did, because it's zero astigmatism, and nobody's beaten it yet for long path length. Last info I need just arived by email, so it's off to my 3 concave mirror system Basic program to figure out the focal lengths I need, the to my ray transfer matrix program to find the diameters I need for the mirrors.
