Hi, thanks for help. I'm an electronic enginner working in the
automation idustry, where I have to deal with lasers and scannig
heads. I've been asked, as I'm getting deeper inside optics by my own,
to take a look to a pre-focused scanning head project made few years
ago for a CO2 laser. The system has three elements, a moving biconcave
followed by a closed doublet with a meniscus and a plano-convex ZeSe
lenses, but has not been done for constant spot size all over the
field. I'm trying to get some tips, suggestions or whatever to, on one
side, learn the way such a constant spot size configuration should be
done and, on the other side, to better understand optics. I ask you
even more, some titles you think I should read to build good optics
knowledge funded on solid basis, at the moment I'm reading Smith,
Fischer, Hecht, Pedrotti, Siegman, I've got Born-Wolf as a reference
and look forward to get Goodman.
Thanks, Marco
