Another question, how to I change the rotation of a cylindrical lens?
ZEMAX just puts it in a certain way and I can't seem to get it to
rotate.
Thanks for the help,
Tim

I have ZEMAX-SE and am trying to design a collimator for a laser

in EE) that has divergence of different angles in the different

Tim,
What I do in ZEMAX is use two orthogonal paraxial cylindrical lenses
and the RAID command in the merit function to set the orthogonal
divergences. I also set the apodization to Gaussian with a .6 to .85
to match the beam profile of a diode.
There are many commercial solutions for diode collimation, almost
every diode laser manufacturer sells a collimated model, or
collimation kit including the big catalogs. You may not need to
design a collimating asphere.

the paraxial lenses are defaulted to align with either the x or y
axes, for arbitrary rotation use the tilt/decenter element tool.
Zemax knowledge base has an article on how to tilt/rotate/decenter
elements.
