I have ZEMAX-SE and am trying to design a collimator for a laser
diode. Is it possible to set up a source in ZEMAX-SE (I know you can
in EE) that has divergence of different angles in the different
planes?

Thanks
Tim

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

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.

First, let me thank you for all your help.

Would it be possible to get an example of what you fill into the merit
function editor? I haven't been able to replicate what you
suggested. I am trying to get a divergence of 9 degrees in one
direction and 19 degrees in the other.

Thanks
Tim

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.
