One of the issues with GNU Optical is that the user guide is not
comprehensive enough, and it is a bit difficult to work out how to use
all the available features. So I have created a simple interface that
takes in text file containing lens specifications and generates
output. I am still refining this but please have a look at the input
and outputs here:

Commercial packages are really expensive.

There is a free optical design package called KDP that only works on
Windows, and has a clunky UI that sometimes crashes.
I have tried using it but I do not quite understand how to use it
correctly. The software is written in very unreadable and
unmaintainable Fortran. Some brave folks are trying to modernize the

Another project that I recently became aware of is a package written
in C by Don Wells from NRAO.
I have a version of this here:

Final one worth mentioning is another C++ project similar to GNU optical:
