RayLab 2.22 has just been released in the App store.
The main new feature in this release is Ray Transfer Matrix (ABCD) analysis. I am quite excited about this feature. In addition to the basic Ray Transfer Matrix which is described in most introductory treatments of the subject, RayLab can perform some more sophisticated RTM calculations allowing it to be used with non axial optical systems. It took some time to work out and implement the more general techniques. Thanks to professor Lee Townsend for pointing out some very useful references on the subject.
