RayLab 3.0 has just been released in the App store.
This upgrade is a major step up in capability for RayLab. You can now create full 3 dimensional optical models. The model can be easily rotated and viewed from any direction.
The upgrade also adds various non symmetric elements such as cylindrical lenses and prisms.
Zemax import functionality has also been enhanced to handle 3D models.
Many of the analysis and report options which were available in 2D models are also available in 3D models.
