Every software package contains a full set of examples suitable for that version and are installed with the software. If you see examples here that are not in your installation you should consider updating to a later version of the software. These examples can be used by beginners and advanced users for product evaluation, teaching purposes, and self-training.

How to define a 3D elliptical source
To define an optical source in Optical 3D is a little more complex than one in Optical 2D. The following steps are needed to define an elliptical beam using the BEAM statement.
The origin of the beam is defined as (X.ORIGIN, Y.ORIGIN, Z.ORIGIN), similar to 2D, but an additional two parameters angle and theta are also needed to define the orientation of the beam. The angle parameter specifies the angle of the beam relative to the device X axis and the theta parameter specifies the rotated angle of propagation relative to the X-Z plane.
The center of the elliptical source can be offset from the center of the beam coordinate center using the parameters xcenter and zcenter but in this example we have chosen the center of the elliptical source to coincide with the origin of the beam system.
After defining the beam coordinate system and the location of the elliptical beam, it is necessary to define the elliptical radii of the beam using the parameters xradius and zradius.
The sampling frequency of the source beam must now be chosen. The samples are taken along each of the beam front principal axes, ie the x and z planes, in constant steps. The number of sampling points in each axis is defined by the parameters nx and nz.
Finally the wavelength of the light is defined, the front side reflections are switched on with the parameter metal.reflect so that all metal regions act as perfect optical reflectors and the parameter raytrace identifies a file within which the traced rays are saved so they can be plotted with Victory Visual.
