fDesc[0] = "CyberRay is a professional optical and charged particle beam simulation package. It offers exceptional flexibility, including the ability to position three dimensional optical elements in arbitrary positions and orientations. The model includes dispersion, short pulse effects such as group velocity dispersion, geometric aberrations to all orders, Gaussian optics, graded index materials, and radiation processes. A wide variety of optical elements can be modeled, including spherical and cylindrical lenses of all types, gratings, prisms, spherical and parabolic mirrors, and more. For the same affordable price, CyberRay also includes a fully capable charged particle optics model. The charged particle and photon models are fully integrated. The pro-version includes a sophisticated three dimensional particle-in-cell model for space charge effects.";
