| The "Surface Maker" Modeling Software package is a DOS-based suite of tools and utilities for analyzing the structure in atomic and molecular surfaces. The program will calculate the positions of atoms in any extended single-crystal surface specified by miller indices, or the surface of single-crystal particles formed by the intersection of planes specified by Miller index. Individual "atoms" can be added or deleted to produce custom structures. "Molecules" may be "adsorbed" to the surfaces in top, bridge and three-fold configuration with any specified orientation. The structures may be displayed as 3-D ray-traced spheres, or 2-D colored-coded circles. The viewing orientation of the structures may be changed to se different perspectives. The Infrared spectra of certain adsorbed molecules may be calculated using the "Site-Specific Coupled-Harmonic-Oscillator Model". The normal modes of the C-O stretched may be analyzed with the "Mode" tool. Kinematic LEED images may be calculated from the surface structures. A new Windows-based version that can run on Intel, Alpha and Mac is planed for future development.
| Optics Library
|
| The "BI Optics Library is a collection of function libraries and tools for analyzing optics systems and devices.
Geometric Ray-tracing, Gradient Index analysis, Diffraction Analysis, Scattering tools for single, multiple, small particle, rough surface and irregular shapes, Black body calculations. Some tools integrate with Excel, Visual Basic and C++ so that you can build custom apps. Windows- and Web-based Tutorials and information.
| Light Designer
|
| The "Light Designer" is a optical design tool for calculating the illumination patterns of lighting fixtures. Layout a pattern of reflectors and refractors and the Light designer will give the radial distribution or distribution projected onto a horizontal surface.
