DIFFRACT ™ is a powerful software package that helps you simulate both coherent beams and incoherent beams of light as they propagate through an optical system. Many general-purpose features of DIFFRACT ™ enable you to analyze and study diverse optical systems. DIFFRACT ™ empowers you to accurately tolerance your optical design by stepping through a set of adjustments for any part of the system and allowing you to inspect the resulting optical patterns at various cross-sections of the beam.

Using DIFFRACT ™ you can:Completely and accurately analyze your optical system.Fully keep track of polarization, inspecting the amplitude, phase, and polarization state of the beam at various stages throughout the system.Tolerance your optical system from source to detectors including: lasers, lenses, mirrors, polarization optics, diffraction gratings, prisms, apertures, phase/amplitude masks, multilayer stacks, detectors, and more.Study some of the most fascinating phenomena of classical optics such as: the Talbot effect, optics of biaxially birefringent crystals, surface plasmon excitation, magneto-optical Faraday and Kerr effects, the principle of holography, evanescent coupling through frustrated/attenuated total internal reflection, self-focusing and filamentation in non-linear media, electromagnetic confinement in resonant cavities, the phenomena of internal and external conical refraction, the Goos-Hänchen effect, and many more.

Distribution of intensity at various cross-sections of an astigmatic focus-error detection system.Focusing of polarized light through a tilted glass plate using an aspheric singlet.Simulated patterns of grooves, preformat pits, and recorded marks on various optical disk surfaces.Coherent imaging. Geometric-optical ray tracing and wavefront reconstruction from traced rays.Interferograms showing several third order (Seidel) aberrations of a beam.Double refraction in optically anisotropic media.Diffraction of focused beam from a tilted grating.Conical internal refraction. The Goos-Hänchen effect.Focusing a beam of polarized light through a slab of aragonite (biaxially birefringent crystal).


DiffractGUI™ has been developed to facilitate working with DIFFRACT™. It primarily deals with DIFFRACT™’s COMMAND.DAT file. DiffractGUI™ can display and change in various ways the contents of COMMAND.DAT. Furthermore, it can show and change in a ３D-mannergeometric-optical systems and it can draw as bitmaps or as ３D-reliefs DIFFRACT™’s output data-files. All output files created by DIFFRACT™during a session can be visualized within DiffractGUI™’s environment.The program is designed as an MDI-Application, able to run under Windows XP, Vista, and ７. This means that there may be more than one COMMAND.DAT file (hereinafter referred to as “document”) opened simultaneously inside DiffractGUI ™. To each such document are attached eight view-windows, which can be hidden or shown independently ofeach other. Some of these views show (in different modes) the content of the COMMAND.DAT document, while others can open and display the contents of DIFFRACT™’s output files.

These and many other optical systems can now be modeled and analyzed inDIFFRACT ™. From the simplest system consisting of a single optical element,to complex systems with tens of optical surfaces, lenses, mirrors, gratings,polarization optics, etc., the fascinating world of classical coherent,incoherentoptics is yours to explore.Here is a list of the menu options presently available in DIFFRACT ™ :

M.Mansuripur Professor of Optics Laboratory University of Arizona is a worldwide authority Simulation Analysis of physical optics.DIFFRACT™ is a typical software developed by him, has many features not

found in other commercially available software. Therefore, it is used in many optical fields.Also, Sim３D_Max ™ solves Maxwell equations for a variable time and space in the Finite Difference Time Domain (FDTD) method for the structure of the action of the light wavelength or less.Sim３D_Max ™ software, micro and macro data exchange is possible with DIFFRACT™ .Sim３D_Max ™ software are equipped with user interface GUI, the ３D-CAD and significantly reduce computation time by calculation of the standard cluster configuration and uneven spatial grid.In addition, we offer high performance and shorter computation time significantly by Acceleware™, we have a good reputation in a wide range of fields.“Classical Optics and its Applications” by Prof. M. Mansuripur is published from Cambridge university press shows various optical phenomena using DIFFRACT™ and Sim３D_Max™ This book is well read for users can understand the nature of light.
