FRED Versions 6.100 and Turbo
Oct 2007
Photon Engineering LLCRequest Info
TUCSON, Ariz., Oct. 26, 2007 -- Photon Engineering LLC has launched version 6.100 of its FRED 6.x series optical engineering software. FRED is an advanced 3-D CAD optical engineering software program capable of simulating the propagation of light through virtually any optical/illumination system, the company said.

The 6.100 release features major enhancements to FRED's ray tracing and beam propagation speed and modeling capabilities. According to Photon Engineering, this version is a tremendous value to optical/illumination engineers who need to trace unlimited number of beams or rays on today's multiple core PCs for the fastest nonsequential ray tracing available. That ability, coupled with FRED's new CAD import capabilities to reduce NURB (nonuniform rational B-splines) complexity with user definable accuracy makes FRED the product of choice for realistic optical and illumination modeling.

This version has added two new scatter models, tabulated PSD (which reads power spectral density measurements) and a K-correlation model, making FRED a leader in terms of the number of scatter models and the capability to model both spectral data and scatter degradation over time, the company said.

FRED's new virtual ray buffer now stores rays automatically to disk after reaching a user definable threshold as needed. The maximum number of rays in FRED is now limited only by available computer disk space.

The new beam propagation enhancements include new source creation capabilities and improved propagation features that are well-suited for the biomedical, solid-state and high-power laser diode markets. FRED's flexibility in defining well-formed beams includes the ability to directly import measured data from beam profiler, create custom fields using its field synthesis spreadsheet, and use its detailed complex source dialogs to define higher order Hermite and Laguerre TEM Gaussian beam modes, Photon Engineering said.

The general term for the application of light to a subject. It should not be used in place of the specific quantity illuminance.
Pertaining to optics and the phenomena of light.
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
A geometric representation of a light path through an optical device; a line normal to the wavefront indicating the direction of radiant energy flow.
ray tracing
The mathematical calculation of the path traveled by a ray through an optical component or system.
