FRED Illumination Systems

FRED has all of the tools necessary for modeling and analyzing illumination and Non-Imaging Systems.

Lawn LampFRED is fully capable of modeling LED's, bulbs and arc sources for integration with optical components and light distribution analyses.

Accurate illumination system design begins at the source, and no other optical systems design and analysis package offers more flexibility than FRED for prescribing a starting ray distribution. In addition to its default source types, users have the ability to precisely control ray positions, directions, power, wavelength, and polarization.

Source power can be defined radiometric or photometric with spectra in order to perform accurate irradiance, intensity, illuminance, luminous intensity, and color image calculations, among others.

The built-in multi-variable optimization capability allows rapid design convergence for a variety of merit functions with access to every geometrical parameter in the model.
