What is FRED?

FRED Optical Engineering Software simulates the propagation of light through any optomechanical system by raytracing. Whether your design is imported from CAD, a lens design program, or constructed from within the software, FRED provides engineers with the essential tools for virtual prototyping of optical systems.

FRED is not restricted to any one class of problems. With the ability to propagate both coherent and incoherent light and assign realistic surface properties to every component in your system, FRED can be used for a diverse range of applications that include:

  • stray light
  • laser applications
  • illumination and non-imaging optics
  • imaging systems
  • multi-wavelength systems
  • thermal imaging
