Leaders in providing tools and services for design and virtual prototyping of optical systems.

Since 1997, Photon Engineering has been providing clients with high quality solutions and services in optical engineering. FRED Optical Engineering Software is used by thousands of engineers worldwide for simulating the propagation of light through opto-mechanical systems by ray tracing, and is an essential tool for virtual prototyping optical systems.

FRED Optical Engineering Software

FRED Optical Engineering Software has allowed thousands of users worldwide to successfully simulate the propagation of light through any opto-mechanical system by raytracing and is the essential tool for virtual prototyping optical systems. FRED can be used for a wide variety of applications that include stray light analysis, virtual prototyping, laser beam propagation, illumination system design and much more.

Released in 2019, FREDmpc is the most recent addition to the FRED suite, and allows raytracing and analyses to be performed on GPU boards for radiometrically precise optomechanical analysis performed orders of magnitude faster than software that uses conventional multi-threaded CPUs.

FRED Editions

Core Capability

FRED Classic provides the core capability to propagate both coherent and incoherent light and assign realistic surface and material properties to every component of your system. FRED is a powerful software solution that can handle the most complex opto-mechanical projects.

Feature Highlights Include:

  • Non-sequential and sequential raytracing

  • Coherent beam propagation

  • Multi-threading on up to 17 CPU threads

  • 64-bit architecture

  • 3D graphical interface for model construction and verification

  • Lens import from ZEMAX®, CODE V®, and OLSO®

  • CAD Import/Export (IGES, STEP, OBJ)

  • Built-in scripting environment

Design with More Power

FRED Optimum includes all functionality of FRED, and provides engineers with more power by allowing the ray trace use up to 127 CPU cores, and across a distributed network of computers. Other essential tools include a multi-variable optimizer and sensitivity analysis.

Includes all features of FRED, plus:

  • Multi-threading on up to 127 CPU threads

  • Multi-variable optimization capability

  • Parameter Sensitivity Analysis

  • System Configurations Manager

  • Parameter Pickups

  • Distributed Computing

Save Time (…as in, lots of time)

FREDmpc is our most powerful edition of FRED and builds on the feature set of FRED Classic and FRED Optimum by offering the ability to accelerate your traces using NVidia GPU's which provides the ultimate speed boost to your calculations. Tracing faster means you save time and can perform more iterations on your system designs.

Our customers are currently using FREDmpc to:

  • Perform straylight calculations in a few hours that used to take several days.

  • Run Illumination simulations with many millions of rays in seconds.

  • Accelerate coherent calculations in the recombination step.

Recently FREDmpc was used in what we believe was the first Trillion-ray trace! We’d like to give you more details on that but, well, we can’t - but it was super exciting!

Spectacular customer service, very friendly and knowledgeable.

FRED User
Technical Support Feedback

On a quick note, the FRED tutorial courses, especially the Mastering Stray Light course, have been a tremendous asset to us here across multiple programs. We are continually trying to send people to Tucson to attend these courses, as the knowledge gained when combined with the FRED software, is an unparalleled combination. I really appreciate the continued support from both yourself and the rest of the Photon Engineering team. Keep up the great work!
