As a development platform of optical mechanical integration, Fred can be used in every link of optical design process, including initial concept verification, integration of optical design and mechanical design, comprehensive analysis of virtual prototype, rapid tolerance analysis and optimization of model parameters, and integration of supplier's catalog into software for processing and system debugging. 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.
Application Area
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
Imaging systems
Multi-wavelength systems 
Illumination and non-imaging optics
Thermal imaging

What is FRED MPC?
FRED MPC is a version of Photon Engineering’s FRED Optical Engineering Software package that allows ray generation, ray tracing and analyses to be performed with GPUs and is the result of our continued investment in leveraging cutting-edge technology for fast, radiometrically precise optomechanical raytracing and analysis.
GPU hardware technology, of which NVIDIA is an industry leader, allows for thousands of processing units running in parallel to be contained within a single workstation. GPU hardware (and software) is rapidly advancing, is highly scalable, and has a relatively low entry cost when compared to distributable CPU based networks. By simply adding, or upgrading, the GPU board in a PC, raytracing and analyses with FREDmpc can be performed orders of magnitude faster using GPUs than with conventional multi-threaded CPUs.
FRED MPC is not a standalone product, it is an extension to the existing capabilities of FRED and FRED Optimum.  All of FRED’s modeling, raytrace and analyses capabilities can be applied in the usual manner with the addition that raytracing and analyses can optionally be performed on the GPUs upon request.
Is it fast?

Really fast?

How does FREDmpc work?
From a program structure perspective, features in FRED which are supported on the GPUs have two implementations in the source code base; one version written specifically for CPUs and one version written specifically for GPUs. When a request to use the GPUs is made, the FRED model on the CPU is passed through a translator that maps each supported FRED feature into its equivalent GPU version.  As Photon Engineering continues to invest in GPU code development, the capabilities of FRED MPC will expand with each new release.
In FRED, performing raytracing and analyses on the GPUs can be accomplished with a single mouse click.  The model translation, raytracing and analyses happen transparently to the user with no additional interaction required.
When should I use FRED MPC?
Are you tracing large numbers of rays?
Do you often have to run calculations overnight or over multiple days?
Are your models often made up of thousands of surfaces?
If so then FREDmpc could be beneficial. The question is: how much is your time worth?
