Software for design and analysis of illumination and optical systems.

TracePro® combines Monte Carlo ray tracing, analysis, CAD import/export, and optimization methods with a complete and robust macro language to solve a wide variety of problems in illumination design and optical analysis.

TracePro Advantages

Solid Modeling 

Using TracePro’s user-friendly, 3D CAD interface you can create TracePro models by importing lens design or CAD files, or by directly creating solid geometry. TracePro uses a true solid modeling engine to ensure consistent and robust models.

Performance & Accuracy

TracePro’s ray tracing engine is fast and accurate. Exact ray tracing to all surfaces even imported splines ‒ no missed intersections or “leaky” rays.

Analysis Mode ray tracing, unique to TracePro, is a very powerful capability that creates an interactive environment. With Analysis Mode you can analyze every surface and object both visually and quantitatively.

Predefined Optical Properties

Hundreds of pre-existing properties have been developed and can be applied to a TracePro model.

Properties include: materials (optical glass, plastic, infrared materials), surface properties, bulk scatter and fluorescence.

Intuitive User Interface

TracePro sets itself apart from other software solutions with its friendly and quickly learned CAD-like interface.

TracePro’s famously easy-to-use GUI means a short learning curve and no re-training.

Imaging Optics

Non-imaging Optics

TracePro’s Customization

Choice of Ray Tracing Modes

Analysis Mode is used for tracing a moderate number of rays (hundreds to thousands) with complete freedom to analyze results on any surface interactively.

Simulation Mode is used for tracing many rays (millions, billions, or trillions) for an accurate simulation of your system.

Source, Material, Fluorescence, and Surface Property Database

Properties can be defined with customized parameters or applied from TracePro’s catalog of commonly used, commercially-available sources, materials and coatings.
You can also add your own properties to the database to streamline the modeling process.

Versatile Programmability

TracePro’s powerful macro language enables you to automate many analysis and design tasks. The Macro Recorder is a great tool for learning the Scheme programming language, and for jump-starting your programming task. Most functions that are available in the TracePro user interface are also available as macro commands.

You also have access to the underlying solid modeling engine for low-level access to geometry creation, editing, and analysis. Scheme is a full-featured programming language, offering looping, branching, file I/O, and more.

Illumination

TracePro offers luminaire and illumination designers the most accurate and comprehensive design environment available.

Luminaire design requires strict adherence to system performance criteria, including spatial and angular light distributions, uniformity, luminance, and spectral characteristics, along with esthetic factors, such as lit and unlit appearance.

Interactive Optimizer

Our intuitive and easy-to-learn interface empowers our users to rapidly and efficiently achieve their design goals. Our 3D optimizer enables you to sketch a starting design with interactive ray-trace, then optimize using a wide range of operands. The Photorealistic Rendering feature completes the virtual prototyping process, enabling TracePro users to shorten the design-build-test cycle. Usually only a final prototype is required.

RepTile™

The RepTile (Repetitive Tile) feature enables procedural modeling of repeated microstructures that are used for diffusers on display backlights. These diffusers are too complex for explicit modeling in CAD software, but can be ray-traced efficiently in TracePro Expert, and optimized using the Texture Optimizer.

Photorealistic Rendering

Accurately simulate the lit appearance of your product, and reduce costly trial-and-error prototyping.

Whether you are designing an instrument panel, light pipes for switches or indicators, or automotive lighting, TracePro can accurately model the appearance of your design.

Imaging Optics

TracePro is used to analyze non-imaging aspects of imaging systems, such as stray light, polarization effects, thermal loading, bulk scatter, and fluorescence.

Solar Emulator

TracePro’s Solar Emulator and optimization features ensure solar collectors perform at peak efficiency.
Analyze your design for a specified period of sun travel with multiaxial tracking and irradiance for both direct and indirect sun contribution.

Non-imaging Optics

Light guide and display designers can be confident that TracePro will accurately predict the performance and aesthetics of finished products with fewer costly prototypes. TracePro offers equipment and industrial designers the confidence that the simulation will accurately predict performance without costly prototype iterations for a wide variety of technologies.

Stray Light Analysis

TracePro was originally developed for NASA for stray light analysis of space telescopes and remote sensing systems, and it continues to be a strength of the software.
With advanced path sorting, ray visualization, and optimization, TracePro takes the drudgery out of stray light analysis and design.

Applications

Light Pipe Design

Light pipes or light guides are commonly used in consumer electronics, avionics, instrument panels, switches, indicators, and display devices. Light pipes are clear, polished plastic devices molded as a single piece, and are used to guide light to where it is needed.

Automotive

Automotive designers use TracePro to integrate LEDs, HID lamps, and incandescent lighting into cars, trucks, and commercial vehicles. LED-based headlamps are now used on many vehicles. These high-power LED systems must be analyzed to verify performance.
