TracePro 7.1 is the latest release of Lambda’s award-winning illumination and optical analysis software. This release features dramatic new visualization capabilities, new path-sorting, enhanced ray sorting and a new multi-core thread setting.

The new 3D visualization feature displays irradiance, illuminance, CIE and true color plots directly on selected curved and planar surfaces and parts in the system view.

This gives TracePro a considerable advantage over the competition.

LED Lighting Design Using TracePro
Dave Jacobsen, Senior Application Engineer for Lambda Research Corporation will discuss and demonstrate using TracePro for LED lighting design applications. The presentation will last 20-30 minutes, followed by a 10-15 minute question and answer session.In this webinar we will:
• Start with a basic specification and use that as the starting point for our LED lighting design
• Discuss how the specification will influence the choice of LEDs. Can a single LED be used, or will an array of LEDs be needed?
• Use the LED datasheet to create a custom Surface Source Property in TracePro
• Demonstrate setting-up the initial model and preparing the system for optimization
• Show how the new Interactive Optimizer in TracePro can be used to optimize refractive and reflective systems.
• Explain how the Interactive Optimizer can be used in conjunction with the Scheme macro language in TracePro to optimize the placement of LEDs and/or luminaires.
• Validate the design using the analysis tools in TracePro
• Answer your questions in the Question and Answer session

Who should attend:
Current and potential users of TracePro who would like to learn how TracePro can be used as a valuable tool in the LED lighting design process.
2 sessions:  Wednesday June 29, 2011  – 10am EDT (4pm CEST) and 4pm EDT (1pm PDT)

New lighting design Brochure:

Extract: Software for Lighting Design Luminaire and LED based Lighting Design Design of application-specific lighting systems involves adherence to various system performance criteria including spatial and angular light output distribution,uniformity, intensity, and spectral characteristics – as well as aesthetic factors such as lit and unlit appearance. Achieving these criteria quickly with a manufacturable and cost effective design requires modeling software that is powerful,easy to use, and accurate. TracePro, renowned in the scientific community for the accuracy of its simulations, offers lighting designers the confidence that the performance and aesthetics of finished products will concur with the simulated design without costly prototype iterations.


TracePro 7.0

TracePro 7.0 uses multi-threaded algorithms to raytrace on all the cores in Intel or AMD multi-core CPUs. Simulations done on a Dual Quad core computer show raytracing improvement of up to 10 times over previous releases when simulating LED,lighting, display, biomedical and aerospace systems.

The new interactive optimizer is specifically designed for non-sequential design on LEDand illumination systems. The optimizer features a sketch utility for quick design entry, interactive raytrace for design verification, downhill simplex optimizer with interactive entry of target specifications.
Other new features include a re-arrangeable system tree to create assemblies and standard drag and drop operations to arrange parts and assemblies. Two new irradiance options have been added including a new rainbow palette and normalization for stray light point source transmittance calculations. TracePro 7.0 also adds two new RepTile geometries, a flattened and pointed cone for the backlight display simulation.

January 2011

Key Photonics Ltd is proud to announce two major lighting events coming up shortly in the UK. Please put these dates in your diaries if interested.

1. Lighting Design Software Presentation –a joint event from Oxytech and Lambda Research.

Date: Wednesday 2nd March 2011

Location: London (CEME)

Places: Limited

Presenters: Stefano Borsani from OxyTech Srl and David Jacobsen from Lambda Research Corp.

A  free demonstration and presentation of OxyTech’s ground breaking lighting design package LiteStar 4D, which easily and accurately renders 3D lighting schemes, for rooms,  buildings and streets, just click and drag luminaries into the scene. To watch a video demonstration please see:

Plus: Lambda Researches Corp’s powerful Opto-Mechanical 3D Lighting and illumination software package. TracePro is a flexible and powerful ray tracing program based on ACIS, the industry-standard solid modelling kernel. It predicts intensity patterns in candelas and calculates illuminance on any surface. TracePro can model any surface type, and any surface can be made a source of light. TracePro features an easy and fun to use, state-of-the-art graphical Windows interface and strong data exchange capabilities with CAD and lens design software.

Cost: Free

2. TracePro 7.0 illumination Training

Date: Wednesday 13th and Thursday 14th April 2011

Location: Cambridge (University of Cambridge)

Trainer: Dr Brian Blanford

Places: 15 Max

In this intensive short course, you will learn how to analyse real illumination systems using TracePro, many types of illumination will be covered, including light pipes, luminaires, concentrators, and projector illumination. After completing the course, attendees will be ready to use TracePro on their own or attend the advanced Stray Light Analysis or Scheme Programming Courses.  Places are restricted to a maximum of 15 people on this course to ensure closer supervision.

Cost:              £650 per person for both days, including refreshments, lunch and course materials. Held in an intimate learning environment in the picturesque city of Cambridge.


Please contact us for more information and to book your place on one of these great events.

The first Optical Engineering and Design (OED) conference a great success at this year’s Photonex show!

Key Photonics Ltd Director Jake Sharpstone was involved in organising a new part of the Photonex Show this year – the Optical Engineering and Design (OED) conference. With a number of very interesting topics ranging from spectacles for the third world to optical manufacturing; it was also a good opportunity to meet and network with other people in the community. It provides a good platform in the UK for people to get together once a year and discuss the latest topics regarding this fascinating subject.

Key Photonics Ltd would like to thank everyone who was able to attend, for making it such a great success, If you haven’t done so already please join our Linkedin group and keep up to date on information and discussions;

We hope you can join us next year as the meeting grows.

October 2010

If you are involved in Optical Design or Engineering in the UK don’t miss out on our first meeting taking place next Thursday 4th November during the Photonex Exhibition.
