Import ANSI/IESNA Photometric Data To TracePro

By Lambda Research Corp.

With TracePro® Opto-Mechanical Design Software's IES Import Utility
TracePro's IES Import Utility helps users import photometric data in ANSI/IESNA standard electronic file formats to generate TracePro File Sources and Surface Source Properties. This utility is for use with all TracePro editions.

IESNA Standard File Format
The Illuminating Engineering Society of North America (IESNA) publishes "IESNA Standard File Format for the Electronic Transfer of Photometric Data and Related Information." The most recent publication, LM-63-02, was ANSI approved September 12, 2002 and is available at www.techstreet.com. The TracePro IES Import Utility adheres to this most recently published standard. For a detailed description of all file data, please refer to the copyrighted published standard.

The IES Import Utility supports Photometric Type B and Type C. Refer to IESNA-75-01 for a detailed explanation of goniometer types.

Modeling Sources with TracePro
TracePro
TracePro is a comprehensive, versatile software tool for modeling the propagation of light in opto-mechanical systems. Models are created by importing design files from a lens design program or a CAD program or by directly creating the solid geometry in TracePro. Optical and mechanical properties are applied to materials and surfaces. Source rays propagate through the model with portions of the flux of each ray allocated for absorption, specular reflection and transmission, phosphorescence, and scattering.

From the model, analyze:

• Light distributions in illumination and imaging systems
• Lumens exiting, absorbing, and incident at the component and system levels
• Candela distributions
• Optical efficiency, luminance and radiance metrics
• Luminance effects and lit appearance
• Fluorescence effects of phosphors
