Radiant Vision Systems Radiant Source Model™ Files RSM

Radiant Source Models (RSMs) provide the most accurate method of modeling the near-field output of real light sources for use in optical and illumination design software. They are used for light source analysis to investigate fine scale performance for light source design and development and for optical and illumination design to create accurate performance simulations. RSMs can be used by optical and illumination design engineers to simulate virtually any type of light source, including LEDs, fluorescent lights, arc, tungsten halogen, and HID lamps. When paired with a near-field measurement system such as a Radiant Source Imaging Goniometer®, the measurement data collected by Radiant's ProSource® Software is formatted as an RSM file. RSMs can be used to generate ray sets that are compatible with leading optical and illumination design software programs such as ASAP®, FRED®, LightTools®, LucidShape®, Photopia™, IES TM-25, Opticad®, OSLO®, SimuLux®, SPEOS®, TracePro®, and OpticStudio™ (ZEMAX), as well as general file formats. Complete information for light source performance evaluation It is often difficult or impossible for an engineer to obtain all of the data necessary to accurately model a light source through traditional means, such as combining various shapes in optical design software and applying estimated luminance values to each component. An RSM solves this by providing the full luminance field (both angular and spatial distributions) of a representative light source. These measurements are obtained using a Radiant Source Imaging Goniometer® (SIG) measurement system.
