Radiant Source Models
Create powerful design insights with simulations based on actual measured data. Access 600+ light source models representing all major manufacturers. Optimize results with customized ray sets generated directly from the Radiant Source Model.
Zemax Premium gives you access to the most accurate method of modeling optical sources available anywhere: the Radiant Source Model. Premium users have access to download Radiant Source Models from our online library while the Premium key is in support.
These are measurements of the spatial and angular characteristics of the source, and give accurate results in both the near and far field. Zemax Premium includes access to the online Radiant Source catalog of light sources, which is under constant development, with new sources being added regularly. Just choose your manufacturer:
then source type and model number, and you can download the RSMX file directly to your computer.
The real benefit is that you can now generate rays within the exact ranges you need. Many manufacturers make ray sets available for download, but by using the RSMX directly you can generate rays that exactly meet the needs of your
The ray-trace shows lots of detail, including the bonding wires being visible in this close-up view:
You can generate as many or as few rays as you need over whatever ranges you require to get the most accurate illumination simulation results!
