SPA has developed in-house code that allows us to use data from optical design and analysis software, (such as CodeV, Zemax or FRED) and import this data into a rendering engine to generate photo-realistic images of optical system performance. This is often a useful tool to demonstrate how an illumination system will physically appear in real life. It is also useful in evaluating an illumination system in different ambient light conditions or examining how different lights/sources will interact in a scene. Likewise, it is helpful for evaluating the effect of glare or viewing angle in a system or examining the impact of non-uniformities with illumination systems due to light distributions, material properties, or scatter properties. By using optical design software which are traced with nanometer accuracy, SPA can render the radiometric properties of a system to nanowatt precision. The model is only limited by the information we have about the optical properties being modeled.
