Our primary design tool for non-sequential (illumination) ray tracing is Zemax. Using Zemax, we model millions of rays of light from the emission source, through and off of materials and to the target pattern. This allows use to simulate reflections, scattering, efficiency, and uniformity.
After a design is complete, OFH helps clients find the right manufacturing partner based on required production methods and materials. The most common delivered designs are custom TIR lenses and reflectors.
