Ansys Speos

Ansys Speos predicts the illumination and optical performance of systems to save on prototyping time and costs while improving your product’s efficiency and provides an in-depth understanding of how light works within designs.


A best-in-class solution, its unique human vision algorithm simulates the effect of light within an optical design on any materials around it in real-world scenarios.


Where every detail matters, Ansys Speos is illuminating the path towards a brighter, safer, more connected world.

Ansys Speos uniquely simulates a system’s optical performance and evaluates the final illumination effect, based on human vision.  In industries where optical performance and design are critical, Ansys Speos delivers an intuitive and comprehensive user interface, enhanced productivity with use of GPUs for simulation previews and easy access to the Ansys multiphysics ecosystem.
