Real world uses of Photopia
Use Photopia to design and analyize non-imaging and illumination optical systems directly in SOLIDWORKS and Rhinoceros
Photopia is fully integrated into Solidworks and Rhino, allowing you to analyze and create native geometry.
LTI Optics has taken great care to fully measure and model a library of over 1405 common light sources and 1544 common materials.
Photopia will generate optical geometry based on where you want to aim light, making the process of creating an optic from scratch quick and easy.
Over the same development time period, with Photopia you can test and iterate over many more design options, allowing you to get to the most optimal design more quickly.
Expert consulting from the creators of Photopia, the leading optical design software.
