photopia for SOLIDWORKS®

horticulture optical design software

Photopia is the perfect optical design software for your horticulture optical design projects. Photopia has a range of white and RGB LEDs that are used for LED horticulture lighting, and has output in photon flux and PAR for you to analyze your product's output. You can ensure that your colors are well mixed and that your horticulture light provides adequate light levels.

Photopia also provides a set of Parametric Optical Design Tools to help you create and optimize optical surfaces that direct light into an appropriate pattern for your application. Once your design is complete, you can save out PAR data on grids and export an IES file to share with specifier.

Photopia includes a built-in CAD system or is available as an add-in for SOLIDWORKS®. Our standalone CAD system interfaces with packages such as SOLIDWORKS®, AutoCAD®, Pro/Engineer CREO®, SolidEdge®, and Inventor®.
