photopia for SOLIDWORKS®

UV optical design software

Photopia is the perfect optical design software for your UV illumination optical designs. Whether you are designing a UV air or water purification system and need to analyze the irradiance pattern, or creating a UV light source for UV curing in adhesives or printing, Photopia will help you design the best UV optical system in the shortest amount of time.

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®.

The Photopia library includes lamp and material data for UV applications, and the Parametric Optical Design Tools help you create and optimize reflector and lens shapes for controlling the illumination pattern of your UV device.
