WHAT IS PHOTOPIA ?
photopia™ is a fast and accurate optical design program that produces comprehensive performance evaluations for non-imaging optical systems. photopia allows you to produce virtual designs in a fraction of the time and for a fraction of the cost of physical prototypes.
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®. With photopia for SOLIDWORKS®, you can perform raytrace simulations directly on your assembly models. From adding lamps and assigning materials, to setting and viewing output, everything is done inside of SOLIDWORKS. You maintain all the ease of working in SOLIDWORKS®, with no need to learn another CAD program. This is complete single window optical-mechanical integration. No need to link, bridge, or export files for your analysis and potentially lose fidelity. Work in your familiar CAD interface to increase productivity and get your work done faster.
photopia is designed so that you don’t need an optics PhD in order to understand the software. Use our library of pre-defined lamps and materials, use our design tools to generate optical geometry based on your design requirements, and get output in industry standard formats.
photopia has an integrated CAD system so that you can create and optimize your optical design without going back and forth from your CAD system. You can also import your mechanical parts from leading CAD software using STL and DXF/DWG files. This version includes all the lamps and material libraries, the ray tracing engine and allows you to perform your photometric simulations very quickly. Once you have an optimized design, you can export the geometry back to your CAD system as a 3DM or DXF/DWG file. photopia Stand-Alone also includes Script and batch capabilities that gives the ability to automate some tasks and to simulate several scenarios at once.

Photopia includes the most comprehensive library of lamps for the architectural lighting industry. The current library includes over 1,900 source models with a large selection of LEDs, and also includes sun and sky dome models for daylighting device designs. This extensive library avoids the need for the user to create their own lamps and guess at their properties. Having accurate source models is essential to getting accurate simulations of the entire luminaire. Other programs that rely heavily on ray sets may not be as accurate as models in Photopia’s library. For more details, see Mark’s Jongewaard paper about light sources modeling.
Other software allows you to define BRDF (BSDF) data via parameters of various mathematical functions, but knowing what parameters to set is an open question and even then the scattering behavior of many materials isn’t accurately represented by a mathematical function. Although BRDF/BTDF data for standard materials is now being distributed by manufacturers, it is also very important that the optical software company is able to measure custom materials, such as formed aluminum with various levels of polish and anodizing processes. LTI Optics has provided this service since the late 1980’s, longer than any other company, and has more experience in characterizing the important optical properties of materials. Having measured BRDF/BTDF data for the actual materials used in your products is critical to being able to produce accurate simulation results.
Most Parametric Modeling relies on primitive geometry like lines or arcs or splines… but none of these directly relate to how you want to aim light. Our Parametric Optical Design Tools (PODT) give you a direct way to create and manipulate geometry based on how you want your final distribution to look. PODT can be used on anything from simple revolved reflectors to complicated lofted lenses made of multiple control profiles. PODT is all about getting you to a final design quicker. We use these tools everyday on our projects and they significantly reduce the amount of time it takes to optimize a design.
