Optical Design Software
for SOLIDWORKS and Rhinoceros.

Design and analyze a wide range of non-imaging optical systems directly inside your CAD model.

Photopia optical design software is perfect for your design task:

luminaire optical design

illumination optical design

non-imaging optical design

UV curing and disinfection

daylighting optical design

IR irradiation optical design

industrial system optical design

optical design for sensor systems

optics for consumer devices

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 is designed so that you don't need an optics PhD in order to understand the software. We have a library of pre-defined lamps and materials with all their optical properties. Generate optical geometry based on your design requirements with our Parametric Optical Design Tools. View industry standard and customized output. Do all of this directly inside of Solidworks or Rhino.


Parametric Optical Design Tools (PODT) in Photopia

Parametric Optical Design Tools

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.

Lamp and Material Library

The core of any optical simulation is accurate ray generation and accurate ray interaction, in other words, an accurate lamp model and accurate material properties. Instead of relying on our user to adjust theoretical material equations or use simplified lamp models with only ray data, we've spent the time to measure, analyze and model all 1900+ lamps and materials in the Photopia library ourselves. With 25 years of history in raytracing, we know what is required to produce an accurate simulation. We use the software everyday in our own design work, so we have to trust it.

Relevant Output

Photopia generates fully compliant IES, TM-14, and EULUMDAT files with every raytrace. Illuminance planes can be used to evaluate beam smoothness, full 3D ray paths can be used to identify areas for design optimization, and a host of plots can confirm your design. Photopia also has the latest output requirements like IESNA TM-15 and BUG ratings. There's also a report for analyzing color uniformity which includes industry relevant metrics like color change over beam and field angle as required by EnergyStar and DLC.

CAD System

Photopia is an add-in for SOLIDWORKS and Rhino, allowing you to work within a familiar environment.

Inventor, Creo Parametric, SolidEdge, and other CAD users will typically use our Photopia for Rhino add-in. Rhino imports and exports a wide range of formats, making it easy to work with any CAD system you have. LTI Optics can sell Rhino in a bundle with your Photopia purchase.
