Photopia is a fast and accurate photometric analysis program that produces comprehensive performance evaluations for non-imaging optical designs.  Photopia allows you to produce virtual luminaires in a fraction of the time and for a fraction of the cost of physical prototypes.  With computer modeling, you can test a number of design variations without altering tooling. 

New Parametric Optical Design Tools automatically produce optical designs based on your design parameters. Interactively change aiming parameters to produce your optical design in mere minutes.

Photopia provides you with several output options that allow you to characterize luminaire performance with a variety of metrics. Virtual photometry (IESNA, TM-14, and EULUMDAT) is available at the press of a button.

Photopia includes a built-in CAD system that allows you to create and manipulate components of your model. Photopia also interfaces with almost any CAD package - including: AutoCAD™, Pro/Engineer™, Solid Edge™, SolidWorks™, and SDRC™.

With all these features, it's no wonder Photopia is the most widely used optical design and analysis software at lighting companies all over the world, including those that represent over 70% of the lighting products sold in the US every year.
