Optical Design Software For SOLIDWORKS and Rhino
About Photopia Photopia is optic design software used by optical engineers to virtually prototype the performance of non-imaging optical systems before building physical prototypes. Photopia’s monte-carlo raytracing engine works inside of Solidworks or Rhino and is compatible with Inventor, Fusion, Catia, Creo, Pro/E and many other CAD softwares. https://www.ltioptics.com/
About LTI Optics LTI Optics is the company that creates and sells Photopia optical design software. We are a small company located in Westminster Colorado supporting our software around the entire globe. Members of our team have been working on Photopia and its predecessor since the 1990’s, continually improving and refining our raytracing and optical design engines. https://www.ltioptics.com/

Custom Built HDR Imaging Based BSDF Measurement Device Scatter Distributions Projected onto a Hemisphere Transmitted data (BTDF). An additional screen position can cover more of the hemisphere when the light source is below the table. Reflected data (BRDF). Some of the hemisphere needs to be filled in from surrounding data due to the gap required to let the light source illuminate the sample.
