About

LTI Optics produces the Photopia optical design software and provides optical design consulting services. Photopia is a probabilistic non-sequential raytracing program running inside of SOLIDWORKS & Rhino for designing and analyzing non-imaging optical systems for illumination, UV disinfection & curing, light pipes, IR optical sensors, signaling devices, solar concentration, daylighting, etc. Photopia includes a library of light sources based on their physical geometry, radiant & spectral properties. Photopia also includes a library of material data based on both defined optical parameters as well as measured directional reflectance/transmittance data and BSDF scattering data. LTI Optics maintains an optics lab for measuring light source and material properties from 200-1100nm.
