LTI Optics is your resource for optical design consulting and optical design software. Our Photopia optical design software is used to design a wide range of non-imaging optical systems for applications including illumination, UV curing & disinfection, light pipes & light guides, IR optical sensors, signaling devices, solar concentration, daylight collection & delivery, etc. Photopia includes a large library of accurate light source models and material properties, including measured BSDF data. LTI Optics maintains its own optics lab for characterizing lamp and material properties in the UV, VIS and NIR ranges. Photopia runs as an add-in inside of SOLIDWORKS and Rhino CAD software, allowing you to leverage the strengths of each program in your optical design process. Design and test performance within your complete SOLIDWORKS assembly models with all mechanical features & design limitations considered. Photopia for Rhino provides a powerful platform with fully programmable Python simulation scripts along with geometry creation and optimization with the Grasshopper visual programming language and Photopia's built in Parametric Optical Design Tools.
