Average customer time and cost savings with speos : 65 % Easiest and fastest process from design to production Our 18 years of experience in the domain of optics and information technology go to make SPEOS the best standalone tool for virtual prototyping of lighting systems. IGHT MODELING is based on advanced high speed Monte-Carlo non-sequential light propagation. Light can be split into reflected, refracted, diffracted and scattered components. Propagation takes into account optical properties for all surfaces, materials and sources emission. Results can be used to verify the compliance with International Standards and customer specification. Virtual Photometric Laboratory (VP Lab) provides a range of tools (cross section, contrast, iso-curves, spectral and chromaticity coordinates…) for analysis. Moreover, sensors simulation allows you to treat illuminance(lux), irradiance(W/m2), intensity(cd), radiant intensity(cd/sr), luminance(cd/m2) and radiance(W/m2.sr). VISUAL ERGONOMICS is based on a unique physics based approach to light. The final picture takes into account all optical properties (scattering, absorption, refraction,…) including their spectral behavior: the only way to obtain exact colors. The exact aspect of the final surface even for brushed surfaces and iridescent paints offers very realistic rendering of virtual products including lit appearance. Human vision is taken into account thanks to a very accurate physiological human vision model. COLORIMETRY allows to make colorimetric analysis of all photometric and image results : spectral/colorimetrychromaticity coordinates (xyY, Lab, Luv…) can be easily obtained.
