LightTools 9.0

New Tools to Model Polarization Elements in AR/VR Headsets and Biomedical InstrumentsLightTools 9.0 provides new tools to model and analyze polarizing elements with birefringent materials, which are increasingly used in advanced applications such as AR/VR headsets and biomedical instruments. New charts allow designers to easily assess the polarization state and orientation and identify how to maximize flux. The new polarization modeling tools are included in the LightTools Advanced Physics Module, which provides flexible programming extensions to develop custom optical parts and cutting-edge illumination subsystems.Stray Light Analysis EnhancementsLightTools has comprehensive capabilities to help optical engineers pinpoint and correct stray light issues during product design. Enhancements to the LightTools stray light analysis toolkit include:Intensified ray tracing - LightTools now traces up to one trillion rays inan illumination system, lifting the sampling limits for virtually all MonteCarlo simulations. This expanded ray trace limit allows designersto achieve extremely accurate results for stray light analysis andluminance calculations.Aim area capabilities for measured bidirectional scattering distributionfunction (BSDF) surfaces - BSDF data is often used to provide high-accuracy simulations of scattering surface characteristics. The aim areafeature allows designers to examine selected portions of a surface’sscatter distribution, and this can significantly improve stray light analysisefficiency, particularly for illumination optics used in AR/VR/MR devices,heads-up displays, and autonomous vehicles
