Ex 21: Starting from a blank file, the non-sequential sample file …\Samples\Non-sequential\Phosphors and Fluorescence\White LED Phosphor.zos is created from scratch. All necessary objects including sources, STEP files, lenses and detectors, are inserted. Both a scatter profile and photoluminescence are applied to the lens while all appropriate files are set for the volume physics model. A (lengthy) ray trace is run and the percent completion is displayed. Two detector viewers are opened to show the irradiance and the radiant intensity.
