APEX now has support for polychromatic sources. Multiple wavelengths can be added to Grid, Emitting Disk, Emitting Object and Emitting Data sources. Simply right click on the appropriate node in the Optics Manager and select "Multi-wavelength" to access the new polychromatic source features. Define blackbody, CIE, function-based, and tabular-data-based sources. Define flux, number of wavelengths, wavelength range, and randomize rays across a user-defined range of angles.
