- ThinLensCCDArray.spectral_rays#
The number of smaller sub-spectrum rays the full spectrum will be divided into.
This setting is important for scenes with dispersive elements such as glass prisms. This setting allows the parent spectrum to be divided into N smaller sub-regions that will be individually sampled. This allows rays with different active wavelength ranges to take different paths when passing through materials wit different refractive indexes.
Note that the number of spectral rays cannot be greater than the number of spectral bins.
