1. A system comprising:
at least one light source configured to generate a light at wavelengths and project the light over an optical path;
a sample device, the sample device configured to receive a sample, the sample device being transparent and being at least partially within the optical path;
a diversifier including occlusions for scattering light received from the light source along the optical path;
a first detector configured to receive the light over the optical path and from at least a portion of the diversifier, the detector configured to detect spectral intensities of the light; and
a second detector configured to receive at least a portion of the light from the optical path before the light passes through the diversifier, the second detector configured to detect spectral intensities of the light.
