Estimation of flattening coefficient for absorption and circular dichroism using simulation [PDF]
, 2009 The absorbance and circular dichroism (CD) of suspensions is lower than if the same amount of chromophore were uniformly distributed throughout the medium. Several mathematical treatments of this absorption flattening phenomenon have been presented using

Cell differentiation based on absorption and scattering. [PDF]
Journal of Histochemistry & Cytochemistry, 1979 Improvements of the flow system allow calibrated cell length measurements down to less than 2 micron at a very high rate. An optical index match to plane viewing windows perpendicular to the optical axis in the flow system keeps the axial symmetry for forward scattered light.
