Abstract
An optical system for performing scattering and absorbance assays in clinical diagnostics comprises a light source for emitting collimated light parallel to an optical axis in an optical path, a sample holding unit comprising at least one sample holding position located in the optical path and an optical detector for measuring light transmitted through a sample located in a sample holding position. The optical system further comprises an adjustable light angle selector adjusted to prevent light transmitted through the sample and diverging from the optical axis with an angle greater than a certain value from reaching the detector when a scattering assay is performed, and wherein the light angle selector is adjusted to allow light transmitted through the sample and diverging from the optical axis with an angle smaller than a certain value to reach the detector when an absorbance assay is performed.
