WebFigure 3. The optical design of the microplate photometer heavily influences OD measurements. Detector collection window size and distance from the sample change the resulting OD values, and therefore different photometers will give different ODs with the same sample. The detected OD difference can easily be 20–40%. WebSpectrophotometer Principle. The spectrophotometer is an instrument which measures the amount of light that a sample absorbs.
