Abstract

Confocal fluorescence ratiometric imaging is an optical technique used to measure a variety of important biological parameters. A small amount of chromatic aberration in the microscope system can introduce a variation in the signal ratio dependent on the fluorophore concentration gradient along the optical axis and lead to bias in the measurement. We present a theoretical model of this effect. Experimental results and simulations clearly demonstrate that this error can be significant and should not be ignored.
