In this study, size of a highly used biological substance in medicine called sephadex is measured using the digital microscopic interferometry technique. Initially, magnification of the designed interferometer was determined using standard diffraction gratings and then the recorded size of the diffraction gratings was used as a scale for measuring the size of the sephadex specimens. Standard diffraction gratings with 100, 300 and 600 lines per millimeter were used for calibrating the digital holographic microscopy setup. Diameter of a G200 sephadex particle is estimated about 123.8 micrometers and it is shown that the measurement is consistent with a separate measurement with neobar lam technique.
