Abstract

We correlated SHG and Electron Microscopies to calibrate SHG signals as a function of collagen fibril diameter, down to 30 nm. We observed a fourth power dependence, in agreement with analytical and numerical calculations. We applied this calibration to abnormal fibrils in the Descemet’s membrane of intact unfixed rat corneas.
