Multi-Spectral Imaging (MSI) of choroidal lesions in NF – Page 21 of 38

The blue line highlights the near Gaussian distribution of the human eye’s sensitivity to light. Traditional fundus cameras mimic this and reveal images similar to what is seen by the human eye. Blue, Red, and Green light sensors have been used in Fundus cameras. Beyond 650nm, traditional fundus imaging cameras lose sensitivity.

OCT/SLO technology utilize a single very narrow wavelength in the infrared zone that allow cross-sectional information of the retina to be obtained.
