Abstract
In spite of the very wide applications of a near-field optical microscope (NOM) in various fields such as observation of biological specimens, optical storage etc. [1,2], a systematic analysis of the images with respect to resolution and contrast is lacking. In this work using 20 nm gold particles (calibrated by electron microscope) fixed on a glass plate as the observation object, we have evaluated the transfer function of NOM.
