Observation of color image using near-field optical microscope

A color image was observed using a near-field optical microscope with a He-Cd laser that lases in three primary colors. A Cu-phthalocyanine film was perceived to be blue in the image, and its actual color was almost exactly reproduced in the image. Additionally, a white particle speculated to be a d...

Description
Summary:A color image was observed using a near-field optical microscope with a He-Cd laser that lases in three primary colors. A Cu-phthalocyanine film was perceived to be blue in the image, and its actual color was almost exactly reproduced in the image. Additionally, a white particle speculated to be a dust particle was observed in the image and discerned from the film by color. The microscopically measured transmittance for each color agreed well with the spectrum macroscopically measured by a conventional spectrometer.
