Electron microscopes or AFMs are normally used in the observation of substances at nanoscales, but the mechanisms on which they are based do not allow for the visualization of color.
Using a near-field optical microscope allows observation of the shape, as well as the color of substances in an estimated area of 10 to 100 microns squared.
It has a pulse laser system that continues turning on and off in rapid succession, allowing the observation of (the progress of) changes in the shape of substances (e.g., the surface of pigments used in Blu-ray Disks or dye sensitized solar cells).
The wavelengths of the light used in observation can be changed to those of visible to near infrared light. This enables observation in accordance with the target.
