Dr. Dieter W. Pohl devised Scanning Near-Field Optical Microscopy (SNOM) with localized evanescent waves at IBM Zurich Laboratories, Switzerland in 1982, and demonstrated a super resolution image via visible light for the first time in the world. A small aperture which size was much smaller than wavelength of light, was made at the sharpened tip of dielectric material (quartz) with metal coating and non-radiation light (near-field light) generated at the aperture was used as a light spot.
