Abstract
This optical near-field scanning microscope comprises an "objective" (aperture) attached to the conventional vertical adjustment appliance and consisting of an optically transparent crystal having a metal coating with an aperture at its tip with a diameter of less than one wavelength of the light used for illuminating the object. Connected to the aperture-far end of the "objective" is a photodetector via an optical filter and an optical fiber glass cable. Scanning the object is done by appropriately moving the support along x/y-coordinates. The resolution obtainable with this microscope is about 10 times that of state-of-the-art microscopes.

Apertureless near field optical microscopy

TL;DR: In this paper, a dither motion is applied to the tip at a first frequency in a direction substantially normal (22) to the plane of the sample surface (18), and then at a second frequency the motion is simultaneously applied to a sample (20) at a parallel direction (24) parallel to the surface plane (18) to reduce the detected background signal.

Laser beam scanning system

TL;DR: In this article, a laser beam scanning system for focusing a single laser beam to a fine spot and for scanning precisely a large field is described, where an acousto-optical deflector is used to deflect the laser beam in the direction of one axis or in the directions of two axes, while maintaining the fine spot diameter.

Optical instrument employing a truncated prism having its distal end disposed proximate a planar end of an opaque tubular housing

TL;DR: An optical instrument for examining the internal wall of an aperture in a work material comprising a generally tubular housing formed from a material that is opaque to light and having a central axis and first and second ends, the first end having an annular surface that lies in a plane substantially normal to the central axis, a light directing member formed from an elongated frustum of a right rectangular pyramid, the member having a longitudinal axis that is coincident with the center axis, and a pair of lenses mounted within the housing between the fourth end and the second end for focusing and magnifying an image

Quadrant conical-lens microscope

John E. Clegg
TL;DR: The disclosure as mentioned in this paper is a microscope in which magnification is produced by multiple quadrant stages of conical lenses, and the rays emitted by the conical lens do not converge and cross as they do with the spherical lens, and there is no inverting of images.
