    Abstract: The Near-field Optical Transmission Electron Emission Microscope involves the combination, in one instrument, of optical imaging in the near-field regime or close to it (in respect to the transmission electromagnetic radiation when the wavelength exceeds the desired lateral resolution) and the secondary electron imaging of EEM microscope (“Cathode lens objective” based Emission Electron Microscopy). These two microscopic techniques are combined by the application of the photon-electron converter, which converts the optical, transmission image of the object (illuminated by the penetrating electromagnetic radiation) to the correlated photoelectron image, by means of a matrix of one-way closed channels (capillaries). The closed, smooth front face of the converter (comprising channel-bottoms) remains in contact with the object of imaging, whereas its opposite, opened face (consisting of an array (matrix) of channel openings) is exposed to vacuum and emits the secondary electrons.

    Abstract: Techniques are described that facilitate automated extraction of lamellae and attaching the lamellae to sample grids for viewing on transmission electron microscopes. Some embodiments of the invention involve the use of machine vision to determine the positions of the lamella, the probe, and/or the TEM grid to guide the attachment of the probe to the lamella and the attachment of the lamella to the TEM grid. Techniques that facilitate the use of machine vision include shaping a probe tip so that its position can be readily recognized by image recognition software. Image subtraction techniques can be used to determine the position of the lamellae attached to the probe for moving the lamella to the TEM grid for attachment. In some embodiments, reference structures are milled on the probe or on the lamella to facilitate image recognition.
