20100171037 | COMPACT SCANNING ELECTRON MICROSCOPE - A compact electron microscope uses a removable sample holder having walls that form a part of the vacuum region in which the sample resides. By using the removable sample holder to contain the vacuum, the volume of air requiring evacuation before imaging is greatly reduced and the microscope can be evacuated rapidly. In a preferred embodiment, a sliding vacuum seal allows the sample holder to be positioned under the electron column, and the sample holder is first passed under a vacuum buffer to remove air in the sample holder. | 07-08-2010 |
20100194874 | User Interface for an Electron Microscope - A user interface for operation of a scanning electron microscope device that combines lower magnification reference images and higher magnification images on the same screen to make it easier for a user who is not used to the high magnification of electron microscopes to readily determine where on the sample an image is being obtained and to understand the relationship between that image and the rest of the sample. Additionally, other screens, such as, for example, an archive screen and a settings screen allow the user to compare saved images and adjust the settings of the system, respectively. | 08-05-2010 |
20100230590 | Compact Scanning Electron Microscope - A compact electron microscope is robust, simple to operate, and preferably requires no special utilities.

20110315876 | Blocking Member for Use in the Diffraction Plane of a TEM - The invention relates to a blocking member to be placed in the diffraction plane of a TEM. It resembles the knife edge used for single sideband imaging, but blocks only electrons deflected over a small angle. As a result the Contrast Transfer Function of the TEM according to this invention will equal that of a single sideband microscope at low frequencies and that of a normal microscope for high frequencies. Preferable the highest frequency blocked by the blocking member is such that a microscope without the blocking member would show a CTF of 0.5. | 12-29-2011 |

20120199756 | Method for Centering an Optical Element in a TEM Comprising a Contrast Enhancing Element - A method for adjusting or aligning one or more optical elements in a Transmission Electron Microscope (TEM) is disclosed. The TEM is equipped with an objective lens for guiding a beam of electrons to a sample, a diffraction plane in which at least a beam of unscattered electrons is focused and a structure to enhance the Contrast Transfer Function (CTF) which is situated in the diffraction plane or an image thereof. | 08-09-2012 |
20130313428 | Phase Plate for a TEM - A phase plate, specifically a Zernike type phase plate, for use in an electron microscope, comprises a central hole, and a thin film causing a phase shift of the electrons passing through said film. This phase shift causes the Contrast Transfer Function (CTF) to change from a sine-like function to a cosine-like function. | 11-28-2013 |
20140061463 | IMAGING A SAMPLE IN A TEM EQUIPPED WITH A PHASE PLATE - The invention relates to a method of forming an image of a sample in a transmission electron microscope equipped with a phase plate. Prior art use of such a phase plate can introduce artifacts in the form of ringing and a halo. These artifacts are caused by the abrupt changes in the Fourier domain due to the sharp edges of the phase plate in the diffraction plane. By moving the phase plate with respect to the non-diffraction beam (the diffraction pattern) while recording an image the sudden transition in the Fourier domain is changed to a more gradual transition, resulting in less artifacts. | 03-06-2014 |
20140203191 | Method of Observing Samples with a Fluorescent Microscope - The invention relates to a method of inspecting parts of a sample on a TEM grid with a fluorescence microscope, as arises when performing correlative microscopy, more specifically for samples on a holey carbon grid. A problem occurs when imaging vitrified ice with sample material when the ice is heated by the light used. The invention is based on the insight that the absorption in the carbon support film is responsible for the heating, as ice hardly absorbs light. By localizing the illumination of the fluorescent microscope to the parts of the sample that are above a hole in the carbon, heating of the ice is lowered. The localization can be achieved by, for example, passing the light through a LCD type Spatial Light Modulator. | 07-24-2014 |
20140326876 | METHOD OF USING A PHASE PLATE IN A TRANSMISSION ELECTRON MICROSCOPE - The invention relates to a method of using a phase plate, having a thin film, in a transmission electron microscope (TEM), comprising: introducing the phase plate in the TEM; preparing the phase plate by irradiating the film with a focused electron beam; introducing a sample in the TEM; and forming an image of the sample using the prepared phase plate, wherein preparing the phase plate involves locally building up a vacuum potential resulting from a change in the electronic structure of the thin film by irradiating the phase plate with a focused beam of electrons, the vacuum potential leading to an absolute phase shift | 11-06-2014 |
20140326878 | PHASE SHIFT METHOD FOR A TEM - A method of electron microcopy passes an electron beam through a phase plate, specifically a Zernike type phase plate, comprising a central hole, and a thin film causing a phase shift of the electrons passing through said film. This phase shift causes the Contrast Transfer Function (CTF) to change from a sine-like function to a cosine-like function. The phase plate is equipped with a film in the form of an annulus, carried by a much thinner film. As a result only in a small spatial frequency range (for low frequencies) the phase is changed (and thus the CTF), and for other spatial frequencies the phase shift is negligible, and thus the CTF remains unchanged. Due to the much smaller thickness of the carrier film the scattering of electrons is negligible as well. | 11-06-2014 |
