Patent number: 9865427Abstract: 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.Type: GrantFiled: May 5, 2015Date of Patent: January 9, 2018Assignee: FEI CompanyInventors: Martinus Petrus Maria Bierhoff, Bart Buijsse, Cornelis Sander Kooijman, Hugo Van Leeuwen, Hendrik Gezinus Tappel, Colin August Sanford, Sander Richard Marie Stoks, Steven Berger, Ben Jacobus Marie Bormans, Koen Arnoldus Wilhelmus Driessen, Johannes Antonius Hendricus W.

Patent number: 8921785Abstract: The invention relates to an assembly of a cooperating capillary and cap for containing an aqueous solution in an inner volume of the capillary. The assembly is used in a high pressure freezer in which the aqueous solution is frozen at a high pressure to form an amorphous frozen sample at a cryogenic temperature. The cap forms a closure at one end of the capillary, and the part of the cap that is in contact with the inner volume of the capillary has an indent; as a result of which the cap, after freezing the aqueous solution, can be removed from the capillary and a free standing pillar of frozen aqueous material extends from the capillary.Type: GrantFiled: September 9, 2013Date of Patent: December 30, 2014Assignee: FEI CompanyInventors: Rudolf Johannes Perer Gerardus Schampers, Johannes Antonius Hendricus W. G. Persoon, Andreas Theodorus Engelen

Patent number: 8309921Abstract: 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.Type: GrantFiled: February 1, 2011Date of Patent: November 13, 2012Assignee: FEI CompanyInventors: Martinus Petrus Maria Bierhoff, Bart Buijsse, Cornelis Sander Kooijman, Hugo Van Leeuwen, Hendrik Gezinus Tappel, Colin August Sanford, Sander Richard Marie Stoks, Steven Berger, Ben Jacobus Marie Bormans, Koen Arnoldus Wilhelmus Driessen, Johannes Antonius Hendricus W.

Publication number: 20100230590Abstract: A compact electron microscope is robust, simple to operate, and preferably requires no special utilities. Imaging can begin shortly after a sample is inserted. A preferred simplified design includes permanent magnets for focusing, lack a vacuum controller and vacuum gauge, and uses a backscattered electron detector and no secondary electron detector.Type: ApplicationFiled: June 7, 2007Publication date: September 16, 2010Applicant: FEI COMPANYInventors: Mart Petrus Maria Bierhoff, Bart Buijsse, Cornelis Sander Kooijman, Hugo Van Leeuwen, Hendrik Gezinus Tappel, Colin August Sanford, Sander Richard Marie Stoks, Steven Berger, Ben Jacobus Marie Bormans, Koen Arnoldus Wilhelmus Driessen, Johannes Antonius Hendricus W.
