Title: Sjoerd Antonius Maria Mentink: Innovator in Particle-Optical Devices
Introduction
Sjoerd Antonius Maria Mentink is a notable inventor based in Eindhoven, Netherlands. He has made significant contributions to the field of particle-optical devices, holding 2 patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is a method for determining lens errors in a particle-optical device. This invention focuses on a method for identifying lens errors in a Scanning Electron Microscope. It describes the use of cubic MgO crystals, which are relatively easy to produce as 'self-assembling' crystals on a silicon wafer. These crystals possess nearly ideal angles and edges, allowing for a clear representation of the beam's cross-section even in the presence of lens errors. This method enables effective reconstruction of the beam's cross-section in various focus planes, facilitating the correction of lens errors through a corrector.
Another significant patent is an apparatus for evacuating a sample. This invention involves placing a sample in a cavity of a sheet with a smooth surface. A sole plate is positioned on this smooth surface, creating a vacuum seal. The sole plate, equipped with a vacuum column, can be slid across the smooth surface to evacuate the cavity in multiple steps. In one embodiment, the vacuum column is designed as an Environmental Scanning Electron Microscope (ESEM), allowing for the inspection of the evacuated sample.
