Abstract:
The object of the present invention provides a scanning transmission electron microscope with the ability to formed at least one diffraction pattern. The scanning electron microscope comprises an electron source, which is configured to provide primary electron beam, a condenser lens system, an objective electromagnetic system, a projection lens system and a detection system, in addition, the objective electromagnetic lens consists of an upper pole piece and a lower pole piece, wherein each pole piece comprises a pole piece face, which is a flat surface oriented towards a sample plane. A salient feature of the present invention is to form at least one diffraction pattern located in the distance from the lower pole piece face outside the pole piece gap, wherein the pole piece gap is the space between the upper pole piece face and the lower pole piece face.

Claim (Index 15):
A method of providing single diffraction pattern, bright field image and dark field image in a scanning transmission electron microscope comprising an electron source configured to provide a primary beam with cross-over, a condenser system, an objective electromagnetic lens comprising an upper pole piece and a lower pole piece configured to provide a pre-field and a post-field with respect to a sample plane located inside a pole piece gap, wherein the upper pole piece comprises an upper pole piece face and the lower pole piece comprises a lower pole piece face, a projection lens system and a detection system, wherein the post-field provided by the objective electromagnetic lens is comprised of single lens, wherein the single lens is formed between the sample plane and the lower pole piece face, wherein the single lens generates a virtual cross-over image in a virtual image plane and a single diffraction pattern, wherein the diffraction pattern is located in a distance from the lower pole piece face outside the pole piece gap, wherein the distance between the lower pole piece and the at least one diffraction pattern is in the interval (0-1) mm, wherein the diffraction pattern is then transferred with variable magnification by the projection lens system into the detection system.
