Title: Martin Oral and Magnetic Lens Innovation

Introduction

Martin Oral is an inventor associated with Brno, Czech Republic, and Fei Company. His patent work concerns magnetic lenses and charged-particle microscopy.

Latest Patents

Oral is associated with one patent, 1 patent, titled “Magnetic Lenses, Charged Particle Microscope Systems Including the Same, and Associated Methods.” The invention describes a magnetic lens that directs a charged-particle beam toward a sample location using multiple pole pieces and at least two independent coils. It can operate as an objective lens with a variable main objective plane, allowing magnification at the focal plane to be adjusted without immersing the sample in the magnetic fields produced by the coils.

The patent also describes a charged-particle microscope system comprising a charged-particle source, a sample holder, and a magnetic objective lens. Its associated method involves positioning a sample relative to the lens and operating the lens to focus the beam at a selected location.

Career Highlights

Oral’s listed patent reflects work on magnetic lens design and charged-particle microscope systems. The described approach focuses on controlling beam magnification and the objective plane while keeping the sample outside the coils’ magnetic fields.

Collaborations

Oral is listed as a coworker of Tomáš Radlička. The supplied information also associates him with Fei Company.

Conclusion

Martin Oral’s patent work centers on magnetic lenses for charged-particle microscopy, with an emphasis on adjustable focusing and magnification without immersing the sample in the coils’ magnetic fields.
