THE problem of correcting the aberrations inherent in electron lenses is of major importance particularly in the field of the electron microscope, where they set a limit to the resolving power. It ...

AN article by K. Spangenberg and L. M. Field (Elec. Comm., 21, No. 3; 1943) describes and discusses the measured characteristics of a number of electrostatic lenses, giving the characteristic ...

Apple's electrostatic lens patent was first filed for in September 2014 and credits Jean-Marie Bussat as its inventor. Follow AppleInsider on Google News. 29 Comments ...

The Gemini column features a new optical design with a sophisticated lens design and gun mode. The Gemini objective lens has been further improved by optimizing geometry, and magnetic and ...

The electrostatic lens used in the new SEM still contains imperfections that will limit the microscope’s resolution, says Eastham, but the effect should be much smaller.

Electrostatic adsorption is an important complement to mechanical filtration for high-efficiency air filtering in the use of face masks. However, the electrostatic charge of the filters decays ...
