Instead of the electrostatic and magnetic fields employed in conventional electron lenses, they utilized a light field electron-lens. Skip to main content Your source for the latest research news ...

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 ...

Fresnel lenses, however, don’t require curvature of any kind, but instead utilize concentric flat rings to diffract light, with the rings’ size and width determining the overall lens focal length.

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 ...

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 ...

At today's WWDC 2025 keynote event, Apple unveiled a new design that will inform the next decade of iOS, iPadOS, and macOS development, so needless to say, it was a busy day.

Scientists have captured the first ever photo of an electron’s whizzing orbit within a hydrogen atom, thanks to a unique new microscopy technique. Seeing inside the tiniest bits of matter is a ...

Apple's patent makes use of electrostatic lenses, made up of patterned conductive layers, to offset the displacement caused by gaps between the finger and the sensor.

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.

What that means is that the electrostatic lens would be able to read a fingerprint through different components of the smartphone — such as the display, according to a report from AppleInsider.

The innovation uses an electrostatic lens that connects the screen and sensors, allowing the device to accurately read fingerprints on the screen. Depending on the position of these lenses, ...
