Once you fall deep enough into the rabbit hole of any project, specific information starts getting harder and harder to find. At some point, trusting experts becomes necessary, even if that ...

Bessel Beams are impossible to create, can’t be destroyed, and don’t diffract. In other words, physics has discovered yet another thing that makes no sense. Bessel beams bear the name of Friedrich ...

Bessel beam microscopy, and the techniques that preceded it, are generally used to image live cells in 3D. Bessel beams have a greater capability than other super-resolution imaging techniques for ...

Scientists in China have developed a metasurface platform that realizes true three-dimensional (3D) vectorial holography by ...

Last year, we looked at three potential “tractor beam” technologies being evaluated by NASA to deliver planetary or atmospheric particles to a robotic rover or orbiting spacecraft. At the time, the ...

In the good old days of analog scopes, you pretty much had only one choice for frequency response—Gaussian. That came about because of the natural way in which the behavior of multiple components with ...

LASER COMPONENTS offers Bessel lens assemblies which are used to form non-diffractive Bessel laser beams, consisting of two concentric rings of equal power. Bessel lens assemblies consist of an axicon ...

Nine Medtech Startups Spanning AI Diagnostics, Surgical Robotics, Drug Delivery, and Orthopedic Implants Featured, Five Completed Bessel’s Accelerator Program. Chris and the Bessel team are ...
