Ball Lens
A ball lens is a spherical optical component designed to focus or diverge light uniformly in all directions. Its compact form and high numerical aperture (NA) provide excellent light collection, beam shaping and optical coupling. Ball lenses are important in modern applications such as fiber communications, micro-optics, biomedical imaging and quantum optics, where precision, miniaturization and efficiency are critical.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift.
