Half ball lens
For high-quality half-ball lenses, Shengjinling Optics sources glass from manufacturers including SCHOTT, OHARA and SUMITA, whose strict control of nd and vd supports consistent quality. Its optical ball/half-ball lenses maintain excellent quality at diameters from 0.25mm to 10.0mm, using glasses with refractive indices from 1.40 to 2.10. Surface quality can reach 20/10 and Ra1.2nm, depending on the application. The source also describes glass ball lenses as free from scratches and pits under 30x magnification.

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.
