Germanium Optical Lens
Germanium(Ge) is a core mid-IR crystal with very high transmission, high refractive index, and excellent thermomechanical stability over 2–14μm. It serves thermal imaging, medical IR diagnosis, lasers, security detection, and industrial thermometry. Scysgx uses high-purity single-crystal germanium substrates, more than 260 precision-processing machines, and 65 specialist inspection instruments for closed-loop cutting, grinding, polishing, coating, and inspection. plano-convex, biconvex, plano-concave, meniscus, focusing, and collimating lenses span 1–500mm, with surface accuracy up toλ/10. It provides stable, reliable lenses for high-precision mid-IR optical paths.

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.
