Lithium Fluoride Lens
Lithium fluoride(LiF) is a specialized optical crystal with excellent deep-UV transmission, broad IR response, very low refractive index, and high optical homogeneity across vacuum UV, deep UV, and mid-IR. Scysgx uses high-purity single-crystal substrates,260 precision-processing machines, and 65 specialist inspection instruments for full in-house development and production. Plano-convex, biconvex, plano-concave, meniscus, collimating, and focusing lenses span 1–500mm with surface accuracy up toλ/10. They provide core optics for deep-UV systems, IR detection, lasers, spectroscopy, and medical optics.

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.
