CVD Zinc Sulfide ZnSA001
CVD zinc sulfide has the characteristics of high purity, insoluble in water, moderate density, and easy processing. Used for the production of infrared lenses, infrared windows, fairings, and infrared optical components. In addition, CVD zinc sulfide is also an optical material with good refractive index uniformity and consistency, and has good image transmission performance in the 8μm-12μm wavelength range. It also has a high transmittance in the mid infrared band, but as the wavelength becomes shorter, absorption and scattering increase. It can process shapes such as circular, rectangular, perforated, crescent, wedge-shaped, flat convex, flat concave, double convex, double concave, open ball, and prismatic. UM OPTICS has complete optical crystal production equipment and experience, and can provide high-quality CVD zinc sulfide crystals.

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.
