Chalcogenide Glass Aspheric Lens PAsSG-
Sulfur based glass aspherical lenses are a type of non oxide glass material formed by introducing one or several elements such as Ge, As, Sb, Ga, etc., with sulfur group elements as the main component. They can be used as lens materials for infrared thermal imaging systems and are the "golden eye" of infrared temperature measurement equipment. Non spherical optical components can achieve imaging quality of spherical optical components. In optical systems, it can correct various aberrations, improve imaging quality, and enhance system identification ability. It can replace multiple spherical components with one or several non spherical components, thereby simplifying instrument structure, reducing costs, and effectively reducing instrument weight. It can be coated with MgF2, UV-AR, UV-VIS, VIS-EXT, VIS-NIR, NIR I, NIR II, Telecom NIR, SWIR, SWIR, YAG-BBAR and other film systems.

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.
