AR-Coated Optical Window
AR-coated windows are optical windows treated to reduce surface reflection. Thin layers of materials such as magnesium fluoride or silicon dioxide are typically deposited on the window surface, gradually changing the refractive index between air and the window material to reduce reflection and improve clarity, contrast, color accuracy and light transmission.

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.
