Optical Window
A basic optical-system element, it acts like a sealed window, protecting precision internal optics while passing light efficiently without distortion. It is mainly used in industrial lasers and precision optical detection and measurement equipment, including spectrometers, interferometers and other research and industrial inspection instruments. High transmission and low reflection are essential for accurate measurements.

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.
