Optical windows are used for protecting fragile optical components inside an assembly. Windows are optical glass with ground and polished faces that are relatively parallel. They are used to isolate two physical environments while allowing light to pass. We offer N-BK7 Optical windows and Fused Silica Optical windows. In addition, we provide a variety of single layer antireflecting coating on optical windows.
