They are often used to protect optical systems and electronic sensors from an outside environment. Because windows introduce no optical power into a system, windows should be selected based on the material transmission properties, optical surface specifications, and the mechanical properties that match your application. Material Properties Material properties including the transmission, refractive index, and hardness of the window substrate can be critical for deciding which window is the best choice for your application. The figure below highlights the transmission regions of the different materials Yutai Optics offers as windows.
