    Abstract: The transparent window is suitable for use in applications that require a host of very demanding performance criteria. In the window, a transparent polymer is chemically bonded to an adhesive at an interface between the two, which enables the window to resist delamination. The window also has a polymer or plastic strike face with a coating that enables it to endure rigorous field conditions and still pass critical rock strike tests. The window also has a bulk layer with at least one layer of a glass, glass-ceramic, or transparent ceramic material.
