The adapter enables users of Amada cutting systems with 2.0" diameter lenses to use Lens Savers® windows under high pressure. The adapter attaches to the OEM or replacement lens vendor's lens mount by means of a cylindrical connector assembly which is attached to the OEM lens mount by means of socket head cap screws. The socket head cap screws in the OEM lens mount fit into counterbores in the connector assembly.

The adapter provides a holder for Lens Savers® window which is easily removed simply by removing the socket head cap screws. The focusing lens need not be disturbed or touched when the Lens Savers® window is removed. It also allows the assist gas pressure to pass into a cavity between the Lens Savers® window and the lens, which results in the pressure on both sides of the window being equalized. ICL's patent pending pressure equalization method prevents the Lens Savers® windows from breaking by providing an environment in which the pressure around the windows is equalized.
