WINDOW WITH A LENS FOR AN AIRCRAFT DOOR |
摘要 |
A window for an aircraft door includes an outer pane, an inner pane, and a Fresnel lens element provided in the interspace formed between the inner and outer panes. The Fresnel lens element may be a self-supporting lens element pane positioned intermediately within the interspace between the inner and outer panes, or a lens film adhesively bonded onto the surface of the inner pane facing the interspace, or a Fresnel lens configuration provided directly on the surface of the inner pane facing the interspace. The Fresnel lens element provides an expanded field of view, especially in a downward direction, when looking out through the window, to comply with safety regulations that re- quire visual inspection of the area outside of the aircraft door and especially below the door, before opening the door.
