A window structure includes a first window layer including a zinc sulfide substrate coated on each side with an antireflective coating, and a second window layer including a sapphire substrate coated on each side with an antireflective coating. The two window layers are bonded together in a facing-but-spaced-apart relation by an infrared-transparent adhesive layer, preferably a silicone rubber. The window is placed into the wall of a sensor housing that contains an infrared sensor. |
