Abstract
A window structure includes a first window layer having a zinc sulfide substrate coated on each side with an antireflective coating, and a second window layer having a bulk silicon 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. A targeting/sensor system using the window structure includes a targeting laser and a sensor within a housing having the window structure in its wall.
