Abstract

It is sometimes desirable to disguise infrared transmitting windows. Since these windows typically are made of exotic materials such as germanium, silicon, orzinc selenide, and often have adistinctive anti-reflection coating on them, they can tip off a knowledgeable observer about the operating spectrum of the equipment. They can also attract attention to a high-tech device, as in covert surveillance gear or in IR thermometers that measure bearing temperatures of railroad cars as they pass. In these applications, a high-tech looking window could invite theft or vandalism of the device.
