Thermal imaging is a method of improving visibility of objects in a dark environment by detecting the objects' infrared radiation and creating an image based on that information. Thermal imaging works in environments without any ambient light and can penetrate obscurants such as smoke, fog and haze. All objects emit infrared energy (heat) as a function of their temperature - the hotter an object is, the more radiation it emits. A thermal imager can detect tiny differences in temperature, collect the infrared radiation from objects in the scene and create an electronic image based on information about the temperature differences.
Thermal images are normally grayscale in nature: black objects are cold, white objects are hot and the depth of gray indicates variations between the two. Our devices, however, have a variety of coloured polarity modes to help users identify objects at different temperatures. We offer thermal imaging hand-held monoculars for short, medium and long-range observation, medium and long-range binoculars, goggles, weapon sights for a variety of weapons, and easy-to-use clip-on systems.
