"Remote sensing and thermographic cameras are sensitive to longer wavelengths of infrared. They may be multispectral and use a variety of technologies which may not resemble common camera or filter designs. Cameras sensitive to far infrared including those used in infrared astronomy often require cooling, since all objects at room temperature (including the camera body, optics, and the detector itself) are glowing all the time at these wavelengths (see thermal radiation). Lower priced thermographic digital cameras extend the spectral range less far into infrared. These cameras are generally used for building inspection or preventative maintenance but can be used for artistic pursuits as well, such as this image of a cup of coffee."
