InfraTec GmbH Infrarotsensorik und Messtechnik’s ImageIR series infrared cameras have cooled focal-plane-array photon detectors of various types (indium antimonide, mercury cadmium telluride, quantum-well infrared photo-detector) and 320 x 256- or 640 x 512-pixel formats working in snapshot mode. The rugged cameras operate at frame rates of up to 4500 Hz and capture temperature differences of <20 mK. The thermography systems are designed for applications in research and development, nondestructive materials testing and process control. A range of interchangeable precise radiometric infrared lenses includes telephoto, standard, wide-angle, macroscope and microscope types. The field of view can be adjusted according to the application.
