The ThermoCam LC (TCLC) from EVT Eye Vision Technology (Karlsruhe, Germany) detects surface defects such as cracks, pores, stripes, dents, and corrosion. The infrared camera detects corrosion that is invisible under the surface using the Impuls-Thermography method. The TCLC recognizes the defects as “hot spots.” A flash heats the surface, and the camera records the cooling of the material. Up to 100 images per second are delivered. The camera features noise (NETD) of 0.2 K, a measurement range from -50 to +300 °C, a field of view of 32 x 8 pixels, and opening angle of 40, 60, or 120°.
