In R&D applications, one of the main limitations of the most common thermal cameras (with microbolometer sensor) is that there is a limit to the frequency of image acquisition, in the higher models being in the order of 100 - 120 images per second, in full frame. This speed may not be sufficient for some applications. In these cases, the new LWIR SLS detectors offer, at a more competitive price, shorter integration times and a wider temperature range than the Indium Antimonide (InSb) and Mercury Cadmium Telluride (MCT) detectors.
