A relatively new type of photon detector material for infrared cameras offers a solution for scientists and engineers who need to record fast thermal transients or capture crisp still images of high speed objects or events. This material, called Type II Strained Layer Superlattice, or SLS, can match or exceed most of the performance of analogous detector materials such as indium antimonide (InSb) or mercury cadmium telluride (MCT). This article compares LWIR SLS detectors to MWIR InSb and LWIR MCT detectors, with specific attention to their integration times, temperature ranges, filtering needs, and uniformity.
