High-speed infrared camera

X6981 SLS / X6901sc SLS

The FLIR X6981 SLS / X6901sc SLS is an extraordinarily fast, highly sensitive LWIR camera designed for scientists, researchers, and engineers. The strained layer superlattice (SLS) detector offers shorter snapshot speeds, wider temperature bands, and better uniformity than current LWIR or MWIR alternatives. With advanced triggering, on-camera RAM/SSD recording, and a four-position motorized filter wheel, this camera offers the functionality to stop motion on high-speed events both in the lab and at the test range.
