SLS Detectors Take LWIR Cameras to a New Level

The Advantages of LWIR Strained Layer Superlattice Thermal Cameras

FLIR_imageOnline –This new type of detector material brings FLIR’s thermal camera performance in line with their read-out integrated circuit (ROIC) and camera electronic counterparts.
The integration of Strained Layer Superlattice (SLS) detectors into commercially available thermal cameras offers a new LWIR solution with significant improvements in speed, temperature range, uniformity, and stability that costs less than analogous detector materials.
In a new online article The Advantages of Longwave Infrared Strained Layer Superlattice Thermal Cameras”, FLIR’s tech staff point out:

“While SLS works in both the longwave and midwave infrared bands, you will see the biggest performance benefits when it is filtered to the LWIR band exclusively. In fact, one of the key benefits of SLS is its short integration times, or snapshot speeds, compared with other infrared camera materials.”
“A second benefit of LWIR SLS thermal cameras is their wider temperature bands.”
“One of the best features of LWIR SLS cameras in comparison to other LWIR cooled camera options is the dramatically improved uniformity and stability through cool downs, especially when compared to LWIR MCT cameras.”
