FLIR A6750sc SLS, A6700sc & A6750sc MWIR Cameras

Designed for electronics inspections, medical thermography, manufacturing monitoring, and non-destructive testing, the camera is ideal for high-speed thermal events and fast-moving targets. Short exposure times allow users to freeze motion and achieve accurate temperature measurements. In fact, the camera’s image output can be windowed to increase frame rates to 480 frames per second to accurately characterize even higher speed thermal events, helping ensure critical data doesn’t get missed during testing.

A6750sc cameras stream temperature-calibrated data over Gigabit Ethernet to a PC for live image viewing and recording. Using FLIR’s ResearchIR software, researchers and scientists can easily monitor, acquire, analyze, and share data. In addition, extender rings for zoomed-in fields of view make the camera perfect for imaging small thermal targets, and close-up lenses can detect spot sizes down to 15um per pixel – well beyond the capabilities that lower performance IR cameras are able to achieve.
