Non-Destructive Testing of Advanced Materials by FLIR Systems

March 21, 2019

The FLIR A6750 SLS incorporates a cooled Strained Layer Superlattice (SLS) detector that operates in the 7.5 to 10.5 μm waveband, to produce crisp, 640 x 512 pixel thermal imagery. Record high-speed data at up to 4.1 kHz with windowing, and synchronize with other instruments to ensure you never miss any data.

Capture high-sensitivity images of fast moving objects

The FLIR A6750 SLS is a true plug-and-play thermal imaging camera, with a standard GigE Vision® interface to transmit full dynamic range digital video and GenICam for camera control. Additional interfaces include a BNC analog video output. The Gigabit Ethernet and analog video are simultaneously active yet independently controlled, allowing greater flexibility for recording and display purposes.


“Plug and play” thermal imaging reduces set-up time

The FLIR A6750 SLS captures all pixels simultaneously in under 190 μs for room temperature scenes. This is particularly important when monitoring fast moving objects where an uncooled thermal imaging camera would suffer from image blur. The camera supports image frame rates up to 4.1 kHz when operating in windowing mode.

Various software options allow custom image analysis and processsing

The FLIR A6750 SLS camera works seamlessly with FLIR ResearchIR Max software enabling intuitive viewing, recording, and advanced processing of the thermal data provided by the camera. A Software Developers Kit (SDK) is optionally available. Control the A6750 SLS and capture data directly into MathWorks® MATLAB software for custom image analysis and enhancement.
