The FLIR A6750 SLS longwave camera is the ideal choice for high-speed thermal events and fast moving targets. It offers extremely short integration times and windowed frame rates above 4,000 Hz, so you can freeze motion or achieve accurate temperature measurements on moving subjects. The 327,680 (640 x 512) pixel IR resolution and high sensitivity produce crisp imagery, well suited to electronics inspections, scientific research, and more.

  • Fast Integration Times

    FLIR A6750 SLS capture all pixels from a scene simultaneously in under 190 µs with full frame-rates of 125 Hz—both crucial to imaging fast-moving objects.

  • Standard Video Interfaces

    Gigabit Ethernet and analog video are simultaneously active yet independently controlled allowing greater flexibility for recording and display purposes.

  • Custom Cold Filters

    Add custom cold filters for spectral detection to image through glass, measure the temperature of thin film plastics, and more.

Connectivity and Compatibility

Connectivity and Compatibility

The FLIR A6750 SLS is plug-and-play with third-party software, and works seamlessly with FLIR ResearchIR for intuitive viewing, recording, and advanced processing of thermal data. Use the optional SDK for integration into your own custom software program.
