FLIR A6750sc Cooled SLS LWIR Scientific-Grade Thermal Camera

LWIR 7.5-10.5µm camera with high-resolution Strained Layer Superlattice (SLS) detector. Full resolution 125 Hz, 480ns exposure time. 

The FLIR A6750sc SLS is a high sensitivity full-resolution thermal camera 640 x 512 pixels. The affordable FLIR A6750sc SLS is the entry to cooled LWIR high performance thermal cameras, ideal for high-speed thermal events and fast-moving targets.




Scientific Cooled Camera

  • Deeply cooled SLS detector
  • Advanced triggering
  • Interchangeable filters
  • Frame rates from 125 to 4175 Hz
  • Integration times down to 480ns

The FLIR A6750sc SLS is a  full-resolution thermal camera with high sensitivity; an affordable, flexible solution for real-time thermal imaging. The FLIR A6750sc SLS is the entry to cooled LWIR high performance thermal cameras.

Two f/# versions are available with a large choice of lenses and extension rings, the A6750sc SLS is a versatile camera for all your thermal imaging needs. Cooled, SLS based thermal cameras have inherently shorter integration times for a given temperature range than their MWIR counterparts, making them ideal for high-speed thermal events and fast-moving targets.

The internal interchangeable filters makes it  easy to change either user or factory calibration ranges.
