DESCRIPTION:
The FLIR A6750 SLS is a research-grade cooled thermal imaging camera engineered for applications requiring high-speed thermal data acquisition and precise temperature measurement. Utilizing a cooled Strained Layer Superlattice (SLS) detector operating in the longwave infrared spectrum, the system provides exceptional image quality while capturing fast thermal transients and moving targets without motion blur.
With a 640 × 512 detector resolution and full-frame operation up to 125 Hz, the A6750 SLS supports sub-windowing modes exceeding 4,000 Hz, making it suitable for ballistics testing, materials research, electronics development, aerospace research, additive manufacturing, and industrial process monitoring. Snapshot acquisition technology captures all pixels simultaneously in less than 190 microseconds for room-temperature scenes, ensuring accurate thermal analysis of high-speed events.
The camera integrates Gigabit Ethernet connectivity for data transfer and camera control while supporting FLIR Research Studio and third-party software environments. Optional cold filters enable specialised spectral applications including imaging through glass, thin film inspection, and customised thermal analysis.
