Featuring manual motorized focus, active sensor cooling, and fast frame rates, this high-performance MWIR automation camera measures a temperature range of -4 to 662°F (-20 to 350°C), 3 to 5 μm spectral range with a 640 × 512 resolution. Moreover, it supports GigE Vision and GenICam for easy system integration and is ideal for applications where remote focus and controllable spectral/ND filtering is required.

Modern manufacturing demands thermal inspection that can keep pace with production—without frequent service interruptions. The Flir high-speed MWIR performance is designed specifically for 24/7 automation, enabling manufacturers to capture critical thermal events and maintain consistent quality on fast-moving lines. With long-life cooled technology, automation-ready interfaces, and flexible optics and calibration options, these cameras are built to operate reliably over time. The result is a cooled MWIR solution that fits naturally into production environments, reduces operational risk, and supports confident, long-term deployment.
Better process control, better product results.
The Flir A6450-Series enables tighter process control by delivering high-speed, high-sensitivity MWIR thermal data exactly when it matters. By capturing subtle temperature variations on fast-moving products, it helps identify process drift, incomplete heating or cooling, and other early indicators of quality issues. With continuous monitoring and automation-ready integration, the A6451 allows teams to intervene sooner, reduce variability, and produce more consistent, reliable results without slowing production.
Catch problems before they pass
With a 125 Hz frame rate, the Flir A6450-Series captures thermal data at production speed, enabling automated systems to detect brief temperature anomalies that occur between cycles or on fast-moving products. By seeing more frames per second the A6451 and A6481 can identify and flag issues the moment they appear—helping ensure defects are caught before they escalate.
Built for speed, designed to last
Built to perform in demanding automation environments, the Flir A6451 combines high-speed MWIR imaging with a 27,000-hour long-life cooler and a revolutionary HOT MWIR detector designed for continuous operation. This design delivers reliable performance over years of use while reducing maintenance concerns and sustaining the speed and sensitivity required for timing-critical inspection. The result is a cooled MWIR camera engineered not just to perform today, but to keep delivering day after day, year after year.
