A8481

Compact MWIR HD Science Camera

The A8481 and A8451 bring 1280 × 1024 HD MWIR imaging to the compact A-Series body, with four times the pixels of VGA A-Series cameras. They share their body and mounting points with the A6451, A6481, and A6700 Series, so existing fixtures and cabling carry over. The 8 µm high operating temperature (HOT) strained-layer superlattice (SLS) detector is cooled by a long-life linear cooler rated in the 27,000-hour class. The A8481 adds a motorized lens interface and a motorized 3-position filter wheel, and both cameras support a range of FLIR Precision Optics lenses. Gigabit Ethernet or CoaXPress connectivity provides complete camera control and fully radiometric capture in FLIR Research Studio Professional.

Product Overview

HD Without the Big-Body Tradeoff

The A8481 and A8451 bring HD thermal imaging to the compact A-Series form factor for the first time.

Delivering 1280 × 1024 resolution in the same proven body used throughout the A67xx family, the A84xx-Series gives researchers four times more pixels without changing optics, fixtures, software, or workflows.

The A8481 extends the platform further with a motorized filter wheel and lens interface, enabling automated optics control and broader temperature measurement capability.

The result is greater thermal detail, more measurement points, and faster scientific insight, all from a platform your team already knows. With HOT MWIR SLS technology, full radiometric recording, precision synchronization, and support for FLIR Precision Optics, the A84xx-Series helps engineers and researchers move beyond VGA limitations while keeping the simplicity of the A-Series ecosystem.

Why We Built It

HD Used to Mean a Bigger Camera

For years, moving from VGA thermal imaging to HD meant moving to a larger camera platform. New mounts. New cabling. New integration work. New validation cycles.

The A84xx-Series changes that.

Built around a 1280 × 1024 HD MWIR detector, the A8481 and A8451 bring HD thermal imaging into the same compact A-Series platform trusted by researchers and engineers around the world.

4× More Pixels
Capture more thermal detail across the same scene without sacrificing field of view.
Zero Re-Integration
Reuse existing fixtures, mounts, cabling, optics, and software.
Compact Design
Deploy HD imaging in space-constrained labs, test cells, and research environments.

A Natural Upgrade Path

Four Times the Pixels.
Same Workflow.

The A8481 was designed as a natural upgrade path for A-Series users.
Keep
• Existing FLIR Precision Optics
• Existing mounts and fixtures
• Existing software environment
• Existing analysis workflows
• Existing automation infrastructure
The HD array is nearly the same physical size (10.2 mm vs 9.6 mm across) - so on the same focal length you keep a comparable field of view, now sampled roughly twice as finely. Or window in and trade pixels for speed.
