IUC26000KPA-AFU Industrial Cameras/Analytical Imaging
Product Introduction
                                    The IUC-AFU-EF series addresses high-resolution industrial and research scenarios requiring rapid, stable focusing, featuring APS-C and full frame (35 mm) large-format CMOS sensors with resolutions ranging from 26–60 MP. Equipped with electronic EF mount, the cameras directly control Canon EF/EF-S lens autofocus and electronic aperture, significantly simplifying system integration and enhancing focusing efficiency for multi-magnification and long working distance applications.
For connectivity, the series offers USB3.0 and 10GigE (model-dependent) high-speed data interfaces, supporting multi-bit depth output and internal buffering to meet high-bandwidth and long-distance acquisition requirements. The cameras support free-running, software/hardware triggering, and multi-camera synchronization, with optically isolated I/O for trigger/strobe control and programmable GPIO, facilitating coordination with light sources, motion platforms, and other peripherals.
Complete software ecosystem includes bundled ToupView and cross-platform SDK (Windows / Linux / macOS; C/C++/C#/Python, etc.), compatible with DirectShow / TWAIN, suitable for custom development and rapid deployment of integrated systems and OEM solutions.

Featuring APS-C (1.8") and full-frame (2.7") sensors, the series delivers up to 60 MP for high-precision inspection and wide-area imaging. The 3.76 µm pixel size balances detail with low-light sensitivity, while dark current as low as 0.04 mV @ 1/30 s enables long exposures and high-contrast inspection. Selectable 8-bit, 12-bit, and 16-bit outputs support both scientific and industrial analytics.
Back-illuminated CMOS advantages
Sensors like the IMX571 and IMX455 deliver high quantum efficiency and low noise for superior performance in low-light environments. The back-illuminated design significantly boosts photon collection, enhancing signal-to-noise ratios. The cameras provide up to 6.1 fps @ 9568×6380 at 16-bit full resolution, with ROI mode enabling 191 fps @ 1040×706.
Intelligent autofocus system
Canon EF-mount autofocus streamlines tasks that require frequent focal adjustments. Compatibility with EF lenses ensures fast, precise focusing, while exposure control from 150 µs to 15 s covers high-speed capture, long-exposure imaging, and free-run, software, or hardware trigger modes.
Flexible binning and ROI modes
Supports 1×1, 2×2, 3×3, and 9×9 binning plus ROI to balance sensitivity and frame rate. USB 3.0 delivers high-speed data and power over a single cable, simplifying system wiring. Power consumption stays below 5 W, and opto-isolated I/O eases integration into existing automation architectures.
