KAYA Instruments’ IMX661 camera sets a new standard in imaging with 13400(H) x 9528(V) resolution, 46.2mm x 32.9mm pixel size (3.45µm x 3.45µm), 70.8dB dynamic range, and 9825e- full well charge. It boasts a global shutter, variable shutter speeds (down to 13.35µs), and electronic shutter controls for precise image capture. Video output features include 4 channels 12G CoaXPress, delivering up to 50 Gbps data transfer. Additional capabilities include continuous or triggered image acquisition, on-camera processing (LUT, defect pixel correction), and enhanced connectivity through GPIO, making it ideal for professional photography, industrial inspection, and scientific research.

Innovative Approach – The Iron661 is a low-cost, low-power, high resolution global CMOS camera with up to 50 Gbps CoaXPress v2.0 interface (Micro-BNC connector) which supports 127 MP high quality video,  with 13400 (H) x 9528 (V) resolution, at rates of up to 22fps.

Intelligent Design – Iron661 incorporates a IMX661 global shutter sensor with 3.45µm pixel size. With a compact outline the camera can be fitted into tight spaces. Superior sensor performance allows very low light vision capabilities.
