ORCA-spark Digital CMOS camera


The ORCA-spark is a high-sensitivity digital CMOS camera using a 2.3 megapixel CMOS sensor.
It has global shutter to achieve a high-speed readout of approx. 65 frames/s, making it ideal for imaging fast moving objects.
The ORCA-spark also delivers readout noise levels as low as 6.6 electrons, enabling imaging with high S/N ratio even when capturing images of dark objects.
