The 5.5 megapixel sCMOS sensor offers a large field of view and high resolution, without compromising read noise or frame rate. The read noise in itself is exceptional, even when compared to the highest performance CCDs. Only slow-scan CCDs are capable of this level of read noise performance. High-resolution, slow-scan CCDs are typically characterized by seconds per frame rather than frames per second (fps). The fact that the sCMOS device can achieve < 2 electrons rms readout noise while reading out 5.5 megapixels at 30 fps renders it truly extraordinary in the market. Furthermore, the sensor is capable of achieving 100 full fps with a readout noise < 3 electrons rms. By way of comparison, the lowest noise interline CCD, reading out only 1.3 megapixels at ~ 16 fps would do so with ~ 10 electrons readout noise. Greater speed is available through selection of ‘region of interest’ sub-windows, such that the field of view can be traded off to achieve extreme temporal resolution. The low noise readout is complemented by a high dynamic range of 22 000 : 1. Usually, for CCDs or emCCDs to reach their highest dynamic range values, there needs to be a significant compromise in readout speed, yet sCMOS can achieve this value while delivering 30 fps. Furthermore, the architecture of sCMOS allows for high dynamic range by offering a large well depth, despite the small pixel size. By way of comparison, a 1.3 megapixel interline with similarly small pixels achieves only ~1800:1 dynamic range at 16 fps.
