Advanced Cooling Technology Reduces Dark Current Down to 0.001e-/pixel/s
Based on Viewsecctv Camera Products’s professional cooling technology from sCMOS cameras, VCI-A3U2000RC-BSI can achieve a dark current level as low as 0.001e/pixel/s, which significantly reduces the hot pixel noise during long exposure time.
High SNR, Balanced with Exposure Time
Quantum efficiency and noise correspond to signal and noise. Respectively, the higher the ratio, the higher the signal-to-noise ratio. While providing high quantum efficiency of 84%, the VCI-A3U2000RC-BSI strives for excellence in noise control, reducing read noise to 0.6e- and dark current to 0.001e-/s, which makes VCI-A3U2000RC-BSI the best camera for High signal-to-noise ratio balanced with exposure time.
Red circle area: Under short-term exposure, sCMOS has the best signalto- noise ratio because of its high quantum efficiency and low readout noise.
Blue circle area: At the exposure time around above 1 second. The VCI-A3U2000RC-BSI maintains a better signal-to-noise ratio because of the combined advantages of low readout noise and dark current noise, while the SNR of sCMOS drops rapidly, because of the high dark current noise .
The Core Advantage of the VCI-A3U2000RC-BSI: the Most Comprehensive Performance
In the past decade CCD has gradually withdrawn from the scientific imaging arena. The lower-noise faster-speed sCMOS is the leader in advanced scientific imaging. However sCMOS still does not solve the problem of high dark current noise and high cost. So in applications which require long exposure time and the need for cost-effective scientific imaging, users have to continue to use very old CCD cameras. Now Viewsecctv Camera Products has introduced the VCI-A3U2000RC-BSI camera, which achieves the same level of CCD as the dark current noise and cost performance. At the same time it has the typical characteristics of CMOS: lower readout noise and faster speed. It is a camera with the most comprehensive performance.
