The CMOS-based QIS devices of Gigajot Technology has a patented sensor architecture and pixel design to achieve low noise that enables accurate detection of individual photons of light. The new products are capable of photon counting at room temperature while operating at full speed, and achieving high dynamic range. With 5-10x read noise improvement over conventional small pixel image sensors, QIS enables imaging at ultra-low light levels. The 16MP GJ01611 utilizes a 1.1-micron pixel to achieve room temperature 0.19 electron read noise and less than 0.09 electron/second/pixel dark current, while the 4MP GJ00422 employs a 2.2-micron pixel and provides 0.27 electron read noise with single-exposure high dynamic range of 100dB. The QIS Camera Development Kit has a USB 3.0 interface and a software, in a small form factor.
