Gigajot unveils first commercially available quanta image sensors Date Announced: 19 May 2021 0.19e- read noise enables photon counting cameras at room temperature. Pasadena, CA, USA -- Gigajot Technology, developer of the Quanta Image Sensor (QIS), has announced the first QIS products, marking the dawn of a new era in solid-state imaging. The CMOS-based QIS devices utilize Gigajot's patented sensor architecture and pixel design to achieve record low noise that enables accurate detection of individual photons of light. The new QIS products are capable of photon counting at room temperature while operating at full speed, and achieving high dynamic range – all in small pixel, high resolution formats. With 5-10x read noise improvement over conventional small pixel image sensors, QIS enables imaging at ultra-low light levels not previously possible.
