27 May 2021 Share: Solid-state technology capable of imaging individual photons of light to enable full-speed photon counting at room temperature is now accessible commercially. The CMOS-based QIS devices use patented sensor architecture and pixel design to achieve record low noise that enables accurate detection of individual photons of light. Gigajot Technology, inventors of the Quanta Image Sensor (QIS), today announced the first commercially available QIS products. Photon counting and reliable photon number resolving, until now, only partially available using esoteric EMCCD technology in highly controlled laboratory environments, is now possible with a compact form-factor camera, operating at room temperature - with the additional benefits of higher resolution and speed.
