Gigajot Technology has expanded its QIS product portfolio with the inbtroduction of the GJ04122 sensor and associated QIS41 camera. With low read noise, the GJ04122 sensor is capable of photon counting and photon number resolving at room temperature. The QIS41 camera, built around the GJ04122 sensor, pairs well with standard 4/3-inch microscopy optics, bringing unparalleled resolution and low light performance to scientific and industrial imaging applications.
The 41 Megapixel GJ04122 sensor, which was funded in part by the National Science Foundation SBIR Program, utilises a 2.2-micron pixel and has a read noise of only 0.35 electrons, which is significantly lower than state-of-the-art pixels of similar size. The QIS41 is a fully featured scientific camera based on the GJ04122 sensor. The QIS41 camera has a SuperSpeed USB 3.0 interface and is capable of true photon counting at room temperature.
The sensor is capable of photon counting and photon number resolving up to its top speed of 30 frames per second at full resolution. The high resolution and the extremely low read noise provide flexibility for binning and additional post-processing, while maintaining a read noise that is still lower than native lower resolution sensors. While pushing the limits of low light imaging, the GJ04122 sensor also offers an impressive single-exposure dynamic range of 95 dB by utilising Gigajot's patented high dynamic range pixel.
