GSENSE1517BSI

16.8MP 15 μm SCIENTIFIC CMOS IMAGE SENSOR

GSENSE1517BSI is a 4116 x 4100 (16.8 MP) resolution scientific image sensor with high-performance 15 x 15 μm2 pixels, a large 61.74 x 61.50 mm imaging area, peak QE of 92% and minimum read noise 1.2 e‾. GSENSE1517BSI fills a gap in available high-performance scientific image sensors by offering a new, larger pixel size in the popular 60 mm square format. Applications for this image sensor include astronomy imaging tasks like space situational awareness (SSA), orbital object tracking, other space-related imaging, and physical sciences research. The sensor utilizes dual-gain HDR and both 12-bit and 14-bit ADCs to achieve a variety of imaging modes. Both 12-bit HDR and 14-bit STD are supported at up to 4 fps utilizing 10 pairs of LVDS working at 420 Mbps each. In 12-bit dual-gain HDR mode, an intra-scene dynamic range over 95.3 dB is achieved with 70 ke‾ full well capacity and 1.2 e‾ readout noise. In 14-bit STD mode, either the LG or HG signal can be utilized. Using the HG signal, read noise is 1.5 e‾ and a dynamic range of 79.6 dB is achieved. Using the LG signal, the maximum full well capacity of 70 ke‾ provides an SNR up to 48.5dB. GSENSE1517BSI is assembled in a high-end SiC package designed such that the dead space at 3x package sides is minimized for mosaic tiling. The thermal expansion of SiC is close to that of the silicon die, providing mechanical stability over the sensor’s full operating range from -60 ℃ to 50 ℃. The sensor’s 144-pin Al2O3 IPGA ceramic package is offered with removable cover glass for easy assembly into cooled camera systems.
