Abstract

National Astronomical Observatory of Japan and Hamamatsu Photonics K.K. have been developing large format and high-speed readout CMOS sensors. It is designed to be 2,560 × 10,000 pixels with 7.5μm and three-side buttable in order to cover a wide field of view. The CMOS sensors is designed to be back-illuminated to achieve higher filling factor than front-illuminated CMOS sensors and to improve the sensitivity by avoiding photon absorption by the poly-silicon circuit. Each pixel row is equipped with an ADC to achieve the frame rate of 10Hz. The evaluation in the laboratory shows that the sensor has excellent performance; the quantum efficiency is 80% at maximum at 600nm and readout noise is 3 e⁻ rms at 2fps. We are developing a wide field camera using these CMOS sensors.
