QHY50GX Large Area Cooled Research CCD Cameras
The QHY50GX is large area liquid cooled CCD cameras intended for professional observatory use, or installations on large, long focal length optical systems. The QHY50GX is a 50.1 Mp array that is 49.1 x 36.8mm (61mm diagonal) with 8176 × 6132 pixels at 6um. The camera has round bodies and are water cooled to avoid fan vibration and to prevent air turbulence in the optical path. The camera has a GigaE interface with 100 meter data transfer capability and industry level high data transfer stability.
The QHY50GX uses On Semiconductor (Kodak) KAF−50100 Image Sensor, a high performance, 50- megapixel CCD. Based on the TRUESENSE 6.0 micron Full Frame CCD Platform, the sensor features ultra-high resolution, broad dynamic range, and a four-output architecture. A lateral overflow drain suppresses image blooming, while an integrated Pulse Flush Gate clears residual charge on the sensor with a single electrical pulse. A Fast Dump Gate can be used to selectively remove a line of charge to facilitate partial image readout. The sensor also utilizes the TRUESENSE Transparent Gate Electrode to improve sensitivity compared to the use of a standard front side illuminated polysilicon electrode.
LAMOST, the largest optical observatory in China currently uses four QHY45GX cameras
