The QHY50GX is a cooled CCD camera with a 50 megapixel medium format 48x36mm CCD image sensor. It is mainly used by large astronomical telescopes. It has the characteristics of large effective photosensitive area, high resolution and fast image downloading speed. The pixel size is 6.0um and it has a four channel readout using four independent 16-bit high precision 8MHz A/D converters. The noise floor of the AD converter is 3-4 ADU. The QHY50GX has a round design and is ideal for large field of view primary focus imaging.
The QHY50GX has a round design and is ideal for wide field of view primary focus imaging. The water-cooling heat-dissipation method is adopted to avoid heated air dissipation and convection currents around the camera that could affect the telescope's primary focus near the entrance pupil. The water cooling system also avoids any vibration that might be generated by a cooling fan.
The KAF-50100 Image Sensor is a high performance, 50-megapixel CCD with 8208 x 6164 pixels at 6um. 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. The sensor also utilizes the TRUESENSE Transparent Gate Electrode to improve sensitivity compared to the use of a standard front side illuminated polysilicon electrode.
The QHY50GX uses a high-stability GigaE Gigabit Network interface to the computer. The transmission distance can reach 100 meters. Long-distance, anti-electromagnetic interference fiber transmission can also be achieved through Gigabit-fiber optic repeaters.
