QHY168C uses an APS-C format, 16 Megapixel, 14-bit CMOS sensor, the Sony IMX071. The SONY Exmor IMX071 sensor has 4.8um pixels and has 3.2e- read noise at lowest gain and 2.3e- read noise at unity gain (system gain = 1e/ADU), and zero amplifier glow. This sensor was used in the Nikon D5100 DSLR camera. It. The QHY168C also has a nice dynamic range close to 14 stops. With read noise this low, it is easier to detect a dim target against of the background noise.
QHY247C uses a SONY IMX193 APS size color CMOS sensor. Pixel size is 3.91um and it has a 14-bit A/D with a full well capacity of 36ke-. It has 2.7e- read noise at lowest gain, 2.2e- read noise at unity gain (system gain = 1e/ADU), and 1.0e- at high gain. It’s ideal for stacking many short exposures. The IMX193 has superb quality AR coatings on the sensor and this can significantly reduce the halo effect.
QHY128C is a full frame , 24mega pixel , one shot color cmos camera with 5.96 um pixel size and 14bit ADC. Very low dark current (0 0006e p s @ -15C) , very low readout noise (1e to 4e） and 74ke large fullwell. The QHY128C is one of the top performing cameras in the COLDMOS line. In the QHY128C this sensor is implemented specifically for astronomical use with custom thermal noise reduction technology.
QHY367C PRO is the improved version of QHY367C. QHY redesigned the CMOS sensor structure and used the Flexible Printed Circuit (FPC) to replace the previous PCB. This FPC is very small and it allows us to seal the CMOS sensor manually instead of standard reflow soldering. Besides, QHY367PRO will support the FPGA firmware upgrade via USB function. The internal FPGA code is more easy to get updated. QHY367C Pro is a full frame color cooled cmos camera with SONY IMX094 sensor. 14bit ADC, zero amplifier glow. QHY367C Pro is one of the top performing full frame camera among COLDMOS Series.The Sony Exmor IMX094 CMOS sensor is also found in the Nikon D800/810 DSLR cameras. This sensor is implemented in the QHY367C Pro specifically for astronomical use with QHYCCD thermal noise reduction technology. With read noise as low as 2.4e-, full well capacity of 56ke-, the camera has a dynamic range of more than 14 stops.
TRUE RAW Data
In the DSLR implementation there is a RAW image output, but typically it is not completely RAW. Some evidence of noise reduction and hot pixel removal is still visible on close inspection. This can have a negative effect on the image for astronomy such as the “star eater” effect. However, QHY Cameras offer TRUE RAW IMAGE OUTPUT and produces an image comprised of the original signal only, thereby maintaining the maximum flexibility for post-acquisition astronomical image processing programs and other scientific imaging applications.
Based on almost 20-year cooled camera design experience, The QHY cooled camera has implemented the fully dew control solutions. The optic window has built-in dew heater and the chamber is protected from internal humidity condensation. An electric heating board for the chamber window can prevent the formation of dew and the sensor itself is kept dry with our silicon gel tube socket design for control of humidity within the sensor chamber.
In addition to dual stage TE cooling, QHYCCD implements proprietary technology in hardware to control the dark current noise.
As a result the dark current of the camera is:
QHY168C: 0.0007e-/p/s at -15C
QHY247C: 0.0012e-/p/s at -15C
QHY128C: 0.0006e-/p/s at -15C
QHY367C Pro: 0.0015e-/p/s at -15C
