QHY367C PRO is the improved version of QHY367C. We redesigned the CMOS sensor structure and use 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 update.
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:
