The QHY42 BSI Class2 Cooled Cameras use the Gsense400 Scientific CMOS sensor with an extraordinary 95-percent peak QE, 79-percent UV QE, and have a very good NIR response. There is also an extremely low read noise reading of 1.7e-.

This camera is ideal for astronomical and biological science research. 



The low read noise and high QE make it possible to achieve high Signal to Noise Ratio even when imaging dim objects. Only 5 photons produce a SNR>3.


Amplifier Glow Control: Reduces Glow Significantly 
Unique QHY Technology

Amplifier glow exists in many CMOS sensors. QHYCCD has developed a unique technology to reduce it. As applied in the QHY42, the user may enable / disable this feature.


Large Pixel Size: 11 um   89ke- Full Well Capacity:

The QHY42 has relatively large 11 um pixels in a 2k x 2k array. The sensor size is 22.5 mm x 22.5 mm yielding a good field of view even at longer focal lengths.
