QHY42 BSI CLASS 2 CMOS IMAGER



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. 

QH-QHY42-QE-chart

 

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.
