The QHY2020 is a cooled scientific CMOS camera equipped with the GSENSE2020 back-illuminated CMOS sensor. Let’s explore its features:

  1. Sensor and Resolution:

  2. Special EUV/Soft X-ray Version:

  3. Dual Gain Mode:

  4. Frame Rates and HDR Mode:

    • The standard version of the QHY2020 uses a USB 3.0 interface.
    • It can achieve a maximum frame rate of 33 frames per second for single-channel 12-bit images or 21.5 frames per second for dual-channel 12-bit images (HDR mode).
    • The camera also supports selected regions of interest (ROI) for even faster rates, such as 450 FPS at 128 lines or 1460 FPS at 32 lines.
    • Customizable line readout modes are also available1.
  5. Cooling System:

  6. Optic Window and Adapters:

In summary, the QHY2020 is a versatile scientific CMOS camera suitable for spectrum analysis, fluorescence imaging, and specialized EUV/X-ray applications. Its high QE, low read noise, and flexible frame rates make it a valuable tool for astrophotography and scientific research12. You can find more information about this camera on the QHYCCD website.
