The standard version of the QHY2020 is USB3.0. It can produce a maximum frame rate of 33 frames per second for single channel 12bit images, or 21.5 frames per second for dual channel 12-bit images (HDR mode). The camera can also transfer selected regions of interest for extremely fast rates, e.g., 450 FPS at 128lines, 1460 FPS at 32 lines. This specially addressed line readout mode can also be customized.

Astronomical Imaging

With ultra high QE and ultra low read noise, the QHY2020 is an ideal camera for time-domain astronomy, autoguiding large professional telescopes, and transient source detection and spectrum analyze.

Biological Imaging

The 13.3mm x 13.3mm sensor size is well matched to a microscope image circle. Microscopy applications will benefit from its high QE, low noise and fast readout. The QHY2020 is an ideal scientific CMOS camera for Fluorescence imaging.

Spectroscopy

The high, wide response from NIR to UV makes the QHY2020 a perfect camera for spectrum analysis and spectrum imaging systems.
