QE graph & Read noise
QE and Read noise are the most important parts to measure the performance of a camera.
Higher QE and Lower read noise are needed to improve the SNR of an image.
The following figure shows the QE curve of ASI585. According to our measurement, the QE peak
of ASI585 is 91%.
As you can see from the camera performance graph, the readout noise of ASI585 is very low. The
built-in HCG mode can even more reduce readout noise at high gain and keep the same wide
dynamic range for this camera as at low gain. When you set gain at 252, the HCG mode will be
automatically turned on. Readout noise in this case can be as low as 1.5e while the dynamic range
can still be close to 11bit.
