5. 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.
Color 385 Sensor Relative QE
Read Noise includes pixel diode noise, circuit noise and ADC quantization error noise, and
the lower the better.
The Read Noise of the ASI385 cameras is extremely lower when compared with traditional
CCD cameras. It is even lower when the camera is set at a higher gain.
Depending on your target, you can set the Gain lower for higher Dynamic Range (longer
exposure) or set the Gain higher for lower noise (such as short exposure or lucky imaging).
