ASI290 Manual 5. QE Graph & Read Noise QE and Read Noise are the most important parameters to measure the performance of a camera. Higher QE and lower Read Noise are needed to improve the SNR of an image. Mono 290 sensor Relative QE Curve Color 290 sensor Relative QE Curve... - Page 8 ASI290 Manual Read Noise includes pixel diode noise, circuit noise and ADC quantization error noise, and the lower the better. The Read Noise of the ASI290 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).
