Quantum Efficiency
The QE curve and readout noise are very important parameters to mesure the camera's performance. Higher OE and lower readout noise are necessary to improve the image signal-to-noise ratio.
HCG Mode
The camera has a built-in HCG mode, which can effectively reduce readout noise at high gain. This allows the camera to maintain the same high dynamic range as it does at low gain. When the gain is 182, the HCG mode is automatically turned on. The readout noise is as low as 0.8e, and the dynamic range can still reach a level close to 11stops.
Dark Current Noise
The ASI678MC outperforms its predecessor, the ASI178, in terms of dark current noise. The lower noise levels contribute to smoother, cleaner frames, especially in long exposure scenarios.
