1.CCD readout noise: the RMS value of the CCD readout noise at the minimum integration time.
2.CCD dynamic range: calculated under minimum integration time as (saturation value − dark noise baseline) / standard deviation of CCD readout noise, evaluated according to Oceanhood Opto-Electronics standards.
3.Response linearity: The response nonlinearity is measured before calibration. |
