: Optimization of system performance for lowest noise or highest SNR.
The number of pixels to be combined.
The charge accumulated within a well, in the absence of light.
The length of time that a CCD/CMOS is accumulating charge.
Unwanted signal or disturbance that is generated by the on-chip amplifier
The ratio of the measured signal to the overall noise at that pixel.
Defined as the linear full well (e-) divided by read noise (e-).
Spherical photon flux:
The number of photons intercepted by a sphere per unit time.
Relationship between the detected electrons and A/D units generated
Statistical nature of the EMCCDs results in excess noise between 1 to 1,4.
: Electrons are accelerated from pixel to pixel in the multiplication register.
Correlated Multiple Sampling, a effective noise reduction technique.
Note: * The actual values may be 50-100 counts higher because of the Baseline Offset.
