L3Vision CCD performance

Theoretical modelling of L3Vision CCDs from E2V Technologies indicate that these devices have the potential to act as an image plane photon-counting array. The distribution of output electrons can be modelled numerically for any given flux of detected photons.

Experimental measurements of L3Vision CCDs in our camera both at the NOT and in the laboratory indicate that short exposures are often affected by charge transfer efficiency problems at low signal levels.
