OCAM2K is a high speed low noise camera able to run at 2067 fps with sub-electron readout noise.To achieve this performance, OCAM2K uses the E2V CCD 220 EMCCD, an 8 output split frame transfer CCD. The CCD220 high speed metal buttressed clock lines are driven by OCAM2K at a speed as high as 7 Mlines/s transferring each frame in the store section in only 12 microseconds, to minimize smearing.
