| The electro-optical specifications of the Extended Dynamic Range CEMs are valid for all models. Different are the sizes of the entrance funnels, the shape of the funnels (round, rectangular or square), and the angles between funnels and the CEM bodies. The dark count rates depend on the CEM opening and are at a minimum for smaller openings. Figures 1 - 6 show typical data plots for the Extended Dynamic Range CEMs measured with our test equipment. |
