WebGenerally, a reduction of the gain of the intensification stage is employed to limit the noise although intensified CCD cameras are available with a cooled photocathode. Intensified CCD cameras have a very fast response limited by the time constant of the output phosphor and often the CCD camera read out is the slowest step in image acquisition. WebFor example, a near-infrared viewer with the common S1 photocathode material (Ag-O-Cs: based on silver oxide, doped with cesium, used since 1930) is said to be usable for about 0.4 μm to 1.2 μm or even 1.3 μm; it is reasonably sensitive to 1064-nm light from a YAG laser (although much less than at 0.8 μm), while far higher intensities are ...
