Typical Operation360 V———0.0003 mA

Application Notes

The high voltages required for the Intensifier and the image section of the Esicon can be obtained from a small size modular power supply. Requirements for the scanning section are similar to those of a standard 1 inch magnetically focused and deflected Vidicon. Signal can be integrated for several minutes without degradation.
